    1 160313SE I NSOLE FOR FOOTW EAR Technical Field The present disclosure generally relates to insoles for footwear. lnparticular, an insole comprising at least one reinforcing bridge and a footwear comprising the insole are provided.
    Background Various solutions exist for insoles in order to improve the anatomicalposition of the foot in the shoe and prevent injuries and/or pain. Someinsoles provide support to the three arches of the foot: the anterior arch,the medial arch and the lateral arch, for example by means of inserts in the insole or by means of locally thicker regions in the insole.
    US 20130111781 A1 discloses an orthopaedic shoe insert to support andguide the foot. The shoe insert comprises an insert core having a carrierand a support clasp. The support clasp com prises two individually adjustable diagonally opposite support arms having a higher mechanical strength.
    Summary Some prior art insoles comprise arch supports with an initial shape whenthe insole or shoe is new. However, many of these prior art arch supportschange in shape over time when the shoe is used, for example due tocompression forces from the wearer's weight, impacts, moisture, materialageing and/or exposure to sunlight. As a consequence, the arch supportsmight lose their intended function and the wearer might get injuries inthe feet, knees, hip and/or back. The shoe might also become painful to Wear.
    Many of these types of prior art insoles do also not provide a sufficient 2 160313SE rigidity in terms of twisting forces along the longitudinal axis of theinsole. This type of twisting of the feet might also lead to injuries and pain.
    On the other hand, some prior art insoles comprise more rigid archsupports that better maintain their initial shape over time. However,these prior art insoles are often too rigid and thereby impair the flexibilityof the feet and prevent the natural movements of the feet when walkingor running. Although some problems related to a lack of arch supportmay be avoided with these types of insoles, the inflexible design mightcause new types of injuries and pain. These types of prior art insoles alsooften use an excess amount of material for the supports leading to a higher weight of the shoe and added costs.
    One object of the present disclosure is to provide an insole that gives ananatomically correct support to the anterior arch of the foot and maintains this support over time.
    A further object of the present disclosure is to provide an insole thatgives an anatomically correct support to the medial arch and the lateral arch of the foot and maintains this support over time.
    A still further object of the present disclosure is to provide an insole that reduces twisting of the insole about a longitudinal axis of the insole.
    A still further object of the present disclosure is to provide an insole thathas good flexibility to allow the foot to move during walking and/or running.
    A still further object of the present disclosure is to provide an insole that has a simple structure and enables a simple and cheap production.
    A still further object of the present disclosure is to provide an insole that has a low weight.
    According to one aspect of the present disclosure, there is provided an insole for footwear, the insole comprising an anterior arch support; and 3 160313SE an anterior reinforcing bridge having a raised section for providingresistance against compression of the anterior arch support. The raisedsection is raised vertically with respect to a general horizontal plane of the insole.
    The anterior reinforcing bridge thus adds rigidity to the anterior archsupport and contributes to maintaining the original shape of the anteriorarch support over time. Throughout the present disclosure, the anteriorreinforcing bridge may alternatively be referred to as an anterior stiffener, an anterior stabilizer, an anterior beam or an anterior bar.
    The anterior arch support of the insole may comprise or be constituted bya shock absorbing material or damping material (e.g. PORON ®). Thedamping material may be locally provided to the anterior arch support.Alternatively, the insole may comprise a damping layer. This dampinglayer may have a substantially uniform thickness but once laid upon theanterior reinforcing bridge it may define the anterior arch support of the insole.
    The anterior arch support may have a generally circular or droplet shapedappearance. lf a droplet shape is employed, the droplet may pointbackwards in a longitudinal direction of the insole, i.e. towards a heelregion of the insole. The anterior arch support may be successively vertically raised with respect to the adjacent surface of the insole.
    The anterior arch support may have a maximum length in thelongitudinal direction of the insole that is 10% to 30%, such as 15% to25%, such as 18% to 22%, such as 20%, of the length of the insole inthe longitudinal direction. Moreover, the anterior arch support may havea maximum length in the lateral direction (width direction) of the insolethat is 40% to 60%, such as 45% to 55%, such as 48% to 52%, such as50%, of the local width of the insole in the lateral direction where the anterior arch support is provided. 4 160313SE The anterior arch support may be positioned (e.g. with its geometricalcenter point) at a distance from a front tip of the insole that is 35% to45%, such as 38% to 42%, such as 40%, of the longitudinal length ofthe insole. The anterior arch support may be substantially centered in the lateral direction of the insole.
