Description

La présente invention a pour objet un chausson de danse.The present invention relates to a dance shoe.

Les chaussons de danse sont fabriqués depuis de très nombreuses années, mais les exigences des utilisateurs s'affinent et il convient de résoudre les problèmes que posent les chaussons de type connu afin de les rendre plus performants.Dance shoes have been manufactured for many years, but user requirements are becoming more refined and the problems posed by known type shoes need to be resolved in order to make them more efficient.

A haut niveau, les utilisateurs ont besoin d'un grand nombre de paires de chaussons, lors des entraînements mais également lors des représentations, si bien que la consommation annuelle de certains utilisateurs peut atteindre la centaine de chaussons par an. Compte tenu de la fabrication très délicate et précise de ces chaussons, on comprend que les budgets pour chausser certains danseurs ou danseuses deviennent très importants.At high level, users need a large number of pairs of slippers, during training but also during performances, so that the annual consumption of certain users can reach a hundred of slippers per year. Given the very delicate and precise manufacture of these slippers, it is understandable that the budgets for fitting certain dancers become very important.

Un chausson de danse comprend essentiellement une partie chaussante en toile recouverte d'un tissu extérieur, généralement en satin, une semelle extérieure et une semelle intérieure en matériau biocompatible, ainsi qu'un bout dur à la pointe du chausson pour permettre à l'utilisateur de se mettre en position sur pointes.A dance shoe essentially comprises a canvas footwear part covered with an outer fabric, generally in satin, an outer sole and an inner sole made of biocompatible material, as well as a hard toe at the tip of the shoe to allow the user to get into position on spikes.

Cette conception de chausson est très ancienne et n'a que très peu évolué.This shoe design is very old and has changed very little.

La semelle intérieure pose un premier problème. Celle-ci est généralement réalisée en carton, recouvert d'un tissu ou d'un matériau, à base de fibres agglomérées en non tissé, commercialisé sous la dénomination "texon" tous deux biocompatibles. La semelle intérieure comporte à sa partie inférieure généralement un renfort en carton également, dont la forme et la dimension sont adaptées au poids et/ou à la forme du pied de l'utilisateur. Cet ensemble de la semelle intérieure et du renfort est collé directement sur la semelle extérieure, en emprisonnant, entre les deux, les plis et coutures de la partie chaussante inférieure.The insole poses a first problem. This is generally made of cardboard, covered with a fabric or a material, based on agglomerated fibers in nonwoven, sold under the name "texon" both biocompatible. The insole also generally has a cardboard reinforcement at its lower part, the shape and size of which are adapted to the weight and / or the shape of the user's foot. This set of insole and reinforcement is glued directly on the outsole, trapping, between the two, the folds and seams of the lower fitting.

Le problème posé par ce type de semelle est sa déformation très rapide. En effet, on comprend que le carton qui compose le renfort n'est pas un matériau élastique mais un matériau plastique, si bien que dès qu'il est déformé et cassé il ne reprend plus sa position initiale. Ainsi, dès que l'utilisateur a effectué quelques positions sur pointes la semelle et son renfort sont définitivement déformés. Ces mises sur pointes répétées "cassent" la semelle qui ne joue plus aucun rôle et n'assure plus le soutien du pied de l'utilisateur durant cette position sur pointes qui est en elle-même une position très fatigante et délicate. La perte d'élasticité du renfort de la semelle intérieure augmente la fatigue de l'utilisateur, ce qui pourrait être préjudiciable à la qualité de ses mouvements. Aussi, les utilisateurs à haut niveau sont-ils amenés à changer très fréquemment de chaussons, y compris durant une même représentation.The problem with this type of sole is its very rapid deformation. Indeed, we understand that the cardboard that makes up the reinforcement is not an elastic material but a plastic material, so that as soon as it is deformed and broken it no longer returns to its initial position. Thus, as soon as the user has made a few positions on points, the sole and its reinforcement are permanently deformed. These repeated spikes "break" the sole which no longer plays any role and no longer ensures the support of the foot of the user during this position on spikes which is in itself a very tiring and delicate position. The loss of elasticity of the reinforcement of the insole increases user fatigue, which could be detrimental to the quality of its movements. Also, high-level users are required to change slippers very frequently, including during the same performance.

