An independent claim is also included for a sport shoe comprising a comfort element including a rubber and/or a flexible plastic material and/or tissue and/or foam.

Description

L'invention concerne un chausson intérieur de confort de chaussure de sport à tige rigide, et est particulièrement adaptée pour les chaussures utilisées dans les sports de glisse tel que le ski. Elle concerne aussi une chaussure de ski en tant que telle équipée d'un tel chausson.The invention relates to an inner shoe comfort shoe with rigid shaft, and is particularly suitable for shoes used in sports such as skiing. It also relates to a ski boot as such equipped with such a shoe.

Une chaussure de ski, surf des neiges, etc., se compose en général d'une tige rigide entourant un chausson dont une des fonctions est de garantir le confort du skieur malgré la pression élevée exercée par la tige rigide, qui remonte jusqu'à son tibia. Selon une solution courante de l'état de la technique, un tel chausson comprend une languette dans sa partie antérieure qui ferme par l'intérieur une échancrure, qui peut s'écarter sous la pression du pied à travers cette échancrure du chausson ainsi qu'au travers d'une échancrure de la tige rigide de la chaussure pour faciliter le chaussage et le déchaussage de la chaussure. Pour cela, la languette est montée mobile en rotation sur l'avant du chausson pour pouvoir occuper une position avancée écartée du chausson.A ski boot, snowboard, etc., generally consists of a rigid rod surrounding a liner, one of whose functions is to guarantee the skier's comfort despite the high pressure exerted by the rigid rod, which goes back to his shin. According to a current solution of the state of the art, such a shoe comprises a tongue in its front part which closes an indentation, which can deviate under the pressure of the foot through this notch of the shoe and through an indentation of the rigid upper of the shoe to facilitate the boot and the heaving of the shoe. For this, the tongue is rotatably mounted on the front of the liner to be able to occupy an advanced position away from the liner.

Malgré ce principe, le skieur a toujours un passage étroit et délicat à franchir lors du chaussage et du déchaussage d'une telle chaussure au niveau d'une zone allant du cou de pied au bas de jambe, où la partie avant de son pied doit effectuer une rotation de 90 degrés pour atteindre son logement horizontal final au sein de la coque depuis la partie verticale prévue pour le tibia, alors que son talon est en butée sur la paroi arrière de la chaussure. La figure 1 représente une coque 1 pied droit classique de chaussure de ski, qui est la partie inférieure de la tige rigide sur laquelle vient en général se monter un collier mobile en rotation pour couvrir le bas de jambe. Cette coque 1 comprend une partie basse 2 sensiblement horizontale formant un logement pour le pied, et une partie verticale 3 qui couvre d'une part le cou de pied 4, c'est-à-dire la zone de transition entre les parties horizontales et verticales de la coque, ce qui correspond à la cheville du skieur, et d'autre part le bas de jambe 5, et qui est destinée à être prolongée par un collier qui remonte jusqu'au tibia. Au niveau du bas de jambe 5 et du cou de pied 4, la coque 1 comprend une échancrure 6 dans sa partie antérieure, délimitée par deux arêtes respectivement médiale 7 et latérale 8. Ces arêtes s'étendent depuis une extrémité supérieure 9 dans la zone du bas de jambe 5 jusqu'à une extrémité 10 dans la zone du cou de pied 4, avant de laisser la place à deux rabats superposés 11, 12 recouvrant une échancrure horizontale dans la partie avant horizontale 2 de la coque 1. La difficulté principale lors du chaussage et du déchaussage d'une chaussure de sport comprenant une telle coque 1 consiste à franchir la zone du cou de pied 4. Pour faciliter ce passage, un skieur écarte au maximum la languette à travers d'une part l'échancrure du chausson de confort et d'autre part l'échancrure 6 de la coque. Dans ces conditions, il arrive que la surface supérieure du pied vienne directement en contact avec les tranches rigides 7, 8 de la coque 1 délimitant l'échancrure 6, ce qui est très douloureux. Ce phénomène se produit particulièrement au niveau de l'arête médiale 7 de la chaussure, correspondant à l'intérieur du pied.Despite this principle, the skier always has a narrow and delicate passage to pass when donning and removing such a shoe at an area from the instep to the lower leg, where the front part of his foot must rotate 90 degrees to reach its final horizontal housing within the hull from the vertical portion provided for the tibia, while its heel abuts on the rear wall of the shoe. The figure 1 represents a shell 1 classic ski boot right foot, which is the lower part of the rigid rod on which usually comes to mount a mobile collar in rotation to cover the lower leg. This shell 1 comprises a lower part 2 substantially horizontal forming a housing for the foot, and a vertical portion 3 which covers on the one hand the instep 4, that is to say the transition zone between the horizontal and vertical parts of the shell, which corresponds at the ankle of the skier, and secondly the lower leg 5, and which is intended to be extended by a collar that goes up to the shin. At the level of the lower leg 5 and the instep 4, the shell 1 comprises a notch 6 in its front part, delimited by two respectively medial 7 and lateral 8 edges 8. These edges extend from an upper end 9 in the zone from the lower leg 5 to one end 10 in the area of the instep 4, before giving way to two overlapping flaps 11, 12 covering a horizontal notch in the horizontal front portion 2 of the shell 1. The main difficulty when donning and releasing a sports shoe comprising such a shell 1 is to cross the area of the instep 4. To facilitate this passage, a skier spreads the tongue as far as possible through firstly the notch of the comfort slipper and on the other hand the notch 6 of the hull. Under these conditions, it happens that the upper surface of the foot comes directly in contact with the rigid slices 7, 8 of the shell 1 delimiting the notch 6, which is very painful. This phenomenon occurs particularly at the medial edge 7 of the shoe, corresponding to the inside of the foot.