    The anterior reinforcing bridge may extend substantially in a lateraldirection of the insole. Thus, the anterior reinforcing bridge may have anelongated appearance. As seen from above, the anterior reinforcing bridge may be substantially straight.
    The anterior reinforcing bridge may be positioned (e.g. with itsgeometrical center point) at a distance from a front tip of the insole thatis 30% to 50%, such as 35% to 45%, such as 37% to 41%, such as39%, of the longitudinal length of the insole.
    The anterior reinforcing bridge may have a width in the longitudinaldirection of the insole that is 2% to 6%, such as 4%, of the longitudinallength of the insole. Alternatively, the anterior reinforcing bridge mayhave a width in the longitudinal direction of the insole of 5 to 15 mm,such as 8 to 12 mm, such as 9 to 11 mm, such as 10 mm. ln otherwords, the length of the anterior reinforcing bridge may be independent of the size of the footwear.
    The raised section of the anterior reinforcing bridge may span oversubstantially the entire width of the insole. ln other words, the anteriorreinforcing bridge may have a generally arc shaped appearance.Alternatively, the raised section of the anterior reinforcing bridge mayonly span over a partial distance (e.g. a central section) of the width ofthe insole. For example, the raised section may be an intermediate raisedsection of the anterior reinforcing bridge arranged between two furthersections (e.g. two substantially flat sections). ln these alternativevariants, the intermediate raised section may have a length in the lateraldirection that is 30% to 70%, such as 40 to 60%, such as 50%, of the 5 160313SE local lateral width of the insole where the anterior reinforcing bridge is provided.
    As used herein, a substantially perpendicular/parallel relationshipincludes a perfectly perpendicular/parallel relationship as well asdeviations from a perfectly perpendicular/parallel relationship with up to10%, such as up to 5%, such as up to 2%. Similarly, a substantiallycorresponding distance as used herein includes a perfectly correspondingdistance as well as deviations from a perfectly corresponding distance with up to 10%, such as up to 5%, such as up to 2%.
    The anterior reinforcing bridge may be convex as seen in an anteriordirection of the insole. The anterior reinforcing bridge may thus have asubstantially downwardly directed cavity and/or a substantially upwardlydirected bulge. An anterior direction of the insole and a forwardlongitudinal direction of the insole as used herein are intended to be thesame direction. These directions are directions along the anterior axis or the longitudinal axis of the insole.
    The insole may further comprise a medial arch support; a lateral archsupport; and at least one transverse reinforcing bridge having two raisedsections for providing resistance against compression of the medial archsupport and the lateral arch support, respectively. Each of the medialarch support and the lateral arch support may have a generally archshaped appearance as seen from above. The arc may point inwardssubstantially in the lateral direction of the insole. The medial arch supportand the lateral arch support may be successively vertically raised with respect to the adjacent surface of the insole.
    The at least one transverse reinforcing bridge thus adds rigidity to themedial arch support and the lateral arch support and contributes tomaintaining the original shape of the medial arch support and the lateralarch support over time. l/loreover, the at least one transverse reinforcingbridge prevents the insole from bending about a central longitudinal axis.
    Throughout the present disclosure, the transverse reinforcing bridge may 6 160313SE alternatively be referred to as a transverse stiffener, a transverse stabilizer, a transverse beam or a transverse bar.
    The medial arch support may have a length in the longitudinal directionof the insole that is 35% to 60%, such as 40% to 55%, such as 45% to50%, such as 48%, of the length of the insole in the longitudinaldirection. The lateral arch support may have a length in the longitudinaldirection of the insole that is 40% to 65%, such as 45% to 60%, such as50% to 55%, such as 53%, of the length of the insole in the longitudinal direction.
