    [0001] An article of footwear with improved structure The invention relates to an article of footwear, such as a shoe or any equivalent. The footwear can be used in areas such as walking, running on flat terrain or in the mountains, wheeling, ball sports, cross-country skiing, snow surfing, snowshoeing, snowshoeing and snowboarding. bike or other. The article of footwear must fulfill various functions, sometimes antithetical, such as ensuring a maintenance and / or a sufficient tightening of the foot while offering a satisfactory comfort. The article of footwear must also have a certain flexibility, a quality which consists in a good aptitude for marrying certain deformations of the foot. In other words, the article of footwear must adapt to the foot by leaving it the latitude necessary for the walk or the sport in question. To do this it is known to manufacture footwear, such as shoes, by association of a rod and a sole. The upper generally comprises a number of parts, such as a side section, a medial area, a vamp, a tongue, a heel, a rear buttress, a front protection cap, a tightening device including passers-by and a lace, a lining. internal, or even other parts. In addition, some of these may include several parts. The main problem in a shoe is to assemble and put into a three-dimensional shape pieces cut and assembled flat. The rod is associated, in known manner, with a mounting flange, to delimit a footwear element. According to a first method, the rod is glued to the mounting flange by a layer of glue. The mounting flange, also called the first mounting, is relatively rigid, to resist the mounting process. The gluing is done by pulling the rod to press it on the first of assembly, knowing that a form is inserted in the stem. This is called traditional form fitting. This technique allows to exert sufficient pressure during the heating of the glue, to obtain the footwear element. A second method, also known, is to achieve the footwear element by joining the rod to the first mounting by means of a seam. This is called Strobel editing. The first assembly is here a flexible sole, which can be sewn, called Strobel sole. For each of the first and second methods, the first assembly is part of the assembly. The latter further comprises external parts, such as one or more damping layers, as well as a wear layer, provided for contacting the ground, which are generally fixed by gluing on the first mounting and on the rod mounted on form . The sole comprises one or more inner layers, disposed in the footwear element, to perform protective functions in terms of hygiene, damping, arch support, or other. In the end, the combination of the footwear element with the other components of the sole formation form the shoe. It is observed that, whatever the method used for its manufacture, a shoe according to the prior art has certain drawbacks. First, the shoe uses a high number of pieces, generally between forty and sixty. Because the number of pieces constituting the shoe is high, the number of manufacturing operations and the time required to conduct them are high. It usually takes forty minutes to an hour and thirty minutes to make a shoe. It can be said that shoes made by conventional techniques are complicated by both the number of their components and the number of manufacturing operations. Another disadvantage results from the structural discontinuity of the shoe, especially at the stem. For example, a small-sized piece superimposed on another larger one can sometimes greatly change the bending ability of the rod where the small piece is located. This can sometimes annoy a user and make it more difficult to shape, that is to say in three dimensions, the rod. Another disadvantage comes from the existence of free spaces between the foot and the shoe. This means that in some places the foot is not in contact with the rod, or with the sole. This is particularly true at certain portions of the junction between the rod 15 and the first assembly. As a result sometimes there is inadvertent movement between the foot and the shoe, which can be a source of embarrassment or trauma. It also sometimes appears spaces between the foot, the ankle or the lower leg and the stem, at the opening of donnage. As a result, foreign bodies may inadvertently enter the shoe.
    [0002] Finally, it can be said that a shoe according to the prior art does not always ensure a sufficient hold and / or tightening of the foot, or does not always offer him a satisfactory comfort. In addition this shoe does not systematically marry all the deformations of the foot. In relation to this, the Applicant has proposed another approach to manufacturing an article of footwear.
    [0003] For example, according to the document FR 2 999 881, a footwear article comprises one or two envelopes, each envelope extending in length from a rear end to a front end, in width between a lateral edge and a medial edge, and in height from a bottom to an upper end, each envelope comprising son mechanically connected to each other.