D'autre part, la languette du chausson ainsi écartée se retrouve ensuite souvent mal positionnée par rapport au reste de la chaussure, a tendance notamment à se coincer latéralement sur la surface extérieure du chausson. En effet, pendant le chaussage, les bords semi-rigides de la languette croisent les bords souples de l'échancrure du chausson en général au niveau du cou de pied et en fin de chaussage, la languette a tendance à ne pas revenir facilement dans sa position de repos, au moins une partie de ses extrémités restant coincée sur la surface extérieure du chausson. Ce phénomène est particulièrement courant au niveau du cou de pied, où l'échancrure du chausson est très étroite et favorise le coincement de la languette. Or cette zone du cou de pied du chausson est recouverte par la tige rigide de la chaussure, est peu visible et peu accessible par l'utilisateur, qui, même s'il s'aperçoit de ce mauvais positionnement, éprouve de grandes difficultés pour remettre manuellement la languette en place. Finalement, ce phénomène a pour conséquences que cette solution courante de chausson de l'art antérieur se caractérise par des douleurs ressenties par l'utilisateur, en plus d'un mauvais maintien du pied.On the other hand, the tongue of the slipper and spread out is then often poorly positioned relative to the rest of the shoe, particularly tends to get stuck laterally on the outer surface of the boot. Indeed, during the boot, the semi-rigid edges of the tongue cross the soft edges of the notch of the boot generally at the level of the instep and at the end of footwear, the tongue tends not to return easily in its rest position, at least a portion of its ends remaining stuck on the outer surface of the slipper. This phenomenon is particularly common in the instep, where the notch of the liner is very narrow and promotes the jamming of the tongue. But this area of the instep of the bootie is covered by the rigid upper of the shoe, is not very visible and not easily accessible by the user, who, even if he realizes this bad positioning, has great difficulties to put back manually the tab in place. Finally, this phenomenon has the consequence that this current slipper solution of the prior art is characterized by pain felt by the user, in addition to poor foot maintenance.

Il existe donc un besoin d'une nouvelle structure de chaussure de sport rigide avec chausson intérieur qui permette d'éviter les inconvénients précédents des chaussures existantes.There is therefore a need for a new structure of rigid sports shoe with inner boot that avoids the previous disadvantages of existing shoes.

Un objet de la présente invention consiste donc à proposer un chausson de chaussure de sport assurant un bon maintien du pied et au chaussage facile, tout en offrant un confort amélioré.An object of the present invention is therefore to provide a shoe shoe slipper ensuring good support and easy footwear, while providing improved comfort.

Selon le concept de l'invention, la languette du chausson est reliée à au moins la paroi médiale du chausson par un élément de protection s'étendant dans sa plus grande partie au niveau d'une zone du chausson correspondant au bas de jambe pour empêcher les douleurs des solutions de l'état de la technique.According to the concept of the invention, the tongue of the liner is connected to at least the medial wall of the liner by a protective element extending in its greater part at a region of the liner corresponding to the lower leg to prevent the pains of the solutions of the state of the art.

