Abstract

The ski boot (1) comprises a sole (9) which is connected to the ski and a collar (4) pivoted on the heel (5) fixed to the sole, The axis (20) of the pivot (18) is situated in a longitudinal plane of the boot and oriented horizontally. The boot has asymmetric stops for limiting angular displacement of the collar. The collar has an internal lateral extension which fits in the lateral wall of the heel in order to limit outward angular displacement of the collar. This outward angular displacement of the collar is in a range between zero and 20 degrees. Zero displacement corresponds to the vertical position of the collar. Only the stops limit angular displacement of the collar towards the interior of the boot. The heel zone situated on the outside of the boot is higher than the zone situated on the interior side of the boot.

Description

La présente invention concerne une chaussure destinée au domaine des sports de glisse et particulièrement adaptée à la pratique du surf sur la neige ou "snow board".The present invention relates to a shoe intended for the field of sliding sports and particularly suitable for the practice of snowboarding or "snow boarding".

D'une manière générale, il est nécessaire d'apporter à un utilisateur, d'une part un certain confort, et d'autre part un maintien ou un guidage de certaines parties du pied ou de la jambe, pour lui permettre de prendre sans gêne des positions diverses en fonction des situations rencontrées en cours de glisse.In general, it is necessary to provide a user, on the one hand, a certain comfort, and on the other hand a support or a guidance of certain parts of the foot or of the leg, to allow him to take without embarrassment of various positions depending on the situations encountered during gliding.

Les positions de l'utilisateur sont corrélées à la technique généralement employée pour la pratique du sport de glisse.The user's positions are correlated with the technique generally used for the practice of board sports.

Dans le cas du surf, on peut de manière schématique assimiler un surf à une planche dont les deux côtés opposés situés dans le sens de la longueur permettent de prendre et de contrôler des appuis sur la neige.In the case of surfing, one can schematically assimilate a surf to a board whose two opposite sides located in the direction of the length make it possible to take and control supports on the snow.

L'utilisateur a les pieds solidarisés au surf, par l'intermédiaire de ses chaussures, de façon que les extrémités des pieds se situent à proximité d'un même côté et que les talons se situent à proximité du côté opposé.The user has the feet secured to the surf, through his shoes, so that the ends of the feet are close to the same side and the heels are close to the opposite side.

Les pieds de l'utilisateur sont donc orientés dans une direction sensiblement transversale du surf.The user's feet are therefore oriented in a substantially transverse direction of the surf.

Par conséquent, une prise de carre sur un côté longitudinal impose que la jambe soit bien maintenue par rapport au pied dans le sens de la longueur du pied. Il est nécessaire dans ce cas d'empêcher, ou au moins de limiter, un mouvement de flexion longitudinale de la jambe par rapport au pied.Therefore, an edge grip on a longitudinal side requires that the leg is well maintained relative to the foot in the direction of the length of the foot. In this case, it is necessary to prevent, or at least limit, a longitudinal flexion movement of the leg relative to the foot.

D'autre part, des variations d'inclinaison du relief ou des changements de direction amènent l'utilisateur à incliner ses jambes pour conserver un équilibre ou pour agir sur la conduite du surf.On the other hand, variations in slope of the relief or changes in direction cause the user to tilt his legs to maintain balance or to act on the conduct of the surf.

Généralement, l'inclinaison de la jambe se fait sensiblement dans le sens de la longueur du surf, c'est-à-dire latéralement par rapport au pied. Il est nécessaire dans ce cas que la jambe puisse s'incliner d'un côté ou de l'autre par rapport au pied.Generally, the inclination of the leg is substantially in the direction of the length of the surf, that is to say laterally relative to the foot. It is necessary in this case that the leg can tilt to one side or the other relative to the foot.

Les chaussures connues à l'heure actuelle peuvent être cassées dans deux catégories : celle des chaussures souples, qui sont alors associées à des fixations dites de type "coque" censées assurer les appuis nécessaires,et celle des chaussures rigides ou semi-rigides qui sont associées à des fixations de type "à boucle" coopérant uniquement avec la semelle à la manière des ensembles chaussure/fixation de ski alpin.The shoes known at present can be broken into two categories: that of flexible shoes, which are then associated with so-called "shell" type fastenings which are supposed to provide the necessary supports, and that of rigid or semi-rigid shoes which are associated with bindings of the "loop" type cooperating only with the sole in the manner of shoe / binding assemblies for downhill skiing.