    The medial arch support may be positioned (e.g. with its geometricalcenter point) at a distance from a front tip of the insole that is 55% to70%, such as 60% to 65%, such as 63%, of the longitudinal length ofthe insole. Also the lateral arch support may be positioned (e.g. with itsgeometrical center point) at a distance from a front tip of the insole thatis 55% to 70%, such as 60% to 65%, such as 63%, of the longitudinal length of the insole.
    The medial arch support and the lateral arch support of the insole maycomprise or be constituted by a shock absorbing material or a dampingmaterial (e.g. PORON ®). The damping material may be locally providedto the medial arch support and the lateral arch support, respectively.Alternatively, the insole may comprise a damping layer. This dampinglayer may have a substantially uniform thickness but once laid upon theone or more transverse reinforcing bridges, it may define the medial arch support and the lateral arch support of the insole.
    One or each of the transverse reinforcing bridges may extendsubstantially in a lateral direction of the insole. Thus, each transverse reinforcing bridge may have an elongated appearance.
    The at least one transverse reinforcing bridge may extend substantially ina lateral direction of the insole. The insole may comprise two substantially parallel transverse reinforcing bridges. 7 160313SE ln case the insole comprises two transverse reinforcing bridges, a firstanterior transverse reinforcing bridge may be positioned (e.g. with itsgeometrical center point) at a distance from a front tip of the insole thatis 50% to 65%, such as 55% to 60%, such as 57%, of the longitudinallength of the insole. A second posterior transverse reinforcing bridge maybe positioned (e.g. with its geometrical center point) at a distance from afront tip of the insole that is 65% to 75%, such as 68% to 72%, such as70%, of the longitudinal length of the insole.
    Each of these two transverse reinforcing bridges may have a width in thelongitudinal direction of the insole that is 2% to 6%, such as 4%, of thelongitudinal length of the insole. Alternatively, the transverse reinforcingbridge may have a width in the longitudinal direction of the insole of 5 to15 mm, such as 8 to 12 mm, such as 9 to 11 mm, such as 10 mm. lnother words, the width of the transverse reinforcing bridge may be independent of the size of the footwear.
    As a further example, the insole may comprise only one single transversereinforcing bridge. This single transverse reinforcing bridge may beconstituted by one of the two transverse reinforcing bridges as describedabove and positioned at one of the described positions. However, as oneexample, such single transverse reinforcing bridge may be positioned(e.g. with its geometrical center point) at a distance from a front tip ofthe insole that is 55% to 75%, such as 60% to 70%, such as 62% to 66%, such as 64%, of the longitudinal length of the insole.
    Alternatively, the insole may comprise only one relatively wider singletransverse reinforcing bridge. This single transverse reinforcing bridgemay be positioned (e.g. with its geometrical center point) at a distancefrom a front tip of the insole that is 55% to 75%, such as 60% to 70%,such as 62% to 66%, such as 64%, of the longitudinal length of theinsole. However, the width of such relatively wider single transversereinforcing bridge in the longitudinal direction of the insole may be 10%to 30%, such as 15% to 25%, such as 17% to 21%, such as 19% of the longitudinal length of the insole. Alternatively, the single wider transverse 8 160313SE reinforcing bridge may have a width in the longitudinal direction of theinsole of 30 to 60 mm, such as 40 to 50 mm, such as 45 mm. ln otherwords, the length of the transverse reinforcing bridge may be independent of the size of the footwear.
    The at least one transverse reinforcing bridge may be concave as seen inan anterior direction of the insole. The at least one transverse reinforcingbridge may thus have a substantially upwardly directed cavity and/or a substantially downwardly directed bulge.
    The at least one transverse reinforcing bridge may have a continuousconcave arc shape. ln this case, the two ends of the arc shape mayconstitute the respective raised sections of the transverse reinforcing bridge.
    Alternatively, the at least one transverse reinforcing bridge may comprisea substantially straight intermediate section between two outer curvedsections constituting the respective raised section of the transversereinforcing bridge. ln other words, the at least one transverse reinforcingbridge may have a general shape of a widened ln this case, thelength of the intermediate section of the transverse reinforcing bridgemay be 40% to 55%, such as 45% to 50%, such as 48%, of the locallateral width of the insole where the transverse reinforcing bridge isprovided. Such intermediate section of the transverse reinforcing bridge may span between the lateral arch support and the medial arch support.