L'invention est plus précisément définie par les revendications.The invention is more precisely defined by the claims.

Ces objets, caractéristiques et avantages de la présente invention seront exposés en détail dans la description suivante d'un mode d'exécution particulier fait à titre non-limitatif en relation avec les figures jointes parmi lesquelles.

  • La figure 1 illustre une vue en perspective de la face médiale d'une coque de chaussure de ski selon l'état de la technique ;
  • La figure 2 illustre une vue en perspective de dessus d'une chaussure de ski selon un mode d'exécution de l'invention ;
  • La figure 3 illustre une vue en perspective de face d'un chausson selon le mode d'exécution de l'invention ;
  • La figure 4 illustre une vue du côté médial d'un chausson selon le mode d'exécution de l'invention.
These objects, features and advantages of the present invention will be set forth in detail in the following description of an embodiment particular non-limiting in connection with the accompanying figures among which.
  • The figure 1 illustrates a perspective view of the medial side of a ski boot shell according to the state of the art;
  • The figure 2 illustrates a perspective view from above of a ski boot according to an embodiment of the invention;
  • The figure 3 illustrates a front perspective view of a shoe according to the embodiment of the invention;
  • The figure 4 illustrates a view of the medial side of a liner according to the embodiment of the invention.

L'invention va maintenant être illustrée dans le cadre d'une implémentation sur une chaussure de ski. Le concept de l'invention peut toutefois être implémenté sur toute autre chaussure de sport dont la structure se compose d'un chausson de confort intégré dans une tige rigide, comme une chaussure de surf des neiges par exemple.The invention will now be illustrated in the context of an implementation on a ski boot. The concept of the invention can, however, be implemented on any other sports shoe whose structure consists of a comfort slipper integrated in a rigid upper, such as a snowboard boot for example.

L'invention s'intéresse donc à l'amélioration du confort de ces chaussures de sport, particulièrement lors des phases de chaussage et déchaussage. Dans une telle phase, en considérant une chaussure pied droit telle qu'illustrée sur la figure 1, l'utilisateur saisit la languette 21 du chausson de la main droite et l'écarte vers l'extérieur, du côté latéral de la chaussure, laissant alors apparaître l'arête médiale rigide 7 de la coque, orientée vers l'intérieur, c'est-à-dire vers le pied gauche. Cette arête est la cause de douleurs comme cela a été détaillé plus haut car elle frotte sur le dessus du pied.The invention is therefore concerned with improving the comfort of these sports shoes, particularly during the boot and heave phases. In such a phase, considering a right foot shoe as illustrated on the figure 1 , the user grasps the tongue 21 of the slipper of the right hand and spreads it outwardly, on the lateral side of the shoe, leaving then the rigid medial edge 7 of the shell, facing inwards, c that is, to the left foot. This ridge is the cause of pain as it was detailed above because it rubs on the top of the foot.

Dans les différentes figures, les mêmes références sont utilisées pour désigner les mêmes éléments.In the different figures, the same references are used to designate the same elements.

La figure 2 représente un chausson et une chaussure de ski selon un mode d'exécution de l'invention. La chaussure de ski intègre un chausson de confort 20 dans une tige rigide. Cette dernière, par exemple dans un plastique rigide comme du polyuréthane de dureté entre 45 et 60 shD, se compose d'un collier 14 monté sur une coque 1 telle que celle décrite sur la figure 1. La coque comprend donc une partie horizontale 2 comprenant deux rabats 11, 12 sur lesquels sont montés des éléments de fermeture et serrage 13. Ces rabats 11, 12 sont reliés respectivement aux arêtes médiale 7 et latérale 8 de la partie sensiblement verticale de la coque 1, qui s'étendent depuis l'extrémité supérieure 9 dans le bas de jambe jusqu'à une extrémité inférieure 10, au niveau du cou de pied, et qui délimitent l'échancrure avant de la coque. Le collier 14 est de même dans un matériau rigide et recouvre le chausson 20 et la coque 1 dans une zone sensiblement verticale s'étendant approximativement du bas de jambe jusqu'au tibia. Il comprend aussi une échancrure antérieure autour de laquelle sont montés des éléments de serrage et fermeture 15. Pour des raisons de clarté de représentation de l'invention, le collier 14 est simplifié et tronqué.The figure 2 represents a liner and a ski boot according to an embodiment of the invention. The ski boot incorporates a comfort boot 20 into a rigid upper. The latter, for example in a rigid plastic such as polyurethane hardness between 45 and 60 shD, consists of a collar 14 mounted on a shell 1 such as that described on the figure 1 . The shell therefore comprises a horizontal portion 2 comprising two flaps 11, 12 on which are mounted closing and clamping elements 13. These flaps 11, 12 are respectively connected to the medial edge 7 and side 8 of the substantially vertical portion of the shell 1 , which extend from the upper end 9 in the lower leg to a lower end 10, at the instep, and which delimit the notch front of the hull. The collar 14 is likewise in a rigid material and covers the liner 20 and the shell 1 in a substantially vertical zone extending approximately from the lower leg to the tibia. It also comprises an anterior notch around which clamping and closure elements 15 are mounted. For reasons of clarity of representation of the invention, the collar 14 is simplified and truncated.