    [0004] The envelopes are shaped in volume, that is to say in three dimensions, being placed on a shape to present a geometry very similar to that of a foot, and thus they marry the foot very homogeneously . This means that the foot is in contact with, or at least very close to, the envelopes. This results in a uniform support of the foot with very little unwanted movement between the latter and the envelopes, or even with no displacement. An advantage that arises is an increased comfort of the article of footwear, compared to a shoe according to the traditional prior art. The arrangement according to FR 2 999 881 also shows that each envelope has continuity of structure, in the sense that its internal surface and / or its external surface are, if not totally regular, at least essentially regular. This results advantageously that the user is less embarrassed, if at all. The synthesis of the above shows that the envelopes maintain the foot and provide a satisfactory comfort. In addition each envelope is able to marry the 5 deformations of the foot. This makes the article of footwear according to document FR 2 999 881 comfortable in any situation, whether static or dynamic. We note additionally by the arrangement according to FR 2 999 881 a reduced number of parts to manufacture the footwear. In relation to this, the invention generally seeks to further improve a footwear article. More specifically, the invention wants, for example, to improve the transmission of driving pulses, the restitution of the reactions of the ground or of a machine, or the perception of sensory information. The invention seeks to optimize the efficiency of use, and reduce the fatigue of a user. The invention still seeks to meet the specific needs of a user, retaining its basic qualities such as comfort and foot support. In the case of search support or transmission of intense information, for example during sports use, it is a real challenge. Indeed, the comfort and the optimization in the transmission of the efforts are concepts a priori antinomic. To meet the problem described above, the invention proposes a footwear article which comprises a first envelope, the first envelope extending in length from a rear end to a front end, in width between a lateral edge and a medial edge, and in height from a bottom to an upper end, the first envelope comprising son mechanically linked to one another, the first envelope defining a reception volume of a foot, the footwear comprising a Second envelope, the second envelope extending in length from a rear end to a front end, in width between a lateral edge and a medial edge, and in height from a bottom to an upper end, the second envelope; comprising wires mechanically connected to each other, the second envelope defining a reception volume of one foot, the first envelope and the second the envelope being arranged opposite one another. The article of footwear according to the invention is characterized in that at least at least one subdivision comprises a reversibly resiliently deformable intermediate piece, the insert being disposed between the first envelope and the second envelope.
    [0005] This makes it possible to give the footwear one or more specific properties at a given location. For example at the upper ends of the envelopes, as will be explained in more detail later, the insert may be a tongue. Or at the fund level, as will be explained in more detail later, the insert may be a portion of sole. In each case, the intermediate piece 3024022 4 allows a relative movement of the portions of the envelopes opposite which it is. Because it is able to crush elastically in a reversible manner, the insert allows the relevant portions of the envelopes to approach one another, for example during special solicitations, to then find their distance from each other. natural gauge. This distance corresponds to the thickness of the insert. By crashing, the spacer spreads a portion of the compression forces in directions other than a direction perpendicular to it and thus dampens these forces. In other words, the intermediate part enlarges the transmission surface of the efforts related to the use of the article, the different pulses, or sensory information. This presents an advantage which is the improvement of the comfort of the article of footwear. Surprisingly, the transmission of forces, pulses or information is not impaired. The invention thus succeeds in ensuring that the article is both comfortable and precise in its uses. This improves the user's performance, and reduces his fatigue. In general, it can be said that the invention improves the structure and the method of manufacture of an article of footwear. Other features and advantages of the invention will be better understood with the aid of the following description, with reference to the appended figures, which illustrate, according to non-limiting embodiments, how the invention can be realized, and in which: FIG. 1 is a front perspective view of a footwear item, top side, according to a first