Abstract

The boot, e.g. for mountaineering, skiing and other snow sports, consists of a sole (10) and an upper (2) which has a hole (22) at the top for inserting the foot. The front portion of the upper is closed by a tongue (25) which has a gusset (23) on each side connecting it to the main part of the upper to prevent anything from penetrating between the two sides of the boot once it is laced up. The lacing holes/hooks extend from the toe of the boot to the very top of its leg section, which is lines with an elastic foam material.

Description

La présente invention a pour objet une chaussure de sport et plus spécifiquement une chaussure devant assurer une double fonction de tenue de pied et de protection de celui-ci vis à vis d'éléments extérieurs tels que pluie, neige, cailloux,..., telle qu'une chaussure de marche destinée à la marche en montagne et haute montagne, ou encore une chaussure de ski de fond ou de ski de randonnée, télémark, surf des neiges (snowboard),...etc.The subject of the present invention is a sports shoe and more specifically a shoe which has to perform a dual function of holding the foot and protecting it from external elements such as rain, snow, stones, etc., such as a walking shoe intended for walking in the mountains and in the high mountains, or even a cross-country skiing or ski touring shoe, telemark, snowboard (snowboard), ... etc.

Traditionnellement, les chaussures de montagne ou de ski de randonnée, télémark,...etc, sont des chaussures robustes, à tige montante et en cuir épais de façon à assurer une bonne tenue du pied et de la cheville sur tout type de terrain, notamment en éboulis et devers, et un bon contrôle de l'organe de glisse dans le cas d'une chaussure de ski, télémark, surf,...etc.Traditionally, mountain or ski touring boots, telemark, ... etc, are robust shoes, with an uppers and thick leather to ensure good foot and ankle grip on all types of terrain, particularly in scree and slopes, and good control of the sliding member in the case of a ski boot, telemark, surf, ... etc.

Ces chaussures présentent toutefois l'inconvénient d'être lourdes, peu confortables et difficiles à lacer autour du pied du fait de la rigidité du matériau employé.However, these shoes have the drawback of being heavy, not very comfortable and difficult to tie around the foot due to the rigidity of the material used.

Il est également connu, plus particulièrement pour la marche sur glacier, d'utiliser des chaussures dites à coque plastique, c'est à dire des chaussures dont la tige est en matériau synthétique rigide. De telles chaussures comportent par ailleurs un chausson interne généralement amovible destiné à assurer le confort du pied à l'intérieur de la chaussure.It is also known, more particularly for glacier walking, to use so-called plastic shell shoes, that is to say shoes whose upper is made of rigid synthetic material. Such shoes also include a generally removable internal bootie intended to ensure the comfort of the foot inside the shoe.

Dans ce cas, le pied est tenu par l'intermédiaire du chausson, par la déformation de la coque mettant sous contrainte ce dernier.In this case, the foot is held via the liner, by the deformation of the shell putting stress on the latter.

Outre la difficulté de déformer la coque plastique afin d'assurer le serrage souhaité, ce type de chaussure présente également l'inconvénient que tout mouvement relatif du chausson par rapport à la coque ne peut être exclus, sauf à déformer très fortement la coque sur le chausson et générer ainsi de fortes pressions et de l'inconfort sur le pied.In addition to the difficulty of deforming the plastic shell in order to ensure the desired tightening, this type of shoe also has the disadvantage that any relative movement of the liner relative to the shell cannot be excluded, except to very strongly deform the shell on the liner and thus generate strong pressure and discomfort on the foot.

Il est également connu, par exemple par le FR 2 678 487 de réaliser une chaussure de marche comprenant à l'intérieur d'une tige externe un dispositif de serrage du pied destinée à assurer la tenue du pied à l'intérieur de la chaussure, indépendamment de la tige externe, qui elle n'assure qu'une fonction de protection vis à vis des conditions extérieures.It is also known, for example from FR 2 678 487, to produce a walking shoe comprising, inside an external upper, a device for tightening the foot intended to ensure the holding of the foot inside the shoe, independently of the external rod, which only provides a protective function against external conditions.

