Description

Structure pour chaussure, réalisée en matériau synthétique souple et destinée à être disposée entre une semelle extérieure et la tige de la chaussure Shoe structure, made of flexible synthetic material and intended to be disposed between an outsole and the upper of the shoe
L'invention concerne une structure pour chaussure ainsi qu'une chaussure correspondante.The invention relates to a shoe structure and a corresponding shoe.
Elle concerne plus particulièrement le domaine des chaussures de sport.It relates more particularly to the field of sports shoes.
Afin d'adapter la chaussure aux mouvements naturels du pied lors de la course et de protéger au mieux le coureur des traumatismes, la chaussure doit posséder certaines qualités qui seront détaillées ci-après.In order to adapt the shoe to the natural movements of the foot during the race and to better protect the runner from trauma, the shoe must have certain qualities which will be detailed below.
Nous rappellerons tout d'abord le mécanisme de la foulée. Cette dernière peut varier suivant les coureurs et est généralement classée en trois catégories distinctes, à savoir la foulée pronatrice, universelle ou supinatrice.We will first recall the mechanism of the stride. The latter may vary according to the riders and is generally classified into three distinct categories, namely the pronation stride, universal or supine.
La foulée universelle est la plus répandue, celle-ci concernant environ 50% des coureurs.The universal stride is the most widespread, it concerns about 50% of runners.
Un coureur à foulée universelle commence le mouvement de déroulé par l'extérieur du talon.A universal strider starts the movement of unwound by the outside of the heel.
Avant d'arriver au sol, le pied est incliné vers l'extérieur. Quand le contact intervient, la pointe de pied est encore dirigée vers l'extérieur, les orteils étant relevés. Rapidement, l'appui progresse vers l'avant et l'intérieur du pied. A ce moment, la tension de la voûte plantaire augmente.Before reaching the ground, the foot is inclined outwards. When the contact occurs, the toe is still directed outwards, the toes being raised. Quickly, the support progresses towards the front and inside of the foot. At this moment, the tension of the arch increases.
Alors que l'appui arrive sur l'avant du pied, le mouvement de déroulé de l'extérieur vers l'intérieur continue de progresser. La propulsion est réalisée principalement par le gros orteil. Au dernier moment, le pied peut légèrement se rouvrir sur l'extérieur.As the support arrives on the front of the foot, the movement of unwinding from the outside to the inside continues to progress. The propulsion is performed mainly by the big toe. At the last moment, the foot can slightly reopen on the outside.
Au total, le déroulé de pied au sol, pendant une course lente, aura duré VA de seconde, ce temps diminuant avec la vitesse.In total, the roll of foot on the ground, during a slow race, will have lasted VA of second, this time decreasing with the speed.
On comprend dès lors que le déroulé du pied est un mouvement composé complexe, associant flexion, torsion et rotation du pied, ceci quel que soit le type de foulée du coureur.It is understandable therefore that the unwinding of the foot is a complex compound movement, combining flexion, torsion and rotation of the foot, this regardless of the type of stride of the runner.
La chaussure doit donc être capable de respecter le mouvement anatomique du pied lors de la course.The shoe must therefore be able to respect the anatomical movement of the foot during the race.
En outre, la chaussure doit posséder des qualités additionnelles énumérées ci-après. Tout d'abord la chaussure doit être confortable. Celle-ci doit également posséder de bonnes propriétés d'amortissement, permettant de protéger des chocs engendrés par chaque impact du pied sur le sol. En outre, la chaussure doit permettre le maintien du pied, pour garantir la tenue de celui- ci et contrôler la foulée pronatrice ou supinatrice. De plus, celle-ci doit assurer la stabilité, généralement au niveau de la zone médiane longitudinale du pied. Cette propriété est particulièrement importante en cas de course ou de randonnée en terrain accidenté. Enfin, la chaussure doit posséder des propriétés dynamiques accrues, à savoir une bonne restitution de l'énergie absorbée de manière à relancer la foulée.In addition, the shoe must have additional qualities listed below. First of all the shoe must be comfortable. It must also have good damping properties, allowing protect from shocks caused by each impact of the foot on the ground. In addition, the shoe must allow the maintenance of the foot, to ensure the holding thereof and to control the pronation or supine stride. In addition, it must provide stability, generally at the longitudinal center zone of the foot. This property is particularly important in case of race or hike in rough terrain. Finally, the shoe must have increased dynamic properties, namely a good return of energy absorbed so as to restart the stride.