    The insole may further comprise at least one oblique reinforcing bridge inclined with respect to an anterior direction of the insole.
    Each of the oblique reinforcing bridges may extend at an angle withrespect to the anterior direction or the longitudinal direction of the insolefrom a posterior, medial point to an anterior lateral point of the insole. Amirrored configuration of the at least one oblique reinforcing bridge is also possible. Furthermore, each oblique reinforcing bridge may extend at 9 160313SE an angle with respect to the longitudinal direction of the insole that is 30°to 45°, such as 35° to 40°, such as 37°.
    The at least one oblique reinforcing bridge thus adds rigidity to themedial arch support and the |atera| arch support and contributes tomaintaining the original shape of the medial arch support and the |atera|arch support over time. Moreover, the at least one oblique reinforcingbridge prevents the insole from twisting about its longitudinal axis.Throughout the present disclosure, the oblique reinforcing bridge mayalternatively be referred to as an oblique stiffener, an oblique stabilizer, an oblique beam or an oblique bar.
    As one example, the insole may comprise two oblique reinforcing bridges.A first oblique reinforcing bridge may extend from a posterior point of themedial arch support to an anterior point of the |atera| arch support. Asecond oblique reinforcing bridge may be arranged posterior of the firstoblique reinforcing bridge and may also extend from a posterior point ofthe medial arch support to an anterior point of the |atera| arch support.The first and second oblique reinforcing bridges may be substantially parallel.
    Each oblique reinforcing bridge may have an elongated appearance. Asseen from above, each oblique reinforcing bridge may be substantiallystraight. Moreover, each oblique reinforcing bridge may have a width in adirection substantially perpendicular to its general extension direction of 5to 15 mm, such as8to 12 mm, such as9to 11 mm, such as 10 mm.
    As a further example, the insole may comprise only one single obliquereinforcing bridge. This single oblique reinforcing bridge may beconstituted by one of the two oblique reinforcing bridge as describedabove. However, such single oblique reinforcing bridge may optionally bewidened. For example, such widened oblique reinforcing bridge may havea width in a direction substantially perpendicular to its general extension direction of 30 to 50 mm, such as 35 to 45 mm, such as 40 mm. 10 160313SE The at least one oblique reinforcing bridge may comprise one or tworaised sections for providing resistance against compression of one or both of the medial arch support and/or the lateral arch support.
    The at least one oblique reinforcing bridge may have a continuousconcave arc shape. ln this case, the two ends of the arc shape may constitute the respective raised sections of the oblique reinforcing bridge.
    Alternatively, the at least one oblique reinforcing bridge may comprise asubstantially straight intermediate section between two outer curvedsections constituting the respective raised section of the obliquereinforcing bridge. ln other words, the at least one oblique reinforcingbridge may have a general shape of a widened the intermediatesection of the transverse reinforcing bridge may span between the lateral arch support and the medial arch support.
    As a further alternative, a first anterior oblique reinforcing bridge maycomprise only one raised section connected to a substantially straightsection. The single raised section of the first anterior oblique reinforcingbridge may be arranged to support the medial arch support. A secondposterior oblique reinforcing bridge may com prise a substantially straightintermediate section between two outer curved sections constituting theraised sections to support both the medial arch support and the lateralarch support. Alternatively, the second posterior oblique reinforcingbridge may comprise only one raised section connected to a substantiallystraight section. ln this case, the single raised section of the secondposterior oblique reinforcing bridge may be arranged to support the lateral arch support.
    Each reinforcing bridge as referred to herein may be a sheet of metal or hard plastics.
    The insole may further comprise a top layer, a bottom layer and a bridge layer wherein the bridge layer comprises the one or more 11 160313SE reinforcing bridges. The bridge layer may be an intermediate layer, i.e. provided between the top layer and the bottom layer.