Dans cette chaussure, la tige externe est munie sur le dessus du pied d'une ouverture longitudinale s'étendant depuis la cheville jusqu'au bout de pied, et fermée soit par une fermeture à glissière, soit par des moyens auto-agrippants.In this shoe, the outer upper is provided on the top of the foot with a longitudinal opening extending from the ankle to the end of the foot, and closed either by a zipper or by hook-and-loop means.

Une telle chaussure permet effectivement une tenue de pied et un confort à l'intérieur de la chaussure nettement améliorés.Such a shoe effectively allows a significantly improved foot hold and comfort inside the shoe.

Cependant, l'ouverture longitudinale de la tige externe sur le dessus du pied est préjudiciable à l'étanchéité de l'ensemble.However, the longitudinal opening of the outer rod on the top of the foot is detrimental to the tightness of the assembly.

Ces chaussures connues présentent également l'inconvénient de permettre peu de sensations proprioceptives pour le pied du fait de la rigidité des matériaux employés pour la tige.These known shoes also have the drawback of allowing few proprioceptive sensations for the foot due to the rigidity of the materials used for the upper.

Le but de la présente invention est de remédier à ces inconvénients et de fournir une chaussure de sport/marche/montagne/ski perfectionnée, et notamment une chaussure offrant une tenue de pied et une étanchéité améliorées tout en restant la plus légère possible, et en offrant de bonnes caractéristiques de sensations proprioceptives.The aim of the present invention is to remedy these drawbacks and to provide an improved sports / walking / mountain / ski shoe, and in particular a shoe offering improved footing and sealing while remaining as light as possible, and by offering good characteristics of proprioceptive sensations.

Ce but est atteint dans la chaussure de sport selon l'invention qui est du type comportant un dispositif de serrage interne disposé au niveau du cou-de-pied, et une tige externe de protection contre les agressions extérieures munie d'une ouverture pour le passage du pied et de moyens de fermeture de cette ouverture, par le fait que l'ouverture de la tige externe est uniquement disposée à l'extrémité supérieure de celle-ci, et que la tige externe présente à l'avant une structure complètement fermée, munie d'au moins un soufflet permettant une ouverture de la tige autorisant le passage d'un pied, les moyens de fermeture de l'ouverture de la tige étant constitués par un laçage disposé au-dessus du soufflet.This object is achieved in the sports shoe according to the invention which is of the type comprising an internal tightening device disposed at the instep, and an external rod for protection against external aggressions provided with an opening for the passage of the foot and of means for closing this opening, by the fact that the opening of the external rod is only disposed at the upper end thereof, and that the external rod has a completely closed structure at the front , provided with at least one bellows allowing an opening of the rod authorizing the passage of a foot, the means for closing the opening of the rod being constituted by a lacing disposed above the bellows.

En effet, la suppression de l'ouverture longitudinale sur tout l'avant du pied existant dans les chaussures connues permet d'augmenter de façon considérable l'étanchéité de la chaussure, et, par ailleurs, il a été fait la constatation non évidente à priori qu'une telle construction de tige n'était pas incompatible avec l'utilisation d'un dispositif de serrage interne, et que l'ouverture de la tige autorisée par le soufflet était suffisante pour permettre l'accès au dispositif de serrage interne.Indeed, the elimination of the longitudinal opening over the entire front of the foot existing in known shoes makes it possible to considerably increase the tightness of the shoe, and, moreover, it has been made the not obvious observation to a priori that such a rod construction was not incompatible with the use of an internal clamping device, and that the opening of the rod authorized by the bellows was sufficient to allow access to the internal clamping device.

Une construction de chaussure étanche et légère est ainsi obtenue puisque le dispositif de serrage interne au moyen de quartiers de serrage est beaucoup moins lourd qu'un dispositif de serrage interne à double tige ou chausson intérieur.A waterproof and lightweight shoe construction is thus obtained since the internal tightening device by means of tightening quarters is much lighter than an internal tightening device with double rod or inner boot.