De même, le bout du chausson présente plusieurs inconvénients. Il convient de distinguer dans ce bout deux parties, l'une dite bout dur qui est l'extrémité avant du chausson et l'empeigne qui est la partie qui remonte du bout dur sur la partie chaussante.Similarly, the end of the boot has several drawbacks. It is advisable to distinguish in this end two parts, one known as hard end which is the front end of the liner and the vamp which is the part which goes up from the hard end on the fitting part.

Le bout dur proprement dit des chaussons existants est réalisé à partir de toile de jute imprégnée de colle et conformé sur des modèles. Cet ensemble de toile de jute imprégnée de colle est également recouvert de satin, comme l'ensemble du chausson. Les bouts durs ainsi réalisés se déforment notamment dans la géométrie initiale qui leur est donnée et l'extrémité parfaitement plate du chausson devient, assez vite, sensiblement ronde. Surtout l'angle pré-déterminé entre la semelle et le bout dur s'affaisse au point de devenir arrondi, ce qui rend plus difficile la montée sur pointes et surtout plus délicate la stabilité dans cette position sur pointes.The actual hard end of the existing slippers is made from burlap impregnated with glue and shaped on models. This set of burlap impregnated with glue is also covered with satin, like the whole of the slipper. The hard ends thus produced are deformed in particular in the initial geometry which is given to them and the perfectly flat end of the liner quickly becomes appreciably round. Especially the predetermined angle between the sole and the toe sags to the point of becoming rounded, which makes it more difficult to climb on points and above all more stable in this position on points.

D'autre part, les chaussons ainsi réalisés sont relativement glissants puisque le satin est directement en contact avec la surface de travail, généralement du parquet.On the other hand, the slippers thus produced are relatively slippery since the satin is directly in contact with the work surface, generally parquet.

Enfin, les bouts durs existants présentent l'inconvénient d'être bruyants lorsque l'utilisateur se déplace sur les pointes, ce qui provoque des désagréments surtout dans certaines situations de calme parfait avec un très petit nombre d'utilisateurs ou bien dès lors qu'il y a de nombreux utilisateurs simultanément sur les pointes.Finally, existing hard ends have the disadvantage of being noisy when the user moves on the tips, which causes inconvenience especially in certain situations of perfect calm with a very small number of users or when there are many users simultaneously on the spikes.

L'autre partie du bout, c'est-à-dire l'empeigne, pose également des problèmes. En effet, lorsque l'utilisateur se met sur pointes, son pied doit être tenu par l'empeigne et la semelle de façon que l'empeigne et la semelle forment un entonnoir dans lequel l'extrémité du pied de l'utilisateur vient se bloquer, afin d'éviter que les orteils viennent au contact de l'extrémité du chausson, c'est-à-dire afin d'éviter que le poids de l'utilisateur vienne se concentrer sur ses seuls orteils. On constate là encore une déformation relativement rapide de l'empeigne, ce qui oblige les utilisateurs de haut niveau à un changement fréquent de chaussons.The other part of the tip, that is, the upper, is also problematic. Indeed, when the user stands on spikes, his foot must be held by the vamp and the sole so that the vamp and the sole form a funnel in which the end of the user's foot is blocked. , in order to prevent the toes from coming into contact with the end of the bootie, that is to say in order to prevent the user's weight from coming to concentrate on his only toes. Here again, there is a relatively rapid deformation of the upper, which requires high-level users to frequently change their slippers.

Dans le cas contraire, il se produit des déformations irréversibles des orteils et plus généralement de l'extrémité du pied.Otherwise, there is irreversible deformation of the toes and more generally of the end of the foot.

Sur les chaussons connus, les utilisateurs ont été amenés à constater un effet inesthétique sur la partie arrière du chausson au droit du talon. En effet, dans la position de marche normale, le chausson est parfaitement tendu et épouse la forme du pied, tandis que le passage sur pointes provoque une poche, au droit du talon, qui résulte d'un changement de forme du pied.On known slippers, users have been led to observe an unsightly effect on the part back of liner to right of heel. In fact, in the normal walking position, the liner is perfectly stretched and follows the shape of the foot, while the passage on points causes a pocket, in line with the heel, which results from a change in shape of the foot.