embodiment of the invention, FIG. 2 is a section along II-II of FIG. 3 is a diagrammatic perspective view of a blank and a spacer before assembling with each other, the blank being used to manufacture a first casing and a second casing of the article of footwear in accordance with FIG. 1, FIG. 4 is similar to FIG. 3, in a case where the blank and the intermediate part are assembled together, FIG. 5 is a diagrammatic view relating to the constitution of an envelope of Article 30 FIG. 6 is another schematic view relating to the constitution of an envelope of the article of footwear according to FIG. 1, FIG. 7 is another schematic view relating to the constitution of an envelope of FIG. article of footwear according to FIG. 1, FIG. 8 is a side view of a reinforcement intended to be integrated with the article of footwear according to FIG. 1, FIG. 9 is a perspective view which relates to the manufacture of the footwear according to FIG. 1, FIG. 10 is another perspective view which relates to the manufacture of the footwear according to FIG. 1, FIG. 11 is a section similar to FIG. In another embodiment of the invention, Fig. 12 is a section similar to Fig. 2 for a third embodiment of the invention. The first embodiment that will be described after relates for example to an article of footwear for walking or for running on horizontal terrain or in the mountains. However, the first embodiment applies to other fields such as those mentioned before. The first form is described below with the help of Figures 1 to 10. As shown in Figures 1 and 2, a footwear 1 is provided to accommodate the foot of the user. It is agreed for the rest of the description to consider that the footwear article 1 is a shoe even though, as will be seen in detail below, its structure is completely unusual. Thus, the boot 1 extends in length, in a longitudinal direction L, between a rear end or heel 4 and a front end or tip 5, and in width, in a transverse direction W, between a lateral edge 6 and an edge medial 7. As shown in the shoe 1 comprises a lower portion 10, provided to surround the foot, excluding any high portion. However, it may alternatively be considered a shoe comprising both a low portion and a high portion, the latter being provided to surround the ankle and possibly the lower leg. According to the first embodiment described, the shoe 1 extends in height from a bottom 12 to an upper end 13, that is to say up to the free end of the lower portion 10 or the shoe 1. The bottom is a subdivision of the shoe on which the foot is supported. The shoe 1 is structured to allow a smooth running of the foot during walking, transmissions of sensory information, and impulses for support or receptions. This is why the shoe 1, or footwear, is relatively flexible. As will be detailed later, the shoe 1 comprises a first casing 21 which extends in length, in the longitudinal direction L, from a rear end 24 to a front end 25, in width, in the transverse direction W, between a lateral edge 26 and a medial edge 27, and in height from a bottom 28 to an upper end 29. This allows the first envelope to surround and maintain the foot of the user. For its constitution, the first envelope comprises threads connected to each other mechanically, as will be explained later. Also, for the first envelope, at least a portion of the son comprises at least one hot-melt filament, as will also be explained later. According to the first embodiment, and in a nonlimiting manner, the son of the first envelope which comprise at least one hot-melt filament are distributed over the entirety of the first envelope 21, and the fusion of the yarns contributes, to a greater extent 3024022 6 or less, depending on their quantity, their concentration, the strength and / or the bonding and / or the abrasion resistance of the first envelope. In fact, the fusion confers on the first envelope 21 the ability to retain its shape by itself. On the one hand, it can be said that the first envelope 21 is a one-piece piece and, on the other hand, that it can form a self-supporting part, giving its shape to the shoe, to a greater or lesser extent, depending the quantity / concentration of the threads. Consequently, the first envelope 21 gives or contributes to giving shape to the shoe 1. In other words, the rear end 24, the front end 25, the lateral edge 26, the medial edge 27, the bottom 28 and the upper end 29 of the first envelope delimit respectively the rear end 4, the front end 5, the lateral edge 6, the medial edge 7, the bottom 12 and the upper end 13 of the footwear or shoe 1. The minimalist structure adopted for the envelope 21 is a guarantee of simplicity, lightness, and many other advantages, as we will see later. Without limitation, still according to the first embodiment of the invention, the shoe 1 also comprises a second casing 31 which extends in length, in the longitudinal direction L, from a rear end 34 to an end before 35, in width, in the transverse direction W, between a lateral edge 36 and a medial edge 37, and in height from a