Selon un mode de réalisation avantageuse, le laçage de la tige externe s'étend depuis l'extrémité supérieure de celle-ci jusqu'au niveau du bout de pied, de ce fait, le laçage de la tige externe peut également être utilisé comme moyen supplémentaire de tenue de pied à l'intérieur de la chaussure.According to an advantageous embodiment, the lacing of the external rod extends from the upper end thereof to the level of the toe, therefore the lacing of the external rod can also be used as a means additional foot support inside the shoe.

Selon un mode de réalisation préférée, la paroi intérieure de la tige est doublée d'un matériau en mousse élastique, au moins sur la partie avant pied de la chaussure, de façon à obtenir lors du laçage de la tige externe un contact du pied avec la mousse, sans aucune compression des parties en contact du pied.According to a preferred embodiment, the inner wall of the upper is lined with an elastic foam material, at least on the forefoot part of the shoe, so as to obtain, when lacing the external upper, contact of the foot with the foam, without any compression of the parts in contact with the foot.

En effet, il a été constaté que ce simple contact du pied avec la mousse apportait une sensibilité proprioceptive particulièrement appréciable pour la pratique de l'escalade puisque renseignant sur l'équilibration, le positionnement et le déplacement du corps.Indeed, it was found that this simple contact of the foot with the foam brought a proprioceptive sensitivity particularly appreciable for the practice of climbing since providing information on the balance, positioning and movement of the body.

Enfin, selon un autre mode de réalisation, les moyens de serrage des quartiers de serrage interne sont constitués par un lacet reliant les deux quartiers par l'intermédiaire d'éléments de renvoi disposé sur ces quartiers, et par un bloqueur disposé à l'extrémité libre du lacet. De ce fait, le serrage interne du pied est encore facilité malgré l'ouverture limitée de la tige puisqu'il suffit d'exercer une traction sur l'extrémité libre du lacet jusqu'à l'obtention de la tension de serrage souhaitée, et ensuite de bloquer le lacet dans la position obtenue à l'aide du bloqueur de lacet.Finally, according to another embodiment, the means for tightening the internal tightening quarters are constituted by a lace connecting the two quarters by means of return elements disposed on these quarters, and by a blocker disposed at the end. free of the lace. As a result, the internal tightening of the foot is further facilitated despite the limited opening of the upper since it suffices to exert traction on the free end of the lace until the desired tightening tension is obtained, and then lock the lace in the position obtained using the lace blocker.

De toute façon, l'invention sera mieux comprise et d'autres caractéristiques de celle-ci seront mises en évidence à l'aide de la description qui suit en référence au dessin schématique annexé en illustrant un mode de réalisation préféré, et dans lequel :

  • la figure 1 est une vue en perspective de 3/4 avant avec arraché partiel d'une chaussure selon l'invention,
  • la figure 2 est une vue de côté de la chaussure de la figure 1,
  • la figure 3 est une vue similaire à la figure 2 d'une chaussure selon un autre mode de réalisation.
In any case, the invention will be better understood and other characteristics thereof will be highlighted with the aid of the description which follows with reference to the appended schematic drawing illustrating a preferred embodiment, and in which:
  • FIG. 1 is a perspective view of 3/4 front with a partial cutaway of a shoe according to the invention,
  • FIG. 2 is a side view of the shoe of FIG. 1,
  • Figure 3 is a view similar to Figure 2 of a shoe according to another embodiment.

Ainsi que le montre la figure 1, la chaussure de sport et plus particulièrement de marche, selon l'invention, est constituée d'une semelle externe dite de marche 10, d'une tige externe 20 et d'un dispositif de serrage interne 30.As shown in FIG. 1, the sports shoe and more particularly the walking shoe, according to the invention, consists of an external sole called a walking shoe 10, an external upper 20 and an internal tightening device 30 .

Le dispositif de serrage interne est, de façon connue en soi, constitué de deux quartiers ou bandes de serrage 31 en un matériau flexible et disposés au niveau de la partie cou-de-pied de la chaussure.The internal tightening device is, in a manner known per se, made up of two quarters or tightening strips 31 made of a flexible material and arranged at the instep part of the shoe.