La présente invention a pour objet un chausson qui pallie ces inconvénients et qui permet de conserver à la semelle intérieure toute son élasticité facilitant ainsi les mouvements de l'utilisateur, qui présente un bout dur amortisseur de bruit, indéformable, qui prolonge la durée de vie du tissu extérieur de recouvrement et le rend antidérapant, qui présente une empeigne indéformable de façon à assurer un maintien périphérique du pied, et qui permet d'éviter la formation de poche au droit du talon.The subject of the present invention is a bootie which overcomes these drawbacks and which makes it possible to retain all of its elasticity in the insole, thus facilitating the movements of the user, which has a hard, noise-absorbing, non-deformable tip which prolongs the service life. of the outer covering fabric and makes it non-slip, which has a non-deformable upper so as to provide peripheral support for the foot, and which makes it possible to avoid pocket formation at the right of the heel.

Le chausson de danse selon l'invention comprend une partie chaussante en toile recouverte d'un tissu extérieur généralement en satin, une semelle extérieure et une semelle intérieure en matériau biocompatible ainsi qu'un bout à la pointe du chausson caractérisé en ce que la semelle intérieure comprend un renfort en un matériau déformable élastiquement. Ce matériau selon un mode de réalisation de l'invention est en polymère et plus particulièrement en polycarbonate.The dance shoe according to the invention comprises a canvas foot part covered with an outer fabric generally made of satin, an outer sole and an inner sole made of biocompatible material as well as an end at the tip of the boot characterized in that the sole inner includes a reinforcement in an elastically deformable material. This material according to an embodiment of the invention is made of polymer and more particularly of polycarbonate.

Selon l'invention, la forme et les épaisseurs sont étudiées en fonction des caractéristiques intrinsèques de l'utilisateur de façon que le renfort travaille uniquement dans le domaine élastique. Selon une autre caractéristique également la largeur du renfort est sensiblement égale à celle de la semelle, seule l'épaisseur étant variable.According to the invention, the shape and the thicknesses are studied as a function of the intrinsic characteristics of the user so that the reinforcement works only in the elastic domain. According to another characteristic also, the width of the reinforcement is substantially equal to that of the sole, only the thickness being variable.

Selon une autre caractéristique de l'invention, le chausson se caractérise par un bout dur comportant au moins une toile imprégnée d'au moins une résine durcissante.According to another characteristic of the invention, the liner is characterized by a hard toe comprising at least one fabric impregnated with at least one hardening resin.

Selon un mode de réalisation particulier, le chausson comprend plusieurs toiles superposées, dont les longueurs sont variables de façon à se prolonger progressivement le long de l'empeigne.According to a particular embodiment, the boot includes several superimposed fabrics, the lengths of which are variable so as to extend gradually along the upper.

Selon une caractéristique, le chausson comprend une couche de matériau absorbant les chocs, disposée sur la toile externe du bout dur, sous le tissu extérieur.According to one characteristic, the liner comprises a layer of shock absorbing material, disposed on the outer fabric of the hard toe, under the outer fabric.

Selon une autre caractéristique de l'invention, le tissu extérieur de recouvrement est imprégné sur la partie correspondant au bout dur également d'une résine durcissante.According to another characteristic of the invention, the outer covering fabric is impregnated on the part corresponding to the hard end also with a hardening resin.

Le chausson selon l'invention est également caractérisé en ce qu'il comprend une portion en tissu élastique à l'arrière du chausson sensiblement au droit du talon.The boot according to the invention is also characterized in that it comprises a portion of elastic fabric at the back of the boot substantially at the right of the heel.

La présente invention est décrite ci-après selon un mode de réalisation préférentiel en regard des dessins annexés sur lesquels :

  • la figure 1 représente une vue en coupe d'un chausson suivant un plan vertical médian selon l'invention,
  • les figures 2A et 2B représentent une vue de détail de la semelle du chausson, vue de dessous et de côté,
  • la figure 3 représente une vue de détail du bout du chausson, et
  • la figure 4 représente une vue de détail du talon du chausson.
The present invention is described below according to a preferred embodiment with reference to the accompanying drawings in which:
  • FIG. 1 represents a sectional view of a liner along a median vertical plane according to the invention,
  • FIGS. 2A and 2B represent a detailed view of the sole of the bootie, seen from below and from the side,
  • FIG. 3 represents a detailed view of the end of the liner, and
  • Figure 4 shows a detail view of the heel of the boot.