Certaines chaussures visent à améliorer ces propriétés. Elles intègrent pour cela plusieurs dispositifs distincts, chaque dispositif étant dédié à une ou deux propriétés seulement des propriétés recherchées de la chaussure.Some shoes aim to improve these properties. They integrate for this purpose several distinct devices, each device being dedicated to one or two properties only of the desired properties of the shoe.
C'est ainsi qu'un dispositif d'amortissement disposé au niveau du talon est décrit dans le document US 2006/112592 et qu'une structure favorisant l'amortissement et la stabilité, prévue au niveau du talon et de la zone médiane de la chaussure, est décrite dans le document US 6 647 645.Thus, a damping device arranged at the level of the heel is described in document US 2006/112592 and that a structure promoting damping and stability, provided at the level of the heel and the middle zone of the shoe, is described in US 6,647,645.
En outre, l'efficacité des dispositifs existants est contestable et l'intégration de dispositifs distincts s'oppose au suivi du déroulé continu du pied.In addition, the effectiveness of existing devices is questionable and the integration of separate devices opposes the monitoring of the continuous roll of the foot.
Le but de la présente invention est de remédier à ces inconvénients, en proposant une structure pour chaussure peu complexe permettant d'améliorer efficacement l'ensemble des propriétés de cette dernière, à savoir notamment l'amortissement, le maintien, la stabilité et le dynamisme, tout en respectant le déroulé anatomique du pied.The object of the present invention is to overcome these disadvantages, by proposing a shoe structure with little complex to effectively improve all the properties of the latter, namely including damping, maintenance, stability and dynamism , while respecting the anatomical roll of the foot.
A cet effet, l'invention concerne une structure pour chaussure, réalisée en matériau synthétique souple et destinée à être disposée entre une semelle extérieure et la tige de la chaussure, caractérisée en ce qu'elle comporte au moins deux éléments longitudinaux sensiblement parallèles disposés à proximité des bords de la structure, reliés par au moins deux traverses s'étendant sensiblement perpendiculairement aux éléments longitudinaux, les traverses présentant au moins en partie une section tubulaire d'axe longitudinal et de forme générale ovale, délimitant une zone creuse.To this end, the invention relates to a shoe structure, made of flexible synthetic material and intended to be disposed between an outer sole and the upper of the shoe, characterized in that it comprises at least two substantially parallel longitudinal elements arranged at close to the edges of the structure, connected by at least two cross members extending substantially perpendicular to the longitudinal elements, the cross members having at least partly a tubular section of longitudinal axis and generally oval, defining a hollow zone.
Les éléments longitudinaux, tout en permettant la flexion de la structure pour suivre la flexion du pied, favorise le maintien et la stabilité.The longitudinal elements, while allowing the bending of the structure to follow the flexion of the foot, promotes the maintenance and stability.
La forme tubulaire des traverses permet de réaliser un amortissement du pied. De plus, les traverses, grâce à leur forme ovale et à la souplesse des éléments longitudinaux qui lient l'ensemble, permettent par leur élasticité de restituer l'énergie de l'impact pour la transformer en énergie dynamique.The tubular form of the sleepers makes it possible to achieve a damping of the foot. In addition, the sleepers, thanks to their oval shape and the flexibility of the longitudinal elements that bind the whole, allow by their elasticity to restore the energy of the impact to transform it into dynamic energy.
On obtient ainsi une structure unique apportant l'ensemble des propriétés recherchées.This gives a unique structure providing all the desired properties.