Les chaussures souples permettent à la jambe de s'incliner dans tous les sens par rapport au pied, c'est-à-dire aussi bien dans une flexion longitudinale que latérale, ou encore dans une position qui combine ces deux sens d'inclinaison.Soft shoes allow the leg to tilt in all directions relative to the foot, that is, both in longitudinal and lateral flexion, or in a position that combines these two directions of inclination.

Ces chaussures ont l'inconvénient d'obliger l'utilisateur à fournir un effort important dans les prises de carre, pour maintenir le pied par rapport à la jambe. En effet, une prise de carre se fait sur un seul côté longitudinal. Le surf est alors en appui sur ce seul côté et c'est l'effort fourni par l'utilisateur qui le maintient dans la position voulue par rapport à la pente. Les muscles de la jambe sont très sollicités, ce qui fatigue rapidement l'utilisateur et le gêne considérablement. Par ailleurs, même si la fixation de type "coque" utilisée fournit une partie des appuis nécessaires, l'ensemble chaussure/fixation obtenu n'est jamais optimum, car :

  • les parties d'appui ou de transmission des efforts ne sont pas en contact direct avec l'ensemble pied/jambe, d'où une perte d'efficacité et défaut de précision,
  • les fixations ont une taille standard devant accomoder différentes tailles et largeurs de chaussure, d'où encore des appuis moins "francs" et une mauvaise adaptation à la morphologie de l'utilisateur,
  • les fixations à coque constituent sur la planche de sud un volume important rendant ce dernier difficile à transporter,
  • les fixations à coque multiplient les épaisseurs entre l'ensemble pied/jambe et la planche.
These shoes have the disadvantage of requiring the user to provide a significant effort in the grips of the edge, to maintain the foot relative to the leg. Indeed, an edge grip is done on one longitudinal side only. The surf is then supported on this single side and it is the effort provided by the user which keeps it in the desired position relative to the slope. The leg muscles are very stressed, which quickly tires the user and annoys him considerably. Furthermore, even if the fixing of type "shell" used provides some of the necessary support, the shoe / binding assembly obtained is never optimal, because:
  • the support or force transmission parts are not in direct contact with the foot / leg assembly, resulting in a loss of efficiency and lack of precision,
  • the bindings have a standard size which must accommodate different shoe sizes and widths, hence still less "frank" support and poor adaptation to the morphology of the user,
  • the hull fixings constitute a large volume on the south board making it difficult to transport,
  • the shell fasteners multiply the thicknesses between the foot / leg assembly and the board.

Les chaussures rigides ou semi-rigides connues comportent un collier qui entoure le bas de jambe et permet à l'utilisateur de maintenir sans fatigue son sud dans la position de prise de carre. Cependant, ces chaussures ne permettent pas la flexion latérale autour de la cheville, ce qui empêche l'utilisateur d'agir correctement pour conserver son équilibre ou conduire son sud. La rigidité de la chaussure oblige l'utilisateur à effectuer des mouvements d'amplitude exagérée, avec le buste et les bras, pour compenser le manque de mobilité latérale des jambes.Known rigid or semi-rigid shoes have a collar which surrounds the lower leg and allows the user to maintain his south without fatigue in the edge grip position. However, these shoes do not allow lateral flexion around the ankle, which prevents the user from acting correctly to maintain his balance or drive south. The rigidity of the shoe forces the user to carry out movements of exaggerated amplitude, with the bust and the arms, to compensate for the lack of lateral mobility of the legs.

Par conséquent, aucune des chaussures actuelles n'est complètement satisfaisante, dans la mesure où aucune ne permet à un utilisateur d'être à l'aise dans tous les cas de figures rencontrés dans la pratique du surf.Consequently, none of the current shoes is completely satisfactory, insofar as none allows a user to be comfortable in all cases encountered in the practice of surfing.

Le but de la présente invention est de remédier à ces inconvénients et de fournir une chaussure de sport de glisse et notamment sud, de type rigide/semi-rigide, améliorée, plus adaptée à la pratique du sud des neiges ou des sports de glisse mettant en oeuvre des mouvements similaires.The object of the present invention is to remedy these drawbacks and to provide a sliding and in particular southern sliding sport shoe, of the rigid / semi-rigid type, improved, more suited to the practice of southern snow or sliding sports putting implementing similar movements.

A cet effet, l'invention propose une architecture qui permet à un utilisateur de maîtriser, sans fatigue et sans douleur, les mouvements à exécuter pour la pratique de tels sports.To this end, the invention provides an architecture which allows a user to master, without fatigue and pain, the movements to be performed for the practice of such sports.