Chaque quartier de serrage 31 est fixé, de façon connue en soi, par son extrémité inférieure 32 au bord inférieur de la chaussure, en l'occurrence entre la semelle externe 10 et la première de montage (non représentée sur le dessin).Each clamping quarter 31 is fixed, in a manner known per se, by its lower end 32 to the lower edge of the shoe, in this case between the outer sole 10 and the first mounting (not shown in the drawing).

Cette extrémité inférieure 32 de chacun ou de l'un seulement des quartiers de serrage peut également être fixée à un niveau différent en hauteur sur la tige afin d'obtenir par exemple un serrage du pied plutôt du côté interne ou médial de la chaussure, ou pour tenir compte d'impératifs de montage de la tige/chaussure.This lower end 32 of each or only one of the tightening quarters can also be fixed at a different level in height on the upper in order to obtain, for example, a tightening of the foot rather on the internal or medial side of the shoe, or to take into account the mounting requirements of the upper / shoe.

Par ailleurs, le bord arrière 33 de chaque quartier de serrage 31 est fixé très loin à l'arrière de la chaussure, au niveau du talon 2 de celle-ci, comme montré à la figure 2, de façon à obtenir une tenue de pied optimum vers l'arrière, et éviter un glissement du pied vers l'avant lors des descentes.Furthermore, the rear edge 33 of each tightening quarter 31 is fixed very far to the rear of the shoe, at the heel 2 thereof, as shown in FIG. 2, so as to obtain a foot hold. optimum towards the rear, and avoid sliding the foot forward during descents.

Le bord avant 34 s'étend quant à lui au niveau de la limite inférieure de la zone du cou-de-pied appelée généralement bas de cou-de-pied.The front edge 34 extends in turn to the level of the lower limit of the area of the instep generally called the instep.

Comme le montre particulièrement la figure 2, chaque quartier de serrage 31 comporte à son bord libre supérieur 35 une série de passants ou éléments de renvoi 36 pour un lacet 37.As shown particularly in FIG. 2, each clamping quarter 31 has at its upper free edge 35 a series of loops or return elements 36 for a lace 37.

Dans l'exemple représenté, chaque passant 36 est constitué par une sangle repliée en forme de boucle. Un tel mode de réalisation présente l'avantage d'une construction avec surépaisseur minimale, et est donc adapté pour un serrage par la tige externe sans création de surpressions ou points durs au niveau de ces passants.In the example shown, each pass 36 is constituted by a strap folded in the form of a loop. Such an embodiment has the advantage of a construction with minimum excess thickness, and is therefore suitable for tightening by the external rod without creating overpressures or hard points at these passers-by.

Selon le mode de réalisation ou l'usage envisagé, ces passants peuvent également être remplacés par des boucles métalliques, crochets,...etc.Depending on the embodiment or the intended use, these passers-by can also be replaced by metal loops, hooks, ... etc.

Selon un mode de construction préféré, le lacet 37 est passé alternativement sur chacun des quartiers de serrage 31, et est ancré par chacune de ses extrémités libres 38 au dernier passant 36 situé au niveau du bord avant 34 de chaque quartier de serrage 31.According to a preferred construction method, the lace 37 is passed alternately over each of the clamping quarters 31, and is anchored by each of its free ends 38 to the last loop 36 located at the front edge 34 of each clamping quarter 31.

Le lacet 37 définit alors, à l'extrémité opposée aux points d'ancrage 38, une boucle fermée 39 constituant un élément de préhension et de traction pour le serrage des quartiers de serrage 31.The lace 37 then defines, at the end opposite to the anchoring points 38, a closed loop 39 constituting a gripping and traction element for tightening the tightening quarters 31.

Un tel mode d'ancrage est particulièrement avantageux car la boucle 39 constitue un élément de préhension unique permettant d'exercer un effort de traction symétrique sur chacun des brins du lacet.Such an anchoring method is particularly advantageous since the loop 39 constitutes a single gripping element making it possible to exert a symmetrical tensile force on each of the strands of the lace.