Selon une possibilité de l'invention, au moins une des traverses est réalisée en polyuréthanne thermoplastique.According to a possibility of the invention, at least one of the crosspieces is made of thermoplastic polyurethane.
Avantageusement, au moins un des éléments longitudinaux est réalisé en polyuréthanne thermoplastique basse densité. Préférentiellement, au moins une des traverses présente des parois inférieure et supérieure sensiblement parallèles, des orifices étant ménagés dans la paroi supérieure et/ou dans la paroi inférieure.Advantageously, at least one of the longitudinal elements is made of low density thermoplastic polyurethane. Preferably, at least one of the crosspieces has substantially parallel lower and upper walls, orifices being formed in the upper wall and / or in the lower wall.
Les orifices permettent de favoriser la déformation des traverses tubulaires de manière à encaisser les chocs lors de l'impact de la chaussure. Avantageusement, au moins une des traverses comporte des plots réalisés en matière synthétique et disposés dans sa zone creuse.The orifices are used to promote the deformation of the tubular sleepers so as to withstand shocks during the impact of the shoe. Advantageously, at least one of the sleepers comprises studs made of synthetic material and arranged in its hollow zone.
Suivant leur nature, les plots peuvent avoir des propriétés d'amortissement ou de restitution d'énergie.Depending on their nature, the pads may have damping properties or energy restoration.
Selon une possibilité de l'invention, les plots s'étendent depuis la paroi inférieure de la traverse, en direction de la paroi supérieure.According to a possibility of the invention, the studs extend from the bottom wall of the cross member, in the direction of the upper wall.
Selon une forme de réalisation particulière, les plots viennent de moulage avec une plaque fixée à la paroi supérieure ou à la paroi inférieure de la traverse correspondante.According to a particular embodiment, the pads are molded with a plate attached to the upper wall or the bottom wall of the corresponding crossbar.
Selon une caractéristique de l'invention, la zone creuse d'au moins une traverse est remplie, au moins partiellement, par un élément d'absorption de chocs en matériau souple, préférentiellement en mousse de polyuréthanne ou en silicone.According to one characteristic of the invention, the hollow zone of at least one cross member is filled, at least partially, by a shock absorbing element of flexible material, preferably of polyurethane foam or silicone.
Une traverse peut être équipée à la fois d'un élément d'absorption de chocs et de plots, l'élément d'absorption de chocs comportant alors des évidements pour l'engagement des plots.A cross member can be equipped with both a shock absorbing element and pads, the shock absorbing element then having recesses for the engagement of the pads.
Préférentiellement, au moins une des traverses est équipée de pattes latérales de positionnement et de maintien, s'étendant vers le haut et/ou vers le bas au niveau de la paroi supérieure et /ou de la paroi inférieure des traverses, destinées à coopérer avec les zones latérales de la tige et/ou de la semelle intermédiaire de la chaussure. Préférentiellement, la structure comporte une traverse médiane qui, située au niveau de la zone médiane de la structure suivant l'axe longitudinal, présente un tronçon central plein de part et d'autre duquel s'étendent deux tronçons tubulaires débouchant vers l'extérieur, respectivement vers l'avant et l'arrière.Preferably, at least one of the crosspieces is equipped with lateral positioning and holding tabs, extending upwardly and / or downwardly at the level of the upper wall and / or the bottom wall of the crosspieces, intended to cooperate with the lateral zones of the upper and / or the midsole of the boot. Preferably, the structure comprises a median crossbar which, located at the level of the median zone of the structure along the longitudinal axis, has a solid central section on either side of which extend two tubular sections opening towards the outside, respectively forward and backward.
La traverse médiane permet d'apporter une rigidité suffisante à la structure dans la zone correspondant au milieu du pied.The median crossbar provides sufficient rigidity to the structure in the area corresponding to the middle of the foot.
Avantageusement, les éléments longitudinaux sont disposés latéralement vis-à-vis des traverses, à une distance comprise entre 5 et 20 mm du bord latéral correspondant de celles-ci.Advantageously, the longitudinal elements are arranged laterally with respect to the crosspieces, at a distance of between 5 and 20 mm from the corresponding lateral edge thereof.