Sur la figure 1, on a représenté un chausson vu en coupe, qui comprend un bout 10, une semelle extérieure 12, une semelle intérieure 14 et une partie chaussante 16. Le bout se décompose en deux parties : le bout dur 18 et l'empeigne 20. Ainsi que cela est représenté, l'ensemble est recouvert d'une couche de tissu de recouvrement 21, généralement du satin, tandis qu'à l'intérieur, comme cela est représenté plus en détail sur la figure 3, on retrouve une couche de mousse 22 susceptible d'absorber les chocs et d'amortir les bruits, puis à l'intérieur une première couche 24 de toile imprégnée d'une résine afin de rendre le bout dur 18 parfaitement rigide et de conserver la géométrie initiale, notamment l'angle 26 de liaison entre le bout plat 28 d'extrémité et la partie 30 située dans le prolongement des semelles.In FIG. 1, a liner seen in section is shown, which comprises a toe 10, an outer sole 12, an inner sole 14 and a fitting part 16. The end breaks down into two parts: the hard end 18 and the vamp 20. As shown, the assembly is covered with a layer of covering fabric 21, generally satin, while inside , as shown in more detail in FIG. 3, there is a layer of foam 22 capable of absorbing shocks and absorbing noise, then inside a first layer 24 of canvas impregnated with a resin so to make the hard end 18 perfectly rigid and to keep the initial geometry, in particular the angle 26 of connection between the flat end end 28 and the part 30 located in the extension of the soles.

La couche 24 peut être complétée par une autre couche 32, également imprégnée d'une résine. Ces différentes couches, tant le nombre que les résines utilisées, sont choisies de façon à éventuellement conférer au bout 18 une rigidité progressive au fur et à mesure que l'on remonte le long de l'empeigne 20.The layer 24 can be completed by another layer 32, also impregnated with a resin. These different layers, both the number and the resins used, are chosen so as to possibly give the end 18 a progressive rigidity as one goes up along the upper 20.

De façon à éviter que la résine ne puisse couler, on interpose en fabrication entre les différentes couches, des feuilles d'étanchéité, par exemple en Nylon (marque déposée).In order to prevent the resin from leaking, sealing sheets, for example made of nylon (registered trademark), are interposed in the manufacturing between the different layers.

De plus, le chausson comprend une doublure de confort intérieure.In addition, the liner includes an interior comfort lining.

En ce qui concerne le prolongement des toiles imprégnées de résine le long de l'empeigne, il convient d'apprécier en fonction de la morphologie du pied et des caractéristiques intrinsèques de l'utilisateur les dimensions de la partie imprégnée de l'empeigne et les profils devant constituer la coque de maintien du pied en position sur pointes.With regard to the extension of the fabrics impregnated with resin along the vamp, it is advisable to assess according to the morphology of the foot and the intrinsic characteristics of the user the dimensions of the impregnated part of the vamp and the profiles to constitute the shell for holding the foot in position on points.

De plus, le bout dur 18 est également renforcé par imprégnation du satin à l'aide d'une résine, cette opération pouvant être réalisée une fois le chausson fini et le polymère, plus exactement un élastomère, doit être résistant à l'abrasion, doit être également doté de caractéristiques d'amortissement des bruits et vibrations et suffisamment imprégnable pour pénétrer à l'intérieur des fibres du satin et en même temps il doit avoir des qualités antidérapantes. Un tel élastomère peut être par exemple du polyuréthane.In addition, the hard end 18 is also reinforced by impregnating the satin with a resin, this operation can be carried out once the liner finished and the polymer, more exactly an elastomer, must be resistant to abrasion, must also be endowed with noise and vibration damping characteristics and sufficiently impregnable to penetrate inside the fibers of the satin and at the same time it must have non-slip qualities. Such an elastomer may for example be polyurethane.

De façon connue, la partie chaussante 16 comprend à sa partie supérieure un galon 34 dans lequel coulisse un lacet 36, permettant d'assurer le serrage et l'adaptation du chausson sur le pied. De façon connue, la partie chaussante comprend une toile, généralement de la toile de coton, recouverte extérieurement de satin, comme l'ensemble du chausson. La partie arrière de cette partie chaussante, dans une vue de détail représentée sur la figure 4, est complétée selon l'invention par une pièce 38 en matériau élastique qui vient se substituer à l'association toile plus satin, au droit du talon. Ce tissu peut également être du satin élastique, c'est-à-dire des fibres naturelles ou artificielles tissées avec des fibres élastiques.In known manner, the footwear part 16 comprises at its upper part a braid 34 in which a lace 36 slides, making it possible to tighten and adapt the bootie to the foot. In known manner, the footwear part comprises a canvas, generally cotton canvas, externally covered with satin, like the whole of the bootie. The rear part of this footwear part, in a detail view represented in FIG. 4, is completed according to the invention by a part 38 made of elastic material which replaces the combination of canvas plus satin, in line with the heel. This fabric can also be elastic satin, that is to say natural or artificial fibers woven with elastic fibers.