Le chausson 20 comprend une languette 21 dans sa partie antérieure, fermant une échancrure 22 du chausson 20, fixée dans la zone antérieure de la chaussure de sorte de permettre une mobilité en rotation de la languette 21 autour d'un axe virtuel sensiblement transverse 23, positionné à proximité de la frontière antérieure 16 des rabats 11, 12 de la coque de la chaussure. Sur la figure, la languette 21 est représentée dans une position écartée comme elle peut l'être lors d'une phase de chaussage ou déchaussage de la chaussure. Dans cette configuration, il apparaît que la languette 21 ressort au-delà de l'échancrure 22 du chausson 20 et force sur la coque 1 de sorte d'écarter les arêtes 7, 8 délimitant l'échancrure 6 afin d'agrandir cette échancrure et d'augmenter l'espace intérieur de la chaussure pour le passage du pied. Dans cette configuration, la languette 21 et la paroi latérale médiale 24 du chausson ne suffisent plus pour bien protéger le pied de l'arête médiale 7 de la coque 1. Selon un élément essentiel de l'invention, le chausson 20 comprend un élément de protection 25 relié d'une part sur le bord médial de la languette 21 et d'autre part sur le bord médial 24 du chausson, s'étendant verticalement sur une zone correspondant sensiblement à l'arête médiale 7 de la coque 1 de la chaussure.The liner 20 comprises a tongue 21 in its front part, closing an indentation 22 of the liner 20, fixed in the anterior zone of the boot so as to allow a rotational mobility of the tongue 21 around a substantially transverse virtual axis 23, positioned near the anterior border 16 of the flaps 11, 12 of the hull of the shoe. In the figure, the tongue 21 is shown in a spaced apart position as it may be during a booting phase or loosening of the boot. In this configuration, it appears that the tongue 21 leaves beyond the notch 22 of the shoe 20 and forces on the shell 1 so as to spread the edges 7, 8 delimiting the notch 6 to enlarge this notch and increase the interior space of the shoe for the passage of the foot. In this configuration, the tongue 21 and the medial side wall 24 of the liner are no longer sufficient to properly protect the foot of the medial edge 7 of the shell 1. According to an essential element of the invention, the liner 20 comprises an element of 25 connected on the one hand on the medial edge of the tongue 21 and secondly on the medial edge 24 of the liner, extending vertically on an area substantially corresponding to the medial edge 7 of the shell 1 of the shoe .

Les figures 3 et 4 représentent un chausson 20 isolé implémentant la solution selon le mode d'implémentation de l'invention. Un tel chausson 20 peut être départagé en quatre zones, une zone avant 26, une zone de cou de pied 27, une zone de bas de jambe 28 et une zone de tibia 29. Comme cela est visible, la languette 21 est mobile en rotation autour d'un axe 23 positionné dans la zone avant 26 du chausson, comprend un élément de protection 25 dont la partie inférieure 30 se trouve dans la zone du cou de pied 27 ou juste au-dessus, et qui s'étend principalement dans la zone du bas de jambe 28, sa partie supérieure 31 s'arrêtant à proximité de la zone de tibia 29.The figures 3 and 4 represent an isolated slipper implementing the solution according to the embodiment of the invention. Such a liner 20 can be divided into four zones, a front zone 26, an instep zone 27, a lower leg zone 28 and a tibia zone 29. As can be seen, the tongue 21 is rotatable. around an axis 23 positioned in the front zone 26 of the liner, comprises a protection element 25 whose lower part 30 is in the area of the instep 27 or just above, and which extends mainly in the lower leg zone 28, its upper portion 31 stopping near the tibia zone 29.