La distance entre les éléments et le bord correspondant peut être modifiée de manière à ajuster la capacité de déformation de la structure à la torsion.The distance between the elements and the corresponding edge can be modified so as to adjust the deformation capacity of the structure to torsion.
Préférentiellement, les traverses sont espacées longitudinalement les unes par rapport aux autres d'une distance supérieure ou égale à 8 mm.Preferably, the cross members are spaced longitudinally relative to each other by a distance greater than or equal to 8 mm.
Cette distance minimale permet d'assurer une articulation ou flexion suffisante de la structure.This minimum distance ensures a sufficient articulation or flexion of the structure.
Selon une caractéristique de l'invention, chaque élément longitudinal est réalisé par une pluralité de languettes s'étendant longitudinalement et reliant au moins deux traverses.According to one characteristic of the invention, each longitudinal element is formed by a plurality of tongues extending longitudinally and connecting at least two crosspieces.
Selon une variante, les éléments longitudinaux viennent chacun de moulage en une seule pièce.According to one variant, the longitudinal elements each come in one-piece molding.
Préférentiellement, les éléments longitudinaux sont assemblés par surmoulage sur les traverses au niveau de leur paroi supérieure et/ou de leur paroi inférieure.Preferably, the longitudinal elements are assembled by overmoulding on the crosspieces at their upper wall and / or their bottom wall.
Avantageusement, au moins une des traverses comporte des évidements au niveau de sa paroi supérieure et/ou inférieure, s'étendant sensiblement selon l'axe de la structure et dont la hauteur est sensiblement égale à l'épaisseur des éléments longitudinaux dans leur zone de fixation à la traverse.Advantageously, at least one of the crosspieces has recesses at its upper and / or lower wall, extending substantially along the axis of the structure and whose height is substantially equal to the thickness of the longitudinal elements in their zone of fastening to the crossbar.
De cette manière, les éléments longitudinaux sont noyés dans les évidements lors de l'assemblage sur les traverses.In this way, the longitudinal elements are embedded in the recesses during assembly on the sleepers.
Selon une caractéristique de l'invention, la structure comporte un troisième élément longitudinal relié à la traverse avant et à la traverse contiguë située en arrière, disposé entre les éléments longitudinaux latéraux, sensiblement suivant l'axe longitudinal médian de la structure. Le troisième élément longitudinal confère une rigidité accrue de la structure à l'avant du pied.According to one characteristic of the invention, the structure comprises a third longitudinal element connected to the front cross member and to the adjacent rear cross member disposed between the longitudinal longitudinal elements, substantially along the median longitudinal axis of the structure. The third longitudinal element imparts increased rigidity of the structure to the forefoot.
Selon une possibilité de l'invention, l'épaisseur de la structure est inférieure à 2 mm en partie avant et inférieure à 30 mm en partie arrière. Selon une forme de réalisation, la structure comporte au moins cinq traverses.According to a possibility of the invention, the thickness of the structure is less than 2 mm at the front and less than 30 mm at the rear. According to one embodiment, the structure comprises at least five sleepers.

La figure 1 représente une chaussure 1 selon l'invention, comportant, de haut en bas, une tige 2, une semelle interne dite également semelle de propreté (non représentée), une structure intermédiaire 3, une semelle intermédiaire 4 en éthylène-acétate de vinyle (E.V.A.) et une semelle externe 5 en caoutchouc.FIG. 1 represents a shoe 1 according to the invention, comprising, from top to bottom, a shank 2, an insole also known as sockliner (not shown), an intermediate structure 3, a midsole 4 made of ethylene-acetate, vinyl (EVA) and a rubber outsole 5.
L'invention porte plus particulièrement sur la structure intermédiaire.The invention relates more particularly to the intermediate structure.