La semelle extérieure 12 du chausson représenté est généralement réalisée en cuir et il s'agit là d'une semelle qui doit être en contact avec le sol. Les chaussons de bonne qualité utilise le cuir qui a de bonnes qualités d'amortissement mécanique, mais aussi des qualités d'amortissement du bruit, ainsi que des qualités antidérapantes. Cette semelle extérieure court sensiblement sur une longueur correspondant à celle de la plante du pied. Cette semelle est posée sur l'ensemble des différentes couches de tissu et sur les coutures, si bien qu'elle assure, en même temps, un effet esthétique de masquage à la partie inférieure.The outer sole 12 of the boot shown is generally made of leather and this is a sole which must be in contact with the ground. Good quality slippers use leather which has good mechanical damping qualities, but also noise damping qualities, as well as non-slip qualities. This outsole runs substantially over a length corresponding to that of the sole of the foot. This sole is placed on all the different layers of fabric and on the seams, so that it ensures, at the same time, an aesthetic effect of masking to the lower part.

Plus exactement, les différentes couches de tissu sont emprisonnées entre cette semelle extérieure 12 et la semelle intérieure 14.More precisely, the different layers of fabric are trapped between this outer sole 12 and the inner sole 14.

Cette semelle intérieure 14 comprend une couche de matière biocompatible 40 qui est directement en contact avec le pied, cette couche pouvant être en carton surmonté d'un tissu de coton ou bien en cuir ou bien encore en un matériau, à base de fibres agglomérées en non tissé, commercialisé sous la dénomination "texon", qui présente des qualités de biocompatibilité et notamment d'antisudation.This insole 14 comprises a layer of biocompatible material 40 which is directly in contact with the foot, this layer being able to be made of cardboard topped with a cotton fabric or leather, or even of a material, based on fibers agglomerated in nonwoven, sold under the name "texon", which has qualities of biocompatibility and in particular of antiperspiration.

Sous cette couche 40 de la semelle intérieure, il est prévu un renfort 42 qui est collé directement sur la couche 40 de matériau biocompatible et qui confère à l'ensemble du chausson toutes ses qualités mécaniques. Ce renfort est découpé, dans le mode de réalisation préféré de l'invention, suivant une forme sensiblement identique à celle de la semelle et d'épaisseur variable en fonction des caractéristiques de l'utilisateur. Ce renfort est réalisé en un matériau déformable élastiquement et son épaisseur est telle que, compte tenu des caractéristiques intrinsèques de l'utilisateur, il ne travaille que dans le domaine élastique en évitant tout effort qui pourrait le conduire à travailler dans le domaine plastique.Under this layer 40 of the insole, a reinforcement 42 is provided which is bonded directly to the layer 40 of biocompatible material and which gives the whole of the liner all of its mechanical qualities. This reinforcement is cut, in the preferred embodiment of the invention, in a shape substantially identical to that of the sole and of variable thickness depending on the characteristics of the user. This reinforcement is made of an elastically deformable material and its thickness is such that, taking into account the intrinsic characteristics of the user, it only works in the elastic domain while avoiding any effort which could lead it to work in the plastic domain.

Un tel renfort est réalisé de façon préférentielle en polycarbonate collé sur la couche de matériau biocompatible d'une part et collé ensuite sur la semelle extérieure 12 de façon à prendre les différentes extrémités des différentes couches de toile de la partie chaussante et du bout en sandwich entre les semelles intérieure et extérieure, cette dernière ayant été préalablement cousue sur les tissus.Such reinforcement is preferably made of polycarbonate bonded to the layer of biocompatible material on the one hand and then bonded to the outer sole 12 so as to take the different ends of the different layers of fabric from the footwear part and from the sandwich toe between the inner and outer soles, the latter having been previously sewn onto the fabrics.

Un renfort, au moyen d'un rivet, permet d'améliorer cette liaison mécanique des semelles intérieure, extérieur et du renfort.A reinforcement, by means of a rivet, makes it possible to improve this mechanical connection of the inner, outer soles and of the reinforcement.