    The insole may further comprise a damping layer. The damping layermay be an intermediate layer, i.e. provided between the top layer andthe bottom layer. The insole may comprise, in order from the top of theinsole: the top layer, the damping layer, the bridge layer and the bottom layer. Additional layers may or may not be provided.
    The bridge layer may only comprise the one or more reinforcing bridges.Thus, the one or more reinforcing bridges may be the only constituent(s)of the bridge layer. ln this manner, the flexibility of the insole can beimproved while stile providing an anatomical support. Moreover, the useof excess material can be avoided and the weight of the insole can be reduced.
    According to a further aspect, there is provided a footwear comprising aninsole according to the present disclosure. The footwear may for example be shoes, boots, sandals or slippers.
    The insole may be a partial insole. Such partial insole may be constitutedby an insert. ln case the insole is constituted by a partial insole, theexamples of positions, dimensions and orientations as given above applywith respect to a length and width of the inside of the footwear in whichthe insole is provided or is to be provided. The insole may be integrally formed with the footwear.Brief Description of the Drawings Further details, advantages and aspects of the present disclosure willbecome apparent from the following embodiments taken in conjunction with the drawings, wherein: Fig. 1:Fig. 2: schematically represents a bottom view of a foot;schematically represents a lateral side view of bones in the foot; 12 160313SE Fig. 3: schematically represents a top view of an insole; Fig. 4: schematically represents a bottom view of the insole; Fig. 5: schematically represents a top view of the insole andreinforcing bridges; Fig. 6a: schematically represents an anterior view of an anteriorreinforcing bridge; Fig. 6b: schematically represents an anterior view of an alternativeanterior reinforcing bridge; Fig. 7a: schematically represents an anterior view of a transversereinforcing bridge; Fig. 7b: schematically represents an anterior view of an alternativetransverse reinforcing bridge; Fig. 8a: schematically represents an anterior view of an obliquereinforcing bridge; and Fig. 8b: schematically represents an anterior view of an alternative oblique reinforcing bridge.
    Detailed Description ln the following, an insole comprising at least one reinforcing bridge anda footwear comprising the insole will be described. The same reference numerals will be used to denote the same or similar structural features.
    Fig. 1 schematically represents a bottom view of a foot 10. A typical foot10 (here a right foot) comprises an anterior transverse arch or anteriorarch illustrated by the lines 12, 14, a lateral longitudinal arch or a lateralarch illustrated by the lines 14, 16, and a medial longitudinal arch or medial arch illustrated by the lines 12, 16.
    Fig. 2 schematically represents a lateral side view of bones in the foot 10.
    The foot 10 comprises five metatarsals or metatarsal bones 18 locatedbetween the tarsal bones 20 and the phalanges. The phalanges are thebones in the toes and each toe except the large toe comprises a proximalphalange 22, an intermediate phalange and a distal phalange 24. The large toe only has two phalanges 22, 24. A metatarsal phalangeal joint 13 160313SE 26 joins each metatarsal 18 to a respective proximal phalange 22. Themetatarsal heads 28 are the ends of the metatarsals 18 closest to the proximal phalanges 22.
    As can be seen in Fig. 2, the anterior arch 12, 14 is located below themetatarsal heads 28. The medial arch 12, 16 spans from below the firstmetatarsal head 28 to below the calcaneus 30. The Iateral arch spansfrom below the fifth metatarsal head 28 to below the calcaneus 30. Fig. 2 further illustrates a vertical direction 32 with respect to the foot 10.
    Fig. 3 schematically represents a top view of an insole 34. The insole 34comprises a toe region 36 and a heel region 38. The insole 34 may be inserted in various types of footwear.
    Also illustrated in Fig. 3 is a coordinate system showing an anteriordirection 40, a posterior direction 42, a medial direction 44 and a Iateraldirection 46. The anterior direction 40 may alternatively be referred to asa forward longitudinal direction and the posterior direction 42 mayalternatively be referred to as a rearward longitudinal direction.Moreover, since the insole 34 in Fig. 3 is for a right foot 10, the Iateraldirection 46 may alternatively be referred to as a Iateral right directionand the medial direction 44 may alternatively be referred to as a Iateral left direction.