bottom 38 to an upper end 39. The second envelope 31 covers the foot too, at Like the first 21. The second envelope 31 is disposed outside the first envelope 21 and thereby covers the foot indirectly. Finally, the shape of the shoe 1 is given both by the first envelope 21 and the second envelope 31. The first envelope 21 and the second envelope 31 are arranged opposite one another. Still in the spirit of the invention, the second envelope 31 comprises son connected to each other mechanically. Again, for the second envelope, at least a portion of the son comprises at least one hot melt filament, as will be explained later. The yarns which comprise at least one hot-melt filament are distributed over the entirety of the second envelope 31, and the fusion of the yarns contributes, to a greater or lesser extent, depending on their quantity and concentration, to the holding and / or the bonding and / or abrasion resistance of the second envelope. Here again the fusion confers on the second envelope 31 the ability to retain its shape by itself. On the one hand, it can be said that the second envelope 31 is a one-piece piece and, on the other hand, that it can form a self-supporting part, giving its shape to the shoe, to a greater or lesser extent, as a function of the quantity / concentration of the threads. As a result, the second casing 31 also gives or contributes to the shape of the boot 1. In other words, the rear end 34, the front end 35, the lateral edge 36, the medial edge 37, the bottom 38 and the upper end 39 of the second casing 31 also delimit respectively the rear end 4, the front end 5, the lateral edge 6, the medial edge 7, the bottom 12 and the upper end 13 of the article footwear or shoe 1. The minimalist structure 3024022 7 adopted for the envelope 31 is a guarantee of simplicity, lightness, and many other advantages, as we will see later. In order to better highlight the specific features of the invention, it is useful to specify how the envelopes 21, 31 are made. This is done in particular with reference to FIGS. 3 to 7. As can be seen throughout firstly for example in Figure 3, schematically, obtaining each envelope 21, 31 is made by manufacturing a sleeve 41, that is to say in fact a flexible tube made of son linked to each other mechanically. The sleeve 41 is a blank for the realization of the article 1. Non-limitingly, in correlation with the first embodiment, the sleeve 41 makes it possible to make both the first envelope 21 and the second envelope 31. sleeve 41 extends in length from a first end 42 to a second end 43. The first end 42 is closed by any technique known to those skilled in the art, such as a stitch after folding, the addition of a ferrule made of wires connected to each other mechanically, or any equivalent. The second end 43, for its part, is simply an opening. It can be seen that the sleeve 41 makes it possible to manufacture the envelopes 21, 31 in one piece. Here the first envelope 21 and the second envelope 31 extend one another. This simplifies manufacturing by reducing the number of parts and the time required for implementation.
    [0006] The combination of the threads used to make the sleeve 41, and thus the envelopes 21, 31, is presented with the aid of FIGS. 5 and 6. It is generally provided that the threads are mechanically linked to one another and are for example associated with each other by any suitable textile technique, such as knitting, weaving, braiding, or other. In the case of knitting, it is possible to use a circular loom with single needle or double needle, a cylinder loom, or a straight loom. Two knitting zones can be joined to each other by Intarsia technique or by embroidery. Various decorative patterns can be obtained directly during knitting, by the Intarsia method, embroidery, Jacquard technique, or other. Figure 5 symbolizes traditional weaving with first yarns 44 oriented in a first direction, second yarns 45 oriented in a second direction, the first 44 and second 45 yarns intersecting to form a flexible mesh. Figure 6, meanwhile, symbolizes a knitting here with three son 46, 47, 48 arranged in loops that interpenetrate. But, of course, many other arrangements are possible. The sleeve 41 is for example manufactured with a rectilinear loom, which makes it possible to vary the sections, that is to say in fact the diameter of the sleeve, to make variations of shape for the heel, to make openings for the passage of laces, to vary the density of the wall of the sleeve, or in particular to vary the tightening of the loops. In fact the rectilinear craft offers a wide range of adjustment possibilities, and it is suitable for making sleeves of all sizes, either in diameter or in length. As such, the straight line is more practical than the circular loom. Indeed, it works on a reduced range in the diameter of the sleeve. It is therefore necessary to use several different circular looms to make a complete range of sleeves 41, that is to say a complete range of shoes where all sizes are represented where a single