Pour remplir sa fonction de protection, l'élément de protection 25 est dans un matériau souple, pour ne pas perturber le mouvement de la languette 21. Il peut être par exemple en caoutchouc ou en plastique souple ou en tissu. Il peut comprendre un matériau de confort, comme une mousse de confort. En remarque, l'élément de protection décrit ne doit pas être confondu avec un élément d'étanchéité. En effet, il ne représente pas une solution d'étanchéité comme un soufflet, puisqu'il n'occupe pas toute la surface entre la languette et le reste du chausson mais laisse des espaces libres, notamment vers l'avant du chausson.To fulfill its protective function, the protective element 25 is in a flexible material, so as not to disturb the movement of the tongue 21. It may be for example rubber or flexible plastic or fabric. It can include a comfort material, such as a comfort foam. As a remark, the protection element described must not be confused with a sealing element. Indeed, it does not represent a sealing solution as a bellows, since it does not occupy the entire surface between the tongue and the rest of the boot but leaves free spaces, especially towards the front of the boot.

L'élément de protection 25 peut remplir sa fonction de protection de deux manières différentes, selon deux modes d'exécution de l'invention.The protection element 25 can fulfill its protection function in two different ways, according to two embodiments of the invention.

Selon un premier mode d'exécution de l'invention, il s'intercale directement entre la tige rigide et le pied d'un utilisateur et remplit sa fonction de protection en apportant une couche intermédiaire entre la tige rigide et le pied d'un utilisateur. Il vient en effet se positionner entre le pied du skieur et l'arête rigide médiale 7 de la coque de sorte de réduire fortement les risques de douleur ressentie par le skieur dans une configuration de chaussage et déchaussage de la chaussure. Dans un tel mode d'exécution, il pourra comprendre une couche de confort, par exemple en mousse ou en tissu, associée à un tissu en PVC. De plus, il comprendra une hauteur suffisante pour couvrir la totalité de l'arête rigide 7, et sa partie supérieure 31 viendra au moins au niveau de la partie supérieure 9 de l'arête rigide.According to a first embodiment of the invention, it is inserted directly between the rigid rod and the foot of a user and fulfills its protective function by providing an intermediate layer between the rigid rod and the foot of a user . It is indeed positioned between the skier's foot and the rigid medial ridge 7 of the shell so as to greatly reduce the risk of pain felt by the skier in a boot configuration and release of the shoe. In such an embodiment, it may include a comfort layer, for example foam or fabric, associated with a PVC fabric. In addition, it will include a height sufficient to cover the entire rigid edge 7, and its upper portion 31 will at least at the upper portion 9 of the rigid edge.

Selon un second mode d'exécution de l'invention, il remplit sa fonction de protection de manière indirecte, en limitant l'amplitude de mouvement vers l'avant de la languette 21, de sorte que la languette 21 reste toujours intercalée entre le pied et la tige rigide, particulièrement entre l'arête rigide 7 de la coque et le pied à l'intérieur du chausson, même quand l'élément de protection est tendu au maximum vers l'avant, la languette atteignant sa position de butée la plus en avant. En remarque, cette solution limite de plus le second problème de coincement de la languette rappelé en préambule. Pour cela, on choisira un élément de protection dont les dimensions peuvent être de l'ordre de 40 millimètres de longueur, mesurée entre le bord médial du chausson autour de l'échancrure et le bord médial de la languette. Une longueur entre 30 et 50 millimètres pourra convenir. Sa hauteur pourra être moins étendue que dans le mode d'exécution précédent et être inférieure à l'arête rigide 7 de la coque. La partie la plus importante de sa hauteur se trouvera dans la zone du bas de jambe 28.According to a second embodiment of the invention, it fulfills its protective function indirectly, by limiting the amplitude of movement towards the front of the tongue 21, so that the tongue 21 always remains interposed between the foot and the rigid rod, particularly between the rigid edge 7 of the shell and the foot inside the liner, even when the protection element is stretched as far forward as possible, the tongue reaching its most effective stop position forward. As a note, this solution also limits the second jamming problem of the tongue recalled in the preamble. For this, we choose a protective element whose dimensions can be of the order of 40 millimeters in length, measured between the medial edge of the liner around the notch and the medial edge of the tongue. A length between 30 and 50 millimeters may be suitable. Its height may be less extensive than in the mode previous execution and be lower than the rigid edge 7 of the shell. The most important part of its height will be in the zone of the bottom of leg 28.