La chaussure selon l'invention comprend notamment une semelle rigide destinée à être liée à un organe de glisse ou surf, et un collier rigide articulé par un moyen de liaison sur une partie associée solidaire de la semelle, et est caractérisée en ce que le moyen de liaison est un pivot dont l'axe est situé dans un plan sensiblement longitudinal de la chaussure.The shoe according to the invention notably comprises a rigid sole intended to be linked to a sliding or surfing member, and a rigid collar articulated by a connecting means on an associated part integral with the sole, and is characterized in that the means connecting is a pivot whose axis is located in a substantially longitudinal plane of the shoe.

De plus, l'axe du pivot est, de préférence, orienté dans une direction sensiblement horizontale.In addition, the pivot axis is preferably oriented in a substantially horizontal direction.

Une telle chaussure résoud les problèmes de l'art antérieur en ce sens qu'elle permet un bon maintien longitudinal du pied par rapport à la jambe, tout en autorisant une inclinaison latérale de la jambe d'un côté ou de l'autre du pied, et en intégrant dans la chaussure les éléments d'appui nécessaires à la pratique du sport, pour une plus grande efficacité et un plus grand confort de l'utilisateur.Such a shoe solves the problems of the prior art in that it allows good longitudinal support of the foot relative to the leg, while allowing a lateral inclination of the leg on one side or the other of the foot. , and by integrating in the shoe the support elements necessary for the practice of sport, for greater efficiency and greater comfort for the user.

L'utilisateur peut donc exécuter tous les mouvements nécessaires à la pratique de son sport, sans fatigue anormale et sans gêne particulière.The user can therefore execute all the movements necessary for the practice of his sport, without abnormal fatigue and without particular discomfort.

D'autres caractéristiques et avantages de l'invention seront mieux compris à l'aide de la description qui va suivre, en regard du dessin annexé illustrant, à titre d'exemple non limitatif, comment l'invention peut être réalisée et dans lequel :

  • la figure 1 est une vue de trois-quarts arrière d'une chaussure selon l'invention,
  • la figure 2 est une vue de trois-quarts avant montrant notamment une coque et un collier, de la chaussure de la figure 1,
  • la figure 3 est une vue latérale de la chaussure de la figure 1,
  • la figure 4 est une coupe selon IV-IV de la figure 3,
  • la figure 5 est une vue similaire à la figure 4, où seuls la coque et le collier sont représentés,
  • la figure 6 est une vue similaire à la figure 5.
Other characteristics and advantages of the invention will be better understood with the aid of the description which follows, with reference to the appended drawing illustrating, by way of nonlimiting example, how the invention can be implemented and in which:
  • FIG. 1 is a rear three-quarter view of a shoe according to the invention,
  • FIG. 2 is a front three-quarter view showing in particular a shell and a collar, of the shoe of FIG. 1,
  • FIG. 3 is a side view of the shoe of FIG. 1,
  • FIG. 4 is a section on IV-IV of FIG. 3,
  • FIG. 5 is a view similar to FIG. 4, where only the shell and the collar are shown,
  • FIG. 6 is a view similar to FIG. 5.

La figure 1 montre une chaussure 1 destinée à la pratique du surf. Cette chaussure 1 comprend notamment une coque 2, une tige 3 et un collier 4.Figure 1 shows a shoe 1 for the practice of surfing. This shoe 1 notably comprises a shell 2, a rod 3 and a collar 4.

La coque 2 comprend un talon 5, une paroi latérale extérieure 6, une extrémité avant 7, une paroi latérale intérieure 8 non visible sur la figure 1, et une semelle 9 rigide destinée à coopérer avec un ensemble fixation de type à "boucle" connu en soi.The shell 2 comprises a heel 5, an external lateral wall 6, a front end 7, an internal lateral wall 8 not visible in FIG. 1, and a rigid sole 9 intended to cooperate with a known "buckle" type fastening assembly in itself.

Le talon 5, les parois 6 et 8 et l'extrémité 7 forment une ceinture relativement rigide. Cette ceinture est solidaire de la semelle 9 dont un relief arrière 10 et un relief avant 11 constituent des zones d'appui de la chaussure 1, sur le sol dans le cas de la marche, ou sur le surf dans le cas de la glisse.The heel 5, the walls 6 and 8 and the end 7 form a relatively rigid belt. This belt is integral with the sole 9, a rear relief 10 and a front relief 11 constituting support zones of the shoe 1, on the ground in the case of walking, or on the surf in the case of sliding.