Comme représenté en figure 2 à 5, la structure comporte deux paires d'éléments longitudinaux 6, 8 ; 7, 9 sensiblement parallèles, réalisés en polyuréthanne thermoplastique basse densité et disposés à proximité des bords de la structure 3. II est à noter que d'autres matériaux souples pourraient être utilisés, par exemple le silicone ou un élastomère.As represented in FIGS. 2 to 5, the structure comprises two pairs of longitudinal elements 6, 8; 7, 9 substantially parallel, made of low density thermoplastic polyurethane and arranged near the edges of the structure 3. It should be noted that other flexible materials could be used, for example silicone or an elastomer.
Ceux-ci sont reliés par des traverses 10 à 15 s'étendant sensiblement perpendiculairement aux éléments longitudinaux 6 à 9. La structure comporte 6 traverses 10 à 15, référencées ci-après de l'avant vers l'arrière du pied et réalisée en polyuréthanne thermoplastique (TPU).These are connected by crosspieces 10 to 15 extending substantially perpendicularly to the longitudinal elements 6 to 9. The structure comprises 6 crosspieces 10 to 15, referenced hereinafter from the front to the back of the foot and made of polyurethane thermoplastic (TPU).
Les parties avants 6, 7 des éléments longitudinaux relient les traverses 10 à 13, de la première 10 située à l'avant du pied, à la quatrième 13 située au niveau de la zone centrale du pied.The front portions 6, 7 of the longitudinal elements connect the cross members 10 to 13, the first 10 located at the front of the foot, the fourth 13 located at the central zone of the foot.
Les parties arrières 8, 9 des éléments longitudinaux relient les traverses 13 à 15, de la quatrième 13 à la sixième traverse 15 située à l'arrière du pied.The rear portions 8, 9 of the longitudinal elements connect the cross members 13 to 15, the fourth 13 to the sixth cross 15 at the rear of the foot.
Un élément longitudinal additionnel 16, reliant la première traverse 10 à la seconde 11 , est disposé entre les éléments longitudinaux latéraux 6, 7, sensiblement suivant l'axe longitudinal médian de la structure 3.An additional longitudinal element 16, connecting the first cross member 10 to the second 11, is disposed between the lateral longitudinal elements 6, 7, substantially along the median longitudinal axis of the structure 3.
Les éléments longitudinaux 6 à 9 comportent, entre deux traverses, une zone élastique 17 en forme d'arc de cercle, visible plus particulièrement en figure 9 et permettant une meilleure flexion ou articulation de la structure. Ces éléments 6 à 9 comportent en outre des zones de plus faible largeur 18, situées dans les zones d'assemblage respectives avec les traverses 11 , 12, 14.The longitudinal elements 6 to 9 comprise, between two crosspieces, an elastic zone 17 in the shape of an arc of a circle, visible more particularly in FIG. 9 and allowing a better bending or articulation of the structure. These elements 6 to 9 further comprise zones of smaller width 18, located in the respective assembly areas with the crosspieces 11, 12, 14.
Les traverses, hormis la traverse 13 située dans la zone médiane du pied dans le sens longitudinal, présentent une section tubulaire, de forme générale ovale, et délimitant une zone creuse s'étendant longitudinalement.The sleepers, except the cross member 13 located in the middle zone of the foot in the longitudinal direction, have a tubular section, generally oval in shape, and delimiting a hollow zone extending longitudinally.
La traverse 13 située dans la zone médiane du pied comporte un tronçon central plein 19, de part et d'autre duquel s'étendent deux tronçons tubulaires 20, 21 débouchant vers l'extérieur, respectivement vers l'avant et l'arrière. Selon une possibilité de l'invention non représentée ici, la traverse médiane 13 ne comporte pas de tronçon tubulaire et est entièrement pleine.The cross member 13 located in the middle zone of the foot has a solid central portion 19, on either side of which extend two tubular sections 20, 21 opening outwards, respectively forward and rearward. According to a possibility of the invention not shown here, the median crosspiece 13 does not have a tubular section and is completely full.