En remarque, même dans le premier mode d'exécution, l'élément de protection 25 représente aussi une limitation de l'amplitude de mouvement de la languette, susceptible de réduire les coincements de la languette et de réduire les situations d'apparition de la tige rigide directement en contact avec le pied de l'utilisateur. Il peut ainsi cumuler plus ou moins les deux fonctions de protection directe et indirecte.As a remark, even in the first embodiment, the protection element 25 also represents a limitation of the range of movement of the tongue, which can reduce the jamming of the tongue and reduce the situations of appearance of the tongue. rigid rod directly in contact with the foot of the user. It can accumulate more or less both direct and indirect protection functions.

Selon une variante d'exécution, il est possible d'utiliser un matériau élastique pour l'élément de protection, qui va se déformer sous l'effet d'une traction vers l'avant de la languette en opposant une force de plus en plus forte de manière progressive, jusqu'à représenter une butée du mouvement d'écartement de la languette. Ensuite, il permet de procurer un effort de rappel vers la position initiale de la languette.According to an alternative embodiment, it is possible to use an elastic material for the protection element, which will deform under the effect of pulling forward of the tongue by opposing a force more and more. strong in a progressive way, to represent an abutment of the movement of separation of the tongue. Then, it provides a return force to the initial position of the tongue.

L'invention a été illustrée avec un élément de protection de forme la plus simple, sensiblement rectangulaire. Toutefois, d'autres formes sont possibles sans sortir du concept de l'invention. De plus, cet élément peut être fixé par tout moyen mécanique de type couture, ou par un collage, une soudure...The invention has been illustrated with a simplest, substantially rectangular shape-protecting element. However, other forms are possible without departing from the concept of the invention. In addition, this element can be fixed by any mechanical means of the seam type, or by gluing, welding ...

De plus, l'invention a été illustrée dans le cas d'une chaussure dont la tige rigide se compose de l'association d'une coque et d'un collier mais le concept décrit peut naturellement s'appliquer avec d'autres structures de tiges rigides de chaussure de sport.In addition, the invention has been illustrated in the case of a shoe whose rigid shaft is composed of the combination of a shell and a collar, but the concept described can naturally be applied with other structures of rigid sports shoe stems.

L'invention a été illustrée avec un seul élément de protection sur le côté médial du chausson. Toutefois, un élément similaire pourrait aussi être positionné sur l'autre côté dit latéral du chausson, correspondant à la partie extérieure du pied.The invention has been illustrated with a single protective element on the medial side of the liner. However, a similar element could also be positioned on the other side said side of the boot, corresponding to the outer part of the foot.

Finalement, la solution atteint bien les objets recherchés et présente les avantages suivants :

  • le chaussage/déchaussage du chausson reste aussi convivial qu'auparavant, la languette étant toujours dotée de son mouvement de rotation vers l'avant pour s'écarter sous l'effet de la pression d'un pied lors du chaussage et du déchaussage ;
  • le pied n'est plus directement heurté par les parties rigides de la tige rigide de la chaussure lors du chaussage/déchaussage et l'utilisateur en ressent un confort accru ;
  • le maintien du pied est garanti. La languette, qui reste en position de repos dans l'échancrure du chausson, assure un bon maintien notamment sur le pourtour du bas de jambe de l'utilisateur. Cette solution procure une sensation de bon enveloppement du pied et permet d'atteindre une meilleure efficacité de la chaussure ;
  • enfin, la solution retenue améliore le confort de l'utilisateur en améliorant le bon positionnement de la languette.
Finally, the solution achieves the desired objects and has the following advantages:
  • the boot / heave of the boot remains as friendly as before, the tongue is always provided with its forward rotation to move away under the effect of the pressure of a foot during the boot and heaving;
  • the foot is no longer directly hit by the rigid parts of the rigid upper of the boot when donning / heaving and the user feels increased comfort;
  • foot support is guaranteed. The tongue, which remains in the rest position in the notch of the liner, provides a good hold especially on the perimeter of the lower leg of the user. This solution provides a feeling of good wrapping of the foot and allows to achieve a better effectiveness of the shoe;
  • finally, the chosen solution improves the comfort of the user by improving the proper positioning of the tongue.