straight loom is sufficient. Finally a rectilinear craft allows to make one or more envelopes in three dimensions, with all the desired characteristics, and the desired size. It is also useful to recall what is a wire within the meaning of the invention. First of all the yarn may be a monofilament, obtained for example by extrusion of a hot melt synthetic material, such as polyamide, polyurethane, polyethylene, or any equivalent material or the like. The production of a filament is continuous, comparable to the silk filament produced by a spider. It should be noted in passing that the filament may be single-component, or mono-material, in the sense that its cross-section is regular. But the filament can also be multi-component, for example two-component. In the latter case, a cross-section of a filament shows a core consisting of a first material, and a peripheral envelope which surrounds the core, a shell made of a second material. Each material can be hot melt, or only one can be. If both materials are, their melting temperatures are different. Then the wire can be multi-filament. It is in this case obtained by association of several filaments. Such an association is represented by the scheme of FIG. 7. Here all the filaments 49 are of the same nature, in the sense that each of them has the same melting point. But we can provide combinations of filaments of different kinds, some of which may be fusible and others not, or with different melting points. The filaments are associated with each other by any known technique. Again, the yarn can be made in the form of a net of fibers. Here a fiber is a filament of limited length. The fibers are associated by close contact to form the net, by any known technique and in particular by torsion. The maintenance of the fibers to each other is traditionally made by friction, especially with natural fibers such as cotton. However, for the invention, the maintenance of the fibers to each other is done either by friction, or by combination of friction and melt adhesion, or completely by adhesion, because the invention uses hot melt materials . Having presented generally the structure of the sleeve 41, it will be possible further to explain its use for the manufacture of the shoe 1. However, beforehand, to stay in the spirit of the first embodiment, it is useful to explain that the footwear 1, or shoe, includes a reinforcement 51. It will be seen better after this reinforcement is associated with the envelopes 21, 31 by interlocking at the time of manufacture of the shoe 1, to give that specific skills. As shown in Figures 1, 2 and 8, the reinforcement 51 is a piece which extends in length from a rear end 54 to a front end 55, in width between a lateral edge 56 and a medial edge 57, and in height from a bottom 58 to an upper end 59. The reinforcement 51 has a length and a width similar to the lengths and widths of the envelopes 21, 31. Specifically the reinforcement 51 extends, in connection with the first 21, in length from the rear end 24 to the front end 25, in width between the lateral edge 26 and the medial edge 27, and in height from the bottom 28 5 to the upper end 29. This allows, by definition, to strengthen the first envelope 21, and therefore the footwear 1, especially at the bottom 12 and the periphery of the bottom. Not necessarily, the reinforcement 51 carries a clamping device 61. This comprises for example loops 62, located at the upper end 59, and a lace 63 and a locking device 64, known from the skilled person. It is therefore possible to tighten or loosen the reinforcement 51 and, in doing so, to tighten or loosen the boot 1, as it will appear later. By passing 62 is meant any device used to pass, slide a lace. The locking device is optional and can be replaced by a simple lace knot. More specifically, with respect to the first embodiment, the reinforcement 51 comprises a bottom 58, at least one side branch 65 extending from the bottom towards a free end 66 in a direction away from the bottom, free end 66 having a loop 62, at least one medial branch 67 extending from the bottom towards a free end 68 in a direction away from the bottom, the free end 68 having a loop 62, and at least one lace 63 walking by passersby. In a nonlimiting manner, the reinforcement 51 comprises four lateral branches 65, as well as four medial branches 67. But these numbers can respectively be different. It also appears that each branch 65, 67 has a loop, which is made by any technique known to a person skilled in the art. Finally, the reinforcement associated with the clamping device allows a uniform clamping of the envelopes 21, 31, and therefore the foot consequently.
    [0007] In particular for the purpose of optimizing the comfort of the article of footwear 1, as is understood in particular by means of FIGS. 1 and 2, the lateral branch 65 and the medial branch 67 are arranged in part at least between the first 21 and the second casing 31, and the loops 62 are disposed outside the first casing 21 and also outside the second casing 31.