Par ailleurs, un bloqueur de lacet 40 monté coulissant sur les brins du lacet dans la zone de la boucle 39 permet de bloquer ces brins dans la position de serrage souhaitée.Furthermore, a lace blocker 40 slidably mounted on the strands of the lace in the area of the loop 39 allows these strands to be locked in the desired tightening position.

Bien entendu, le lacet 37 pourrait également être monté de façon classique avec la boucle 39 placée à l'extrémité inférieure du laçage et le bloqueur de lacet 40 disposé sur les extrémités libres du lacet, une telle construction présentant cependant l'inconvénient d'un risque de serrage dissymétrique.Of course, the lace 37 could also be mounted in a conventional manner with the loop 39 placed at the lower end of the lacing and the lace blocker 40 disposed on the free ends of the lace, such a construction however having the drawback of risk of asymmetrical tightening.

Dans les deux cas, le système de serrage à l'aide d'un bloqueur est particulièrement intéressant car l'effort de serrage peut être exercé par une seule main, l'utilisateur n'ayant ensuite qu'à déplacer à l'aide de son autre main le bloqueur jusqu'à la position souhaitée.In both cases, the clamping system using a blocker is particularly advantageous since the clamping force can be exerted with one hand, the user then only having to move using his other hand the blocker to the desired position.

Par ailleurs, l'utilisation d'un tel système de serrage à bloqueur de lacet est particulièrement intéressante dans le cadre de l'utilisation dans un espace restreint à l'intérieur d'une tige fermée.Furthermore, the use of such a clamping system with a lace blocker is particularly advantageous in the context of use in a limited space inside a closed rod.

Enfin, le bloqueur peut être réalisé de façon particulièrement plane sans création de surépaisseur susceptible de créer des zones de contraintes ou surpressions sur le pied.Finally, the blocker can be produced in a particularly flat manner without creating any extra thickness capable of creating stress zones or overpressures on the foot.

Une languette 41 est prévue, de façon connue en soi, sous le dispositif de serrage interne de façon à éviter les surpressions au niveau du cou-de-pied.A tongue 41 is provided, in a manner known per se, under the internal clamping device so as to avoid overpressures at the instep.

Cette languette 41 est fixée à l'extrémité avant de la chaussure, de façon connue en soi, par une couture 42.This tongue 41 is fixed to the front end of the shoe, in a manner known per se, by a seam 42.

Dans l'exemple de réalisation, cette couture 42 est recouverte par une bande en caoutchouc 43 entourant la tige, de façon à en garantir l'étanchéité.In the embodiment, this seam 42 is covered by a rubber band 43 surrounding the rod, so as to guarantee the seal.

On notera que la fixation de la languette 41 à une certaine distance des quartiers de serrage interne permet d'utiliser celle-ci comme levier pour desserrer le lacet 37.It will be noted that the fixing of the tongue 41 at a certain distance from the internal tightening quarters makes it possible to use the latter as a lever for loosening the lace 37.

La tige externe 20 de la chaussure est de préférence réalisée en une seule pièce, comme dans l'exemple représenté de façon à éliminer toutes les coutures pouvant nuire à l'étanchéité globale de la chaussure.The external upper 20 of the shoe is preferably made in one piece, as in the example shown so as to eliminate all the seams which could affect the overall tightness of the shoe.

Comme le montre plus particulièrement la figure 2, la tige 20 ne présente qu'une seule ouverture 22 disposée uniquement à son extrémité supérieure 21. Afin de définir un passage néanmoins suffisant pour la mise en place du pied à l'intérieur de la chaussure, la tige comporte sur sa partie verticale avant deux soufflets 23 de forme sensiblement triangulaire fermant l'ouverture traditionnellement ménagée entre les quartiers latéraux 24 et la claque avant 25.As shown more particularly in FIG. 2, the upper 20 has only one opening 22 disposed only at its upper end 21. In order to define a passage which is nevertheless sufficient for the positioning of the foot inside the shoe, the rod has on its front vertical part two bellows 23 of substantially triangular shape closing the opening traditionally formed between the lateral quarters 24 and the front flap 25.