La ceinture et la semelle 9 peuvent être fixées l'une par rapport à l'autre par tout moyen tel qu'un rivetage, un collage ou autre. La ceinture et la semelle 9 peuvent également former un ensemble monobloc obtenu par exemple par injection d'une matière plastique.The belt and the sole 9 can be fixed relative to each other by any means such as riveting, bonding or the like. The belt and the sole 9 can also form a one-piece assembly obtained for example by injection of a plastic material.

Dans tous les cas, la coque 2 obtenue par solidarisation de la ceinture et de la semelle 9 sera relativement rigide.In all cases, the shell 2 obtained by securing the belt and the sole 9 will be relatively rigid.

La coque 2 accueille la tige 3 qu'elle maintient grâce à la ceinture décrite précédemment. Il peut être prévu de coller la tige 3 dans la coque 2 pour éviter une désolidarisation de ces deux parties.The shell 2 receives the rod 3 which it maintains thanks to the belt described above. Provision may be made to stick the rod 3 in the shell 2 to avoid separation of these two parts.

La tige 3 qui est relativement souple recouvre au moins le dessus du pied et s'étend en hauteur pour entourer le bas de la jambe.The rod 3 which is relatively flexible covers at least the top of the foot and extends in height to surround the bottom of the leg.

La tige 3 est maintenue au contact du pied et du bas de jambe de l'utilisateur grâce à un moyen de fermeture 12 tel qu'un laçage, connu de l'homme de l'art.The rod 3 is kept in contact with the foot and the lower leg of the user by means of a closure means 12 such as a lacing, known to those skilled in the art.

Le collier 4, réalisé de préférence avec un matériau relativement rigide, entoure la partie supérieure 13 de la tige 3 et serre le bas de jambe de l'utilisateur, par un moyen de serrage et de fermeture 14 connu de l'homme du métier.The collar 4, preferably made with a relatively rigid material, surrounds the upper part 13 of the rod 3 and clamps the lower leg of the user, by a clamping and closing means 14 known to those skilled in the art.

Une poutre de rigidification 15 du collier 4 s'étend sensiblement verticalement de la partie supérieure 16 vers la partie inférieure 17 du collier 4.A stiffening beam 15 of the collar 4 extends substantially vertically from the upper part 16 towards the lower part 17 of the collar 4.

Cette poutre 15 peut être rapportée sur le collier 4 ou encore, selon un mode de construction préféré, la poutre 15 et le collier 4 peuvent former une pièce unique qui sera réalisée par exemple dans une matière plastique.This beam 15 can be attached to the collar 4 or, according to a preferred construction method, the beam 15 and the collar 4 can form a single piece which will be produced for example in a plastic material.

La poutre 15 permet l'articulation du collier 4 sur le talon 5 par un moyen de liaison tel qu'un pivot 18.The beam 15 allows the articulation of the collar 4 on the heel 5 by a connecting means such as a pivot 18.

Le pivot 18, symbolisé sur la figure 1 par un cercle, peut, selon un exemple non limitatif, être constitué par l'articulation dans un trou 19 du collier, d'un cylindre solidaire du talon 5.The pivot 18, symbolized in FIG. 1 by a circle, can, according to a nonlimiting example, be constituted by the articulation in a hole 19 of the collar, of a cylinder secured to the heel 5.

Le trou 19 est visible à la figure 2, sur laquelle seuls le collier 4 et la coque 2 ont été représentés en vue éclatée.The hole 19 is visible in Figure 2, in which only the collar 4 and the shell 2 have been shown in exploded view.

L'axe 20 du pivot 18 est situé dans un plan sensiblement longitudinal de la chaussure 1, de façon à permettre une inclinaison latérale du collier 4 par rapport à la coque 2, comme il sera décrit par la suite.The axis 20 of the pivot 18 is located in a substantially longitudinal plane of the shoe 1, so as to allow a lateral inclination of the collar 4 relative to the shell 2, as will be described later.

Selon un mode de réalisation préféré, l'axe 20 du pivot 18 est orienté dans une direction sensiblement horizontale. De ce fait, l'axe 20 est approximativement parallèle à la semelle 9, ce qui permet à la jambe de l'utilisateur d'être maintenue dans une position naturelle.According to a preferred embodiment, the axis 20 of the pivot 18 is oriented in a substantially horizontal direction. Therefore, the axis 20 is approximately parallel to the sole 9, which allows the user's leg to be held in a natural position.