    [0008] According to the invention, as can be understood by means of the set of FIGS. 1 to 10, at the level of at least one subdivision, the article of footwear comprises an intermediate piece 71 which is elastically deformable in a reversible manner, the piece interlayer 71 being disposed between the first envelope 21 and the second envelope 31. This is, as we have seen in a general manner, allow a relative approximation of two subdivisions of the envelopes 21, 31 35 which are opposite the one of the other, even if the intermediate piece separates them locally. The insert is compressed proportionally to efforts related to the use of the article, to resume its initial thickness when the efforts disappear. In doing so, the spacer absorbs some of the compressional energy applied thereto, and also diffuses a portion of this energy in directions other than a perpendicular direction. This reduces the specific pressure at the level of the envelopes, for a better comfort. With respect to the first embodiment of the invention, the insert 71 has an elongate shape and is intended to extend under the clamping / lacing system so as to protect the instep of the instep. user and so she defines a tab. The tongue 71 is located at the upper ends 29, 39 of the first 21 and second 31 envelopes, the tongue 71 extending in length from a rear end 74 to a front end 75, in width between a lateral edge 76 and a medial edge 77, and in thickness between a bottom 78 and a top 79. This is to improve the comfort of the article 10 footwear at the upper ends of the envelopes. For the user, it is the top of the foot that is better protected, ie the instep and / or the bending crease. In the example, the rear end 74 of the tongue is wider, which gives more or less the shape of a T. The tongue could also have a homogeneous rectangular shape, the essential being that it extends under the lacing and reconcile the functional aspects and lightness, as well as aesthetic depending on the case. The tongue could also have other functions than those described and for example aesthetic only. It can also be provided that the tongue extends only under the lacing portion (off), which always protects the instep. As is understood in particular by means of FIGS. 3 and 4, the rear end 74 of the tongue 71 is, in the example, secured to the first envelope 21 and / or the second envelope 31, a substantial part of the the remainder of the tongue being detached from the first casing 21 and / or the second casing 31. This has the consequence that the rear end 74 of the tongue is immobilized with respect to at least one casing, and that the rest, namely the central portion and the front end 75 can slide relative to the envelopes. This facilitates longitudinal flexing of the article of footwear, for a better running of the foot. In addition it is specified that the securing of the rear end is made by any appropriate means such as a bonding, or any equivalent or complementary technique. The fastening can be carried out in any other way. In an exemplary embodiment, the rear end 74 of the tongue is secured to the two envelopes 21, 31, which also allows to have an excellent finish at the aesthetic level. Referring to Figures 1 and 2, it can be seen that at least one passer 62 takes place above tab 71. In fact, according to the first embodiment but in a non-limiting manner, all the passers-by take place above of the tongue. This is to optimize comfort. Indeed, during a clamping action by the device 61 provided for this, it is the totality of the loops 62 which will press on the foot via the tongue. Of course the clamping system can also be realized differently, for example using eyelets.
    [0009] In order to fulfill its role under the best conditions, the tongue 71 comprises a layer of elastically deformable synthetic material. This layer may be an ethylene vinyl acetate (EVA) foam, a polyurethane foam, a polyethylene foam, or any other material capable of performing the same function. The tongue may comprise several parts, for example several layers, arranged relative to one another in an appropriate manner, and also include natural materials such as cork or any equivalent. Still in a nonlimiting manner according to one embodiment, at least one of the first 21 and second 31 envelopes has folds 81, 82, 83, 84 at the lateral edge 76 and / or at the medial edge 77 of the tongue 71. More precisely here, the first envelope 21 has a lateral fold 81 and a medial fold 82, and the second envelope 31 also has a lateral fold 83 and a medial fold 84. These folds allow variations in the volume of donning the article, because they make the geometries envelopes 21, 31 variables. In other words, the folds facilitate donning and heaving, 15 but disappear once the foot in the shoe. We can now address the use of the sleeve 41 for the manufacture of the shoe 1, according to Figures 9 and 10. In fact the constituents of the shoe 1 are assembled by hand, without complex and expensive machine as it was the case for the prior art. With Figures 9 and 10 it is understood that the sleeve 41 is threaded onto a part 86, called 20 form, which is in the image of the foot of the user. The sleeve is applied to the shape 86 in the manner of a sock on a foot. The sleeve 41 is shaped by the shape 86 thanks to its elasticity, which