Un tel chausson présente de nombreux avantages puisque son bout, réalisé à partir de satin imprégné d'une résine, a une usure moindre du fait de la résistance de ce composite à l'usure, mais présente en même temps des qualités d'amortissement du bruit et évite tout dérapage, compte tenu de son bon coefficient de frottement et de plus, confère au bout dur une géométrie constante et évite toute détérioration de la forme initialement donnée. L'interposition d'une couche de mousse ou d'un matériau absorbant les chocs tel qu'un élastomère permet de compléter l'amortissement du bruit et des chocs et évite la transmission des vibrations dans tout le corps de l'utilisateur, ce qui lui confère également un confort accru.Such a bootie has many advantages since its tip, made from satin impregnated with a resin, has less wear due to the resistance of this composite to wear, but at the same time exhibits damping qualities of the noise and avoids any skidding, taking into account its good coefficient of friction and moreover, gives the hard end a constant geometry and avoids any deterioration of the shape initially given. The interposition of a layer of foam or shock absorbing material such as an elastomer makes it possible to complete the damping of noise and shock and prevents the transmission of vibrations throughout the body of the user, which also gives it increased comfort.

Quant à l'empeigne, elle est améliorée du fait des différentes couches de toile et des différentes résines d'imprégnation, qui lui assurent une conservation parfaite de la forme initiale, ce qui permet de maintenir le pied de l'utilisateur par coincement dans une forme sensiblement tronconique, évite tout élargissement qui conduirait à un glissement du pied vers le bas, notamment en position sur pointes, ce qui aurait comme désagrément de faire reposer l'utilisateur sur ses doigts de pied, voire provoquer des blessures graves ou des déformations osseuses.As for the vamp, it is improved due to the different layers of canvas and the different impregnation resins, which ensure that it retains its original shape perfectly, which makes it possible to hold the user's foot by wedging it in a substantially frustoconical shape, avoids any enlargement which would lead to a sliding of the foot down, in particular in position on spikes, which would have the annoyance of making the user rest on his toes, even causing serious injuries or bone deformations .

De façon plus intéressante et très recherchée par les utilisateurs, la semelle intérieure et son renfort en matériau à déformation élastique confèrent un avantage immédiat qui est celui de maintenir constantes les qualités du chausson au fur et à mesure de l'utilisation, puisque les qualités élastiques du matériau ne sont jamais altérées, si bien que la "nervosité" de la semelle reste constante, au fur et à mesure de l'utilisation.More interestingly and much sought after by users, the insole and its reinforcement made of elastic deformation material give an immediate advantage which is that of maintaining the qualities of the booties are constant as they are used, since the elastic qualities of the material are never altered, so that the "nervousness" of the sole remains constant, as they are used.

Qui plus est, la réalisation d'un tel renfort conduit à des effets induits non négligeables. En effet, le danseur, lorsqu'il repose sur sa semelle extérieure 12, le pied à plat, effectue de nombreuses variations et le fait que la semelle a un renfort quasiment de la même largeur augmente la stabilité de l'utilisateur, notamment lorsqu'il est sur un seul pied et à plat, puisque le renfort n'est pas localisé.What is more, the production of such a reinforcement leads to non-negligible induced effects. Indeed, the dancer, when he rests on his outer sole 12, the foot flat, makes many variations and the fact that the sole has a reinforcement of almost the same width increases the stability of the user, especially when it is on one foot and flat, since the reinforcement is not localized.

Il est entendu que, dans certains cas, le renfort peut présenter des nervures positionnées de façon adéquate, afin de renforcer l'élasticité de telle ou telle partie de la semelle, mais de façon générale il est possible de jouer simplement sur l'épaisseur du matériau et de découper ces renforts directement dans des plaques de matériau d'épaisseur variable.It is understood that, in certain cases, the reinforcement may have ribs suitably positioned, in order to reinforce the elasticity of such or such part of the sole, but in general it is possible to simply play on the thickness of the material and cut these reinforcements directly from sheets of material of variable thickness.

Un tel renfort permet d'obtenir une progressivité très intéressante qui est étudiée en fonction de la courbure que doit prendre le pied.Such reinforcement makes it possible to obtain a very interesting progressiveness which is studied as a function of the curvature that the foot must take.

Ainsi, le renfort peut se prolonger très en arrière, pratiquement sous le talon, sans pour cela gêner le bon positionnement du pied.Thus, the reinforcement can extend far back, practically under the heel, without hampering the correct positioning of the foot.
