    Slipper ballet shoe. The invention comprises the application of composite materials and other materials and a new structure to improve its performance, increase comfort, minimize damage to the feet, and increase the life of the shoe. Different coatings of the interior of the soul, the incorporation of gel bags located in the metatarsal area and in the heel, and on the outside of PORON, elastic satin and suede, improve the comfort, fit, and performance of the shoe. The contributions of this design will lengthen the life in use of the product, which unlike the current burlap used, will ensure a greater number of cycles. Although it is adaptable to each dancer due to the malleability of its materials, it is universal and does not need external elements to achieve full comfort, ensuring a better response during its use.

    [0001]
    [0002] Slipper ballet shoe.
    [0003]
    [0004] Sector of the technique
    [0005]
    [0006] The present invention consists in the improvement and updating of the traditional ballet tips slippers, replacing the current traditional design by a new more industrial approach with materials with better features.
    [0007]
    [0008] State of the art
    [0009]
    [0010] The shoes are the main tool of a ballet dancer, since most of the technique is based on steps, choreography and training wearing this type of footwear.
    [0011]
    [0012] The shoes should be strong enough to hold the dancers pointed, but also malleable enough to allow the dancers to perform movements that articulate through the intrinsic muscles and joints of the foot and ankle.
    [0013]
    [0014] The first time some tips are released, they have a soul so rigid that there are dancers who use different methods to "break" them and thus soften the area of the tip or stylize the foot with the shoe on. the continued work and the sweat of the foot comes at a time when the box and the soul of the tip are too soft to dance.
    [0015] Sneakers vary in strength and stiffness, although dancers do not necessarily choose their shoes based solely on these two characteristics. They also choose, based on comfort, their adjustment to the foot, the weight, the flexibility in the half tip and the aesthetics facing the outside.
    [0016]
    [0017] There are different patents of ballet slippers that, to a greater or lesser extent, try to correct some of the problems that dancers encounter. The most relevant are described below.
    [0018]
    [0019] US7900375 B2. A new concept is described here as far as internal protective material of the tip is concerned. This protection absorbs the impacts generated during the dance, preventing them from being transmitted directly to the fingers. Soft and flexible material that varies its stiffness through intelligent molecules, which react instantly when there is an impact to offer cushioning and support.
    [0020]
    [0021] US20100126042 A1. The invention of a shoe is described, not exclusively designed for classical ballet, where the box and the template are joined through an articulated joint. This design helps the dancer to perform the half point, making the metatarsal area more flexible and gaining in durability, stability and absorption of impacts. The division in different parts, allows the interchangeability of pieces, allowing the personalization of the shoe according to the needs through the different modules.
    [0022]
    [0023] US6895693 B2. Division in two of the external stencil of the shoe that comes into contact with the ground. Specially designed to dance on tips, the free space of the template in the central part, allows a greater flexibility of the foot, helping the movement of the half tip. The interior template also has a reduced length, increasing flexibility and gaining lightness with the decrease in weight. Combination of materials to favor the movement and lightness of the templates.
    [0024] US5035069 A. Integral manufacture of the interior of the shoe from a flexible thermoplastic polymer material, which can be adjusted by the dancer to adapt it to the foot. The box of the fingers is connected to the template through a minimally curved joint that favors aesthetics and flexibility. This skeleton is covered by a layer of shock absorbing material, absorbing the impacts of the dance. The outer platform of the box, as well as the template, are lined with a non-slip material that is sustainable over time.
    [0025]
    [0026] US1704281 A. Reinforcement stitched for ballet shoes in the area of the fingers, through the superposition of layers. Provides wear resistance and sustainability over time.
    [0027] US1689535 A. Toe protector for the pointed shoe, which has as its object the absorption of impacts during the dance. Simplicity and efficiency are present in this layered design, with economical and durable manufacturing in use.
    [0028]
    [0029] US1520708 A. The object of the present invention is the incorporation of a protective intermediate layer between the cover and the skeleton of the shoe, which provides cushioning to reduce the noise of the shoe when hitting the ground and lengthens the life of the shoe to the add a more resistant material in the area of the platform, which prevents the tearing of the outer satin.
    [0030]
    [0031] US5101579 A. Inserting a layer of flexible foam material into the platform of the tip box. This material, soundproofs the impact of the tip on the floor during the dance and makes the area subject to more fatigue during the use of the product more resistant.