En effet, une zone centrale 21 de la partie associée ou talon 5 solidaire de la semelle 9 coopère avec le collier 4 par la poutre de rigidification 15 pour servir de butée en direction longitudinale.Indeed, a central zone 21 of the associated part or heel 5 secured to the sole 9 cooperates with the collar 4 by the stiffening beam 15 to serve as a stop in the longitudinal direction.

Par conséquent, une flexion autour de la cheville du pied par rapport à la jambe n'est pas possible dans le sens longitudinal du pied.Therefore, bending around the ankle of the foot relative to the leg is not possible in the longitudinal direction of the foot.

L'utilisateur pourra donc facilement prendre appui sur les carres, puisqu'il n'a presque plus d'efforts à fournir pour conserver une position stable de la jambe par rapport au pied.The user can therefore easily lean on the edges, since he has almost no more effort to provide to maintain a stable position of the leg relative to the foot.

La figure 3, sur laquelle la chaussure 1 est vue du côté extérieur, permet de mieux comprendre encore le phénomène.Figure 3, in which the shoe 1 is seen from the outside, allows a better understanding of the phenomenon.

D'autre part, l'utilisateur aura de grandes facilités pour diriger son surf ou s'adapter aux sollicitations extérieures, car le pivot 18 permet des inclinaisons latérales du collier 4 comme il a été dit et comme il est montré à la figure 4.On the other hand, the user will have great facilities for directing his surfing or adapting to external stresses, since the pivot 18 allows lateral inclinations of the collar 4 as has been said and as shown in FIG. 4.

Pour ce faire, des moyens de butée limitent au moins dans un sens les déplacements angulaires du collier 4.To do this, stop means limit at least one direction the angular displacements of the collar 4.

De préférence, le collier 4 comporte un prolongement latéral intérieur 22 apte à coopérer avec une paroi latérale 23 du talon 5 pour limiter le déplacement angulaire du collier 4 vers l'extérieur.Preferably, the collar 4 has an internal lateral extension 22 capable of cooperating with a lateral wall 23 of the heel 5 to limit the angular displacement of the collar 4 towards the outside.

Le prolongement latéral intérieur 22 joue le rôle d'une butée en venant appuyer sur la paroi latérale 23 du talon 5.The internal lateral extension 22 acts as a stop by pressing on the lateral wall 23 of the heel 5.

Cette fonction est importante, car les positions prises par l'utilisateur par rapport au sud engendrent des inclinaisons de jambe vers l'intérieur qui sont très importantes, alors que les inclinaisons vers l'extérieur sont plus réduites.This function is important, because the positions taken by the user relative to the south cause inward leg inclinations which are very important, while the outward inclinations are more reduced.

C'est pourquoi les moyens de butée sont asymétriques : le prolongement latéral intérieur 22 du collier 4 s'étend pour couvrir la paroi latérale 23 du talon 5, alors qu'aucun prolongement ne part de la poutre de rigidification 15 pour s'étendre et couvrir une paroi latérale 24 du talon 5 située du côté extérieur de la chaussure.This is why the abutment means are asymmetrical: the internal lateral extension 22 of the collar 4 extends to cover the lateral wall 23 of the heel 5, while no extension leaves the stiffening beam 15 to extend and cover a side wall 24 of the heel 5 located on the outside of the shoe.

Le fonctionnement du moyen de butée constitué par le prolongement latéral intérieur 22 du collier 4 est représenté de manière schématique sur les figures 5 et 6.The operation of the abutment means constituted by the internal lateral extension 22 of the collar 4 is shown schematically in FIGS. 5 and 6.

La figure 5 correspond à une inclinaison du collier 4, par rapport à la coque 2, vers l'intérieur de la chaussure 1. Cette inclinaison se fait selon une valeur d'angle α qui varie entre 0 et 50 degrés. Elle correspond à une position de jambe qui transmet beaucoup d'informations sensitives à l'utilisateur, et c'est pour cela que le collier 4 n'est guidé par rapport à la coque 2 que par le pivot 18. Aucune butée ne limite le déplacement angulaire du collier 4 vers le côté intérieur de la chaussure, de façon à ne pas gêner l'utilisateur.FIG. 5 corresponds to an inclination of the collar 4, relative to the shell 2, towards the inside of the shoe 1. This inclination takes place according to an angle value α which varies between 0 and 50 degrees. It corresponds to a leg position which transmits a lot of sensitive information to the user, and that is why the collar 4 is only guided relative to the shell 2 by the pivot 18. No stopper limits the angular movement of the collar 4 towards the inner side of the shoe, so as not to disturb the user.