is due to its textile constitution. Then the reinforcement 51 is fitted on the subdivision of the sleeve 41 which will become the first envelope 21. Then the subdivision of the sleeve 41 which will become the second envelope 31 is folded over the reinforcement 51, thus covering the latter as well that the subdivision attributed to the first envelope. This is sufficient to constitute the subset of the shoe 1 which surrounds the foot subassembly which ultimately comprises the first envelope 21, the reinforcement 51, the second envelope 22 and the tongue 71. Note in passing that the second envelope 31 has orifices 87 for the passage of the free ends 66, 68 of the lateral branches 65 and medial 67 of the reinforcement 51. It is then sufficient to subject the subassembly to a temperature rise, by any appropriate technique, to melt just at the necessary level the hot-melt filaments of the envelopes, and thus give the shoe 1 its geometry. After heating, the form 86 can be removed from the subset. The shoe 1 is almost finished. It suffices, according to the first embodiment, to add an external sole 88. As can be seen in Figures 1 and 2 the footwear 1, or shoe, includes an outer sole 88. The latter is intended to take supported on the ground and, as such, is structured to resist frictional wear and also to cushion shocks. It therefore comprises, by way of example, a wear layer 89 and a damping layer 90. In FIG. 3024022 12 2, which is a cross section in the region of the boot intended to accommodate the foot arch of the foot. , it is found that the bottom 12 has a non-planar geometry, substantially identical to that of the vault mentioned above. The shoe 1 according to the invention is indeed able, as we said, to comply with the foot. It is therefore not essential, although it may be useful, to add to the shoe 1 an insole to replicate the arch, or other aspects of the underside of the foot. This thus simplifies the shoe 1 according to the invention with respect to a shoe according to the prior art. This also lighten the shoe 1 and, therefore, reduces mechanical inertia. An advantage that arises is the improvement of sports performance. The shoe according to the invention is suitable for example very well for a runner. FIG. 2 also shows that the reinforcement 51 is located almost entirely between the first envelope 21 and the second envelope 31. Still referring to FIG. 2, but also to FIG. 1, it is observed that the first envelope 21 and the second envelope 31 are continuous along a cross section. These envelopes therefore extend continuously at their respective upper ends 29, 39, even if they have folds, and thus at the upper end 13 of the shoe. The wrapping of the foot is therefore total and permanent. As can be understood from FIG. 1, but also from FIGS. 3 and 4, the boundary between the first envelope 21 and the second envelope 31 is a fold 93 which delimits a wearing opening 94. The periphery of the boot opening 94 is therefore delimited simply by folding the two envelopes 21, 31 one over the other. This means that this periphery has no seam or insert, as in the prior art, and that therefore the boot 1 is not a source of discomfort for the user including at the opening level. 94. The other embodiments of the invention are summarized below with reference to FIGS. 11 and 12. For the sake of convenience, it is above all the differences with respect to the first embodiment which are set out in FIG. evidence. In addition, it is intended to use the same references for like or similar elements as seen in the first embodiment. Thus, for the second embodiment, according to FIG. 11, there is an article of footwear or shoe 1, with its lateral 6 and medial edges 7, or its bottom 12 and its upper end 13. There is also the first envelope 21, the second envelope 31, the reinforcement 51, the loops 62, or the tongue 71.
    [0010] What is specific to the second embodiment is that it comprises another insert 101 placed between the two envelopes 21, 31. This insert 101 is a portion of a sole 102, the sole portion being located at the bottoms 28, 38 of the first 21 and second 31 envelopes, the sole portion 102 extending lengthwise from a rear end 104 to a front end 105, in width between a side edge 106 and a medial edge 107, and in thickness between a bottom 108 and a top 109. The portion 101 allows a relative movement of the portions of the envelopes opposite which it is. In this case, it is the whole or subdivisions of the funds 28, 38 of the envelopes 21, 31. Because it is capable of reversibly resiliently crushing, the intermediate part allows the portions concerned to envelopes to approach one another, for example during special requests, to then find their distance of natural spacing. This distance corresponds to the thickness of the insert. This is to get better damping shocks or pulses in the sole of the foot. An advantage which results for example is a better preservation of the user's joints. In a nonlimiting manner, according to the second embodiment of the invention, the intermediate part, namely the portion 101 of the sole assembly 102, extends opposite all the funds 28, 38 of the first 21 and second 31 envelopes. This makes it possible to obtain a damping effect at the level of the entirety of the bottom 12 of the article of footwear.