    The insole 34 comprises an anterior arch support 48, a medial archsupport 50 and a Iateral arch support 52. Each of the anterior archsupport 48, the medial arch support 50 and the Iateral arch support 52 israised vertically with respect to the respective adjacent surfaces of the insole 34. ln this example, the anterior arch support 48 has a general droplet shapewhere the tip of the droplet points in the posterior direction 42. Theanterior arch support 48 is substantially centered in the Iateral direction46 of the insole 34. 14 160313SE The anterior arch support 48 has a maximum length in the longitudinaldirection of the insole 34 that is approximately 20% of the length of theinsole 34 in the longitudinal direction 40. Moreover, the anterior archsupport 48 has a maximum length in the width direction (i.e. in thelateral direction 46) of the insole 34 that is approximately 50%, of thelocal width of the insole 34 in the lateral direction 46 where the anteriorarch support 48 is provided. Moreover, the anterior arch support 48 ispositioned with its geometrical center point at a distance from a front tipof the insole 34 that is approximately 40% of the longitudinal length of the insole 34.
    As can be seen in Fig. 3, each of the medial arch support 50 and thelateral arch support 52 has a generally arch shaped appearance with aninwardly pointing arc. Each of the anterior arch support 48, the medialarch support 50 and the lateral arch support 52 is successively vertically raised with respect to the respective adjacent surface of the insole 34.
    The medial arch support 50 has a length in the longitudinal direction 40of the insole 34 that is approximately 48% of the length of the insole 34in the longitudinal direction 40. The lateral arch support 52 has a lengthin the longitudinal direction 40 of the insole 34 that is approximately 53% of the length of the insole 34 in the longitudinal direction 40.
    Each of the medial arch support 50 and the lateral arch support 52 ispositioned with its geometrical center point at a distance from a front tipof the insole 34 that is approximately 63% of the longitudinal length ofthe insole 34. The anterior arch support 48, the medial arch support 50and the lateral arch support 52 of this implementation comprises a shock absorbing material.
    Fig. 4 schematically represents a bottom view of the insole 34 and Fig. 5schematically represents a top view of the insole 34 and where hiddenreinforcing bridges are illustrated with dashed lines. With collectivereference to Figs. 4 and 5, the insole 34 comprises an anterior reinforcing bridge 54. The anterior reinforcing bridge 54 comprises a raised section 15 160313SE 56 for providing rigidity, strength and compression resistance to the anterior arch support 48 over time. ln this implementation, the anterior reinforcing bridge 54 has anelongated appearance and extends substantially in the |atera| direction46 of the insole 34. The anterior reinforcing bridge 54 is positioned withits geometrical center point at a distance from a front tip of the insole 34that is approximately 39% of the longitudinal length of the insole 34.Furthermore, the anterior reinforcing bridge 54 has a width in thelongitudinal direction 40 of the insole 34 that is approximately 4% of the longitudinal length of the insole 34 and/or approximately 10 mm.
    The insole 34 further comprises two transverse reinforcing bridges 58,60. Each transverse reinforcing bridge 58, 60 has two raised sections 62for providing resistance against compression of the medial arch support50 and the |atera| arch support 52, respectively. The transversereinforcing bridges 58, 60 thus adds rigidity to the medial arch support50 and the |atera| arch support 52 and contributes to maintaining theoriginal shape of the medial arch support 50 and the |atera| arch support52 over time. Moreover, the two transverse reinforcing bridges 58,60 prevent the insole 34 from bending about a central longitudinal axis.
    Each of the two transverse reinforcing bridges 58, 60 has an elongatedappearance and extends substantially in the |atera| direction 46 of theinsole 34. The first anterior transverse reinforcing bridge 58 is positionedwith its geometrical center point at a distance from the front tip of theinsole 34 that is approximately 57% of the longitudinal length of theinsole 34. The second posterior transverse reinforcing bridge 60 ispositioned with its geometrical center point at a distance from a front tipof the insole 34 that is approximately 70% of the longitudinal length ofthe insole 34. Each of the two transverse reinforcing bridges 58,60 has awidth in the longitudinal direction 40 of the insole 34 that isapproximately 4% of the longitudinal length of the insole 34 and/or approximately 10 mm. 16 160313SE The insole 34 further comprises two substantially parallel obliquereinforcing bridges 64, 66 inclined with respect to the longitudinal axis 40of the insole 34. Each of the oblique reinforcing bridges 64, 66 has anelongated appearance and extends at an angle with respect to thelongitudinal axis 40 of the insole 34 from a posterior, medial point to ananterior Iateral point of the insole 34 at an angle with respect to the longitudinal direction 40 of the insole 34 that is approximately 37°.