Par contre, comme il est représenté à la figure 6, il est utile que le prolongement latéral intérieur 22 limite le déplacement angulaire du collier 4 vers le côté extérieur de la chaussure 1, pour que l'utilisateur trouve un appui qui l'aidera à donner des efforts pour la conduite de son surf.On the other hand, as shown in FIG. 6, it is useful for the internal lateral extension 22 to limit the angular displacement of the collar 4 towards the external side of the shoe 1, so that the user finds a support which will help him to give efforts for the conduct of his surf.

Pour ce faire, le prolongement latéral intérieur 22 situé sur la partie inférieure 17 du collier 4 du côté intérieur de la chaussure 1, vient prendre appui sur la paroi latérale intérieure 23 du talon 5 de façon que le déplacement angulaire β du collier 4 vers l'extérieur se fait dans une plage comprise entre 0 et 20 degrés, le zéro correspondant à la position verticale du collier 4.To do this, the internal lateral extension 22 located on the lower part 17 of the collar 4 on the internal side of the shoe 1 comes to bear on the internal lateral wall 23 of the heel 5 so that the angular displacement β of the collar 4 towards the the exterior is in a range between 0 and 20 degrees, the zero corresponding to the vertical position of the collar 4.

En effet, lorsque le collier 4 est incliné vers l'extérieur dans le sens de la flêche F2, le prolongement latéral intérieur 22 du collier 4 est plaqué contre la paroi latérale intérieure 23 du talon 5, alors que lorsque le collier 4 est incliné vers l'intérieur dans le sens de la flêche F1, le prolongement latéral intérieur 22 est écarté du talon 5 et est donc inactif.In fact, when the collar 4 is inclined outwards in the direction of the arrow F2, the internal lateral extension 22 of the collar 4 is pressed against the internal lateral wall 23 of the heel 5, while when the collar 4 is inclined towards inside in the direction of arrow F1, the internal lateral extension 22 is spaced from the heel 5 and is therefore inactive.

Il est possible d'ajuster la valeur de l'inclinaison angulaire du collier 4 en modifiant la hauteur du talon 5. De préférence, le talon 5 est asymétrique et la zone du talon 5 située vers le côté extérieur de la chaussure 1 est plus haute que la zone située vers le côté intérieur de la chaussure 1, par rapport à la semelle 9.It is possible to adjust the value of the angular inclination of the collar 4 by modifying the height of the heel 5. Preferably, the heel 5 is asymmetrical and the area of the heel 5 situated towards the outside of the shoe 1 is higher. as the zone located towards the interior side of the shoe 1, relative to the sole 9.

Cela revient à dire que la paroi latérale extérieure 24 du talon 5 est plus haute que la paroi latérale intérieure 23, par rapport à la semelle 9.This amounts to saying that the outer lateral wall 24 of the heel 5 is higher than the inner lateral wall 23, relative to the sole 9.

Cette disposition permet d'une part comme on l'a vu d'assurer une fonction de butée vers l'extérieur de la chaussure 1, et facilite d'autre part un grand débattement vers le côté intérieur.This arrangement allows on the one hand as we have seen to ensure a stop function towards the outside of the shoe 1, and on the other hand facilitates a large clearance towards the inner side.

En effet, la tige 3 est soumise à une flexion latérale importante quand la jambe s'incline vers l'intérieur. La différence de hauteur des deux côtés du talon 5 favorise une flexion interne de la tige 3 sans détérioration de la chaussure 1.Indeed, the rod 3 is subjected to significant lateral bending when the leg tilts inward. The difference in height on the two sides of the heel 5 promotes internal flexion of the upper 3 without deterioration of the shoe 1.

Bien entendu, l'invention n'est pas limitée au mode de réalisation ainsi décrit, et comprend tous les équivalents techniques pouvant entrer dans l'étendue des revendications suivantes.Of course, the invention is not limited to the embodiment thus described, and includes all the technical equivalents which may fall within the scope of the following claims.

Elle n'est notamment pas limitée à une application à une chaussure de surf mais peut également être appliquée à d'autres chaussures de sport de glisse tel que patin, patin à roues en ligne,...etc.It is in particular not limited to an application to a surf shoe but can also be applied to other sliding sports shoes such as skates, inline skates, etc.