    [0011] The intermediate piece 101, added as described in connection with the tongue 71, is for example secured to the first casing 21 and / or the second casing 31. The joining is done by any appropriate means such as a bonding, or any equivalent or complementary technique. This optimizes the cooperation between them of the bottoms 28, 38 of the envelopes 21, 31, in the sense of a more precise transmission of the pulses or the sensory information. But it can alternatively be planned to have the insert without interlocking with the funds. In order to perform its role under the best conditions, the insert 101 comprises a layer of elastically deformable synthetic material. This layer may be an ethylene vinyl acetate (EVA) foam, a polyurethane foam, a polyethylene foam, or any other material capable of performing the same function. The intermediate part or portion 101 may comprise several parts, for example several layers, arranged relative to each other appropriately, and also include natural materials such as cork or any equivalent. In addition, it can be observed that the article of footwear 1 comprises a wear layer 111 and at least one intermediate layer 112 situated between the wear layer 111 and the bottoms 28, 38 of the envelopes 21, 31, the diaper 111 wear and the intermediate layer 112 constituting an outer sole. This allows a certain level of damping directly at the level of the wear layer. Now for the third embodiment of the invention, according to Figure 12, there is still an article footwear or shoe 1, with its side edges 6 and medial 7, or its bottom 12 and its upper end 13. Found also the first envelope 21, the second envelope 31, the reinforcement 51, the loops 62, or the tongue 71. Like what has been seen for the second, the article in the third form comprises another intermediate piece 121 between the two envelopes 21, 31. This insert 121 is a portion of a sole assembly 122, the sole portion being located at the funds 28, 38 of the first 21 and second 31 envelopes, the portion 121 of soleing 122 extending in length from a rear end 124 to a front end 125, in width between a lateral edge 126 and a medial edge 127, and in thickness between a bottom 128 and a top 129. The portion 121 allows a dépl the relative portions of the envelopes against which it is located. In this case, it is the totality or subdivisions of funds 28, 38 envelopes 21,31. Because it is able to crush elastically in a reversible manner, the insert allows the relevant portions of the envelopes to approach one another, for example during special solicitations, to then find their distance from each other. natural spacing. This distance corresponds to the thickness of the insert. This is to get better damping shocks or pulses in the sole of the foot. An advantage that results for example is a better preservation of the user's joints. In a nonlimiting manner, this third embodiment of the invention, the insert, namely the portion 121 of the sole assembly 122, extends opposite all the funds 28, 38 of the first 21 and second 31 envelopes. This makes it possible to obtain a damping effect at the level of the entirety of the bottom 12 of the article of footwear. The intermediate piece 121 is for example secured to the first casing 21 and / or the second casing 31. The joining is done by any appropriate means such as a bonding, or any equivalent or complementary technique. This optimizes the cooperation between them of the funds 28, 38 of the envelopes 21, 31, in the sense of a more precise transmission of the pulses or the sensory information. But it can alternatively be planned to have the insert without interlocking with the funds. In order to fulfill its role under the best conditions, the spacer part 121 comprises a layer of elastically deformable synthetic material. This layer may be an ethylene vinyl acetate (EVA) foam, a polyurethane foam, a polyethylene foam, or any other material capable of performing the same function. The intermediate piece or portion 121 may comprise several parts, for example several layers, arranged relative to one another in an appropriate manner, and also include natural materials such as cork or any equivalent. What is specific to the third embodiment of the invention is that the article of footwear 1 comprises a wear layer 131 secured directly to a bottom 38 of an envelope. In this case, it is the bottom 38 of the second envelope 31, which defines the outside of the footwear. This architecture promotes more direct transmission of driving impulses and sensory information. In other words, the cushioning portion 121 of the sole assembly is fully integrated into the upper, which gives the shoe a particular aesthetic appearance, only the outsole being visible. Thus, with the aid of a very simple construction and a very interesting manufacturing cost, the aesthetic effect of a construction of the double-lasting type 3024022 is much more expensive to implement. It is also possible to have a combination of the two embodiments of FIGS. 11 and 12, namely an insert 101 placed between the two envelopes 21, 31 or an envelope and the reinforcement 51, for the internal sole assembly, and a spacer part 121. disposed between the two envelopes 21, 31 as shown in Figure 12 for the outer sole. In both cases, the fact of enclosing the damping intermediate piece 101, 121 of the sole assembly makes it possible to use a much larger choice of material, since stresses such as abrasion resistance stress can then be ensured by the envelope or envelopes 21, 31. Furthermore, since they are not visible and therefore not subject to the aesthetic imperatives, these intermediate pieces can be made by cutting, rather than molding, which further reduces the manufacturing costs and opens up even further. more choice in terms of usable materials for these intercalated parts. The invention is not limited to the embodiments described above, and includes all technical equivalents that fall within the scope of the following claims. In particular, it may be provided to add one or more intermediate pieces in another part of the article of footwear and, for example forward to form a toe protection toe, backwards to provide support additional heel, or at an edge to protect the ankle.
    [0012] It may also be provided to add one or more envelopes to the article of footwear 1.