    [0038]
    [0039] CN108459081 DE102011016946. Application of PORON to footwear, without direct application to ballet shoes.
    [0040]
    [0041] US2011265348. Patent corresponding to the design of a tip protection for the ballet shoe, personalized by a material that with the use of a catalyst generates a mold for each person.
    [0042]
    [0043] Explanation of the invention
    [0044]
    [0045] It is ballet tip shoes with a new structure and composition, manufactured with the application of new materials. Carbon fiber, fiberglass and aramid composite material is used from prepregs for the manufacture of the interior structure of the ballet tip shoes. The sole and the tip are integrated into a single piece called the soul, with areas of different thicknesses and compositions. Coatings of other materials are included to improve the properties and durability of the same, as well as to increase the comfort of the dancer. The use of these materials will suppose a remarkable increase of the life in use of the current product, assuring a better behavior in a greater number of cycles. The selection of material composed of zones, its orientation and the number of layers, will allow to better adapt the product according to its function requires greater flexibility, hardness or resistance to impact, thus favoring the natural movement of the dancer. Other components and layers of material in different areas of the shoes complete the invention, providing foot protection, improved performance and avoiding discomfort and damage to the dancer.

    [0096] Embodiment of the invention
    [0097]
    [0098] The proposed ballet shoe design (Figure 1) consists of a core (1) that integrates the tip and the arch of the shoe, made of carbon fiber, fiberglass and hybrid carbon and aramid fiber, coated of transparent silicone and arranged in different layers (Fig. 7) that make up the base of the shoe. In this soul, different zones are distinguished (Figure 5) according to the different needs of rigidity, hardness and resistance to impacts. The design of the different zones is responsible for ensuring, according to the arrangement of the layers of fabric composed of hybrid fiber preimpregnated carbon and aramid, the composition of the same, the number of layers, and the addition of special resins (silicone) ) to soften the contours, the characteristics of flexibility or hardness that each zone requires for the optimal operation of the product and the comfort of the user.
    [0099]
    [0100] While in zone 2, metatarsal flexion seeks flexibility to favor the tip, both the toe (zone 5) and part of the box (zone 4) and the nerve (zone 1) will have a much more resistant finish and less flexible, ensuring the correct support of the body with these parts.
    [0101]
    [0102] To distribute the loads at the tip evenly (Fig. 6), a silicone accessory (10) covered by a layer of microperforated EVA rubber (9) is included. This accessory is housed inside the box of the soul, and allows to reduce the differences in tensions and pressures that support the toes, preventing injuries by overload and cushioning more impacts.
    [0103]
    [0104] The shoe (Fig. 1) is completed with a protector (2), rubber that is inserted inside the core, which incorporates an EVA rubber insole (3), with gel pockets permanently located in the areas of greater friction and pressure, heel and metatarsal area.
    [0105]
    [0106] The exterior of the core (1) is covered by a Poron® enclosure (4), for the absorption of impacts; This set, in turn, is covered with an elastic satin skin, which adapts to the shape of the shoe, and which is closed on the sole of the shoe by means of a chamois (6) acting as a sole. In assembly of the different parts can be seen in Figure 2.
    [0107]
    [0108] The elastic satin is fitted on the inside of the foot (Fig. 3) by means of additional elastic (7). The shoe is adjusted to the leg by a system of tapes that are integrated into the shoe through holes (8) to accommodate the tapes (fig.4).