La tige 20 a donc une structure fermée, mise à part l'ouverture du haut 22, et donc extrêmement étanche.The rod 20 therefore has a closed structure, apart from the top opening 22, and therefore extremely sealed.

Les soufflets 23, de préférence en matériau plus souple que le reste de la tige de façon à permettre un "repliage" facile de celle-ci, autorisent donc une large ouverture du haut de la tige 22 pour le passage du pied.The bellows 23, preferably made of a more flexible material than the rest of the rod so as to allow easy "folding" of the latter, therefore allow a wide opening from the top of the rod 22 for the passage of the foot.

Une fois le pied en place, la tige peut être repliée, comme montré à la figure 1, et assujettie autour du pied.Once the foot in place, the rod can be folded up, as shown in Figure 1, and secured around the foot.

Comme le montre plus particulièrement la figure 2, la tige 20 et notamment sa claque avant 25, est conçue avec suffisamment d'ampleur pour que son ouverture 22 s'étende sensiblement jusqu'à l'aplomb en direction verticale des bords inférieurs 34 des quartiers de serrage 31. De cette façon est garanti un accès aisé jusqu'à l'extrémité inférieure du laçage du dispositif de serrage interne.As shown more particularly in FIG. 2, the rod 20 and in particular its front flap 25, is designed with sufficient width so that its opening 22 extends substantially up to the vertical alignment of the lower edges 34 of the quarters clamping 31. This guarantees easy access to the lower end of the lacing of the internal clamping device.

La tige 20 comporte par ailleurs un système de serrage par laçage 26 constitué d'éléments de renvoi 27, tels que crochets, boucle, et d'un lacet 28 qui s'étend non seulement sur la partie verticale de la tige, mais aussi sur tout le dessus de pied jusqu'au bout 3 de la chaussure.The rod 20 furthermore comprises a lacing clamping system 26 consisting of return elements 27, such as hooks, loop, and a lace 28 which extends not only over the vertical part of the rod, but also over the entire top of the foot to the tip 3 of the shoe.

Ce laçage 26 permet non seulement de "fermer" l'ouverture 22 autour de la jambe, mais également de serrer la tige 20 autour du pied.This lacing 26 makes it possible not only to "close" the opening 22 around the leg, but also to tighten the rod 20 around the foot.

On obtient donc un double serrage interne/externe permettant d'augmenter notablement la tenue et les sensations du pied.We thus obtain a double internal / external tightening allowing to significantly increase the holding and the sensations of the foot.

Ainsi, le serrage interne permet plus particulièrement de solidariser le pied à la semelle de la chaussure, et donc d'avoir un contact plus direct avec le sol, et par conséquent "moins de jeu", une meilleure transmission et sensation des informations venant du sol, et, de façon surprenante, l'impression d'avoir d'une chaussure beaucoup plus légère car "répondant" tout de suite.Thus, the internal tightening more particularly makes it possible to secure the foot to the sole of the shoe, and therefore to have more direct contact with the ground, and therefore "less play", better transmission and feeling of information coming from the ground, and, surprisingly, the impression of having a shoe much lighter because "responding" immediately.

La tige externe apporte quant à elle une protection du pied vis à vis des éléments extérieurs (eau/neige/froid/chocs), et est réalisée dans un des matériaux appropriés à une telle fonction (par exemple cuir...). Dans le cas d'une chaussure de ski, snowboard,...etc, cette tige pourra également comporter des renforts appropriés aux transmissions des efforts, prises d'appui,...etc, se produisant dans ce type de sport.The outer rod provides protection for the foot against external elements (water / snow / cold / shocks), and is made of one of the materials suitable for such a function (for example leather ...). In the case of a ski boot, snowboard, etc., this rod may also include reinforcements suitable for the transmission of forces, grips, etc., occurring in this type of sport.