    The anterior oblique reinforcing bridge 64 extends from a posterior pointof the medial arch support 50 to an anterior point of the Iateral archsupport 52. The posterior oblique reinforcing bridge 66 also extends froma posterior point of the medial arch support 50 to an anterior point of theIateral arch support 52. Each oblique reinforcing bridge 64, 66 has a width of approximately 10 mm.
    Each oblique reinforcing bridge 64, 66 comprises two raised sections 68for providing resistance against compression of the medial arch support50 and/or the Iateral arch support 52. However, one or both of the oblique reinforcing bridge 64, 66 may only comprise one raised section 68 or no raised section 68.
    The two oblique reinforcing bridges 64, 66 add rigidity to the medial archsupport 50 and the Iateral arch support 52 and contribute to maintainingthe original shape of the medial arch support 50 and the Iateral archsupport 52 over time. Moreover, the two oblique reinforcing bridges 64, 66 prevent the insole 34 from twisting about the longitudinal axis 40.
    The oblique reinforcing bridges 64,66 are connected to the transversereinforcing bridges 58, 60 at their crossing areas. The anterior obliquereinforcing bridge 64 is connected to the anterior reinforcing bridge 54 attheir crossing area. As an alternative to connecting the reinforcingbridges 54, 58, 60, 64, 66, all or some of the reinforcing bridges 54,58,60 64, 66, may be integrally formed. The reinforcing bridges 54, 58, 60 64, 66, may constitute a bridge layer. A bottom layer may cover the 17 160313SE reinforcing bridges 54, 58, 60, 64, 66. A damping layer may further be provided between a top layer and the bridge layer.
    Fig. 6a schematically represents an anterior view of an anteriorreinforcing bridge 54. As can be seen, the raised section 56 of theanterior reinforcing bridge 54 is raised in the vertical direction 32. Theraised section 56 of this anterior reinforcing bridge 54 has a generally arcshaped appearance and spans over substantially the entire width of the insole 34.
    Fig. 6b schematically represents an anterior view of an alternativeanterior reinforcing bridge 54. The raised section 56 of this anteriorreinforcing bridge 54 only spans over a partial distance (e.g. a centralsection) of the width of the insole 34. Here, the raised section 56 is anintermediate raised section 56 of the anterior reinforcing bridge 54arranged between two further substantially straight sections 70 of theanterior reinforcing bridge 54. ln this implementation, the intermediateraised section 56 has a length in the lateral direction 46 that isapproximately 50% of the local lateral width of the insole 34 where the anterior reinforcing bridge 54 is provided.
    Each of the anterior reinforcing bridges 54 in Figs. 6a and 6b is convex asseen in the anterior direction 40 of the insole 34. ln theseimplementations, the anterior reinforcing bridge 54 has a substantially downwardly directed cavity and a substantially upwardly directed bulge.
    Fig. 7a schematically represents an anterior view of an anteriortransverse reinforcing bridge 58 and/or a posterior transverse reinforcingbridge 60. The transverse reinforcing bridge 58, 60 is concave as seen inthe anterior direction 40 of the insole 34 and has a substantially upwardlydirected cavity and a substantially downwardly directed bulge. Thetransverse reinforcing bridge 58, 60 thus has a continuous concave arcshape. ln this case, the two ends of the arc shape constitutes the respective raised sections 62 of the transverse reinforcing bridges 58, 60. 18 160313SE Fig. 7b schematically represents an anterior view of an alternativetransverse reinforcing bridge 58, 60. Also this design may be used for ananterior transverse reinforcing bridge 58 and/or a posterior transversereinforcing bridge 60.