Enfin, le serrage externe permet un ajustement précis du volume extérieur de la tige autour du pied et est donc particulièrement intéressant pour l'obtention de sensations proprioceptives renseignant sur l'équilibre, le positionnement ou le déplacement du corps. De telles sensations proprioceptives sont particulièrement recherchées dans le cas de sports de glisse ou sports tels que l'escalade.Finally, the external tightening allows a precise adjustment of the external volume of the rod around the foot and is therefore particularly advantageous for obtaining proprioceptive sensations providing information on the balance, positioning or movement of the body. Such proprioceptive sensations are particularly sought in the case of sliding sports or sports such as climbing.

Afin d'augmenter cet effet de sensations proprioceptives, la paroi intérieure de la tige 20 peut être doublée d'un matériau en mousse élastique, tel que du polyuréthane, au moins sur la partie avant pied de la chaussure qui correspond à une partie du pied présentant une excellente sensibilité proprioceptive. Un tel doublage en mousse permet en effet de garantir lors du laçage de la tige externe un ajustement extrêmement précis de celle-ci au contact du pied sans pour autant provoquer de quelconques points de compressions sur le pied, la mousse permettant de compenser les différences de volume liées à l'anatomie et permettant donc d'obtenir le contact tige-pied le plus étroit possible.In order to increase this effect of proprioceptive sensations, the inner wall of the upper 20 can be lined with an elastic foam material, such as polyurethane, at least on the forefoot part of the shoe which corresponds to a part of the foot. with excellent proprioceptive sensitivity. Such a foam lining in fact makes it possible to guarantee when lacing the outer rod an extremely precise adjustment of the latter in contact with the foot without however causing any points of compression on the foot, the foam making it possible to compensate for the differences in volume linked to the anatomy and thus making it possible to obtain the closest stem-foot contact possible.

De préférence, un tel doublage mousse sera réalisé sur toute la surface intérieure de la tige, et sera d'une épaisseur adaptée à l'utilisation souhaitée.Preferably, such a foam lining will be produced over the entire inner surface of the rod, and will be of a thickness suitable for the desired use.

La figure 3 montre une chaussure présentant les mêmes caractéristiques que la chaussure de la figure 2, mis à part le dispositif de serrage interne. Les mêmes éléments seront donc désignés par les mêmes références. Dans ce cas, le serrage interne 30 est également constitué de deux quartiers de serrage 31 disposés au niveau de la partie cou-de-pied de la chaussure.Figure 3 shows a shoe having the same characteristics as the shoe of Figure 2, apart from the internal tightening device. The same elements will therefore be designated by the same references. In this case, the internal clamping 30 also consists of two clamping quarters 31 arranged at the instep part of the shoe.

La différence réside dans le fait que le bord arrière 33a de chaque quartier de serrage 31 s'étend de façon plus verticale par rapport au bord arrière 33 des quartiers de serrage de l'exemple précédent.The difference lies in the fact that the rear edge 33a of each clamping quarter 31 extends more vertically with respect to the rear edge 33 of the clamping quarters of the previous example.

Dans un tel cas, la tenue de pied vers l'arrière ou tenue talon est fournie par une bande 35a sensiblement horizontale reliant les deux bords supérieurs 35 de chaque quartier de serrage en formant une sorte de chaînage autour du talon.In such a case, the rear foot hold or heel hold is provided by a substantially horizontal band 35a connecting the two upper edges 35 of each tightening quarter by forming a kind of chaining around the heel.

Bien entendu, la présente invention n'est pas limitée aux modes de réalisation décrits ci-avant à titre d'exemples non limitatifs, et n'est notamment pas limitée à une application chaussure de marche, mais peut également être étendue à tout autre type de chaussure et notamment tout autre chaussure pour la pratique de sports de glisse.Of course, the present invention is not limited to the embodiments described above by way of nonlimiting examples, and is in particular not limited to a walking shoe application, but can also be extended to any other type. shoe and in particular any other shoe for the practice of sliding sports.