La traverse médiane 13 est obtenue à partir d'un élément tubulaire dont les parois inférieure et supérieure sont soudées entre elles par l'intermédiaire de lignes de soudures 22. Les première 10 et sixième 15 traverses sont fermées au niveau de leur extrémité respectivement avant et arrière. Les traverses présentent des parois inférieure .23 et supérieure 24 planes ou légèrement bombées, présentant des ouvertures 25 débouchant au niveau de la zone creuse.The median crosspiece 13 is obtained from a tubular element whose lower and upper walls are welded together by means of weld lines 22. The first 10 and sixth crosspieces are closed at their end respectively before and back. The crosspieces have flat and slightly domed lower and upper walls 24, having apertures 25 opening at the hollow zone.
Les ouvertures 25 sont de forme diverse et fonction de l'application recherchée et de la position de la traverse. Elles sont par exemple rondes, ovale, carrée ou en forme générale de croix ou d'hélice.The openings 25 are of various shape and function of the desired application and the position of the cross. They are for example round, oval, square or generally cross or propeller.
Les traverses comportent des plots non représentés aux figures 2 à 5 et s'étendant à l'intérieur de la zone creuse, depuis la paroi inférieure 23 de la traverse en direction de la paroi supérieure 24. Les traverses comportent en outre des pattes latérales 26 de positionnement et de maintien venant de moulage avec la traverse. Ces pattes 26 s'étendent vers le haut à partir de la paroi supérieure 24 des traverses et sont destinées à coopérer avec les zones latérales de la tige 2 de la chaussure. De mêmes, les traverses sont équipées de pattes similaires 27 s'étendant vers le bas à partir de la paroi inférieure 23, destinées à coopérer avec les zones latérales de la semelle intermédiaire 4.The sleepers comprise studs not shown in FIGS. 2 to 5 and extending inside the hollow zone, from the bottom wall 23 of the cross member towards the upper wall 24. The crosspieces furthermore comprise lateral tabs 26 positioning and retaining molded with the cross. These lugs 26 extend upwardly from the upper wall 24 of the sleepers and are intended to cooperate with the lateral zones of the upper 2 of the boot. Similarly, the sleepers are equipped with similar tabs 27 extending downwards from the bottom wall 23, intended to cooperate with the lateral zones of the midsole 4.
Selon une variante de réalisation représentée en figures 6 à 8, les zones creuses des traverses sont remplies par un élément d'absorption de chocs 28 en matériau souple, préférentiellement réalisé en mousse de polyuréthanne ou en silicone.According to an alternative embodiment shown in FIGS. 6 to 8, the hollow zones of the crosspieces are filled by a shock absorbing element 28 made of flexible material, preferably made of polyurethane foam or silicone.
Dans cette forme de réalisation, comme cela apparaît plus particulièrement en figure 8, les plots 29 viennent de moulage avec une plaque support 30 fixée à la paroi inférieure 23 de la traverse correspondante 11 , 12, 14, à l'intérieure de la zone creuse. L'élément d'absorption de chocs 28 présente alors des évidements 31 permettant de loger les plots 29.In this embodiment, as appears more particularly in FIG. 8, the studs 29 are molded with a support plate 30 fastened to the bottom wall 23 of the corresponding cross member 11, 12, 14, inside the hollow zone. . The shock absorbing element 28 then has recesses 31 for housing the studs 29.
Indépendamment de la variante de réalisation, les parois supérieures 24 des traverses sont équipées d'évidements 32 de largeur et de hauteur égale à celle des éléments longitudinaux 6 à 9, comme visible en figure 8.Independently of the variant embodiment, the upper walls 24 of the crosspieces are equipped with recesses 32 of width and height equal to that of the longitudinal elements 6 to 9, as can be seen in FIG. 8.
Comme cela apparaît en figure 9, les éléments longitudinaux 6 à 9 sont disposés dans les évidements 32 et sont assemblées aux traverses par thermo soudage, plus particulièrement par surmoulage ou surinjection.As it appears in FIG. 9, the longitudinal elements 6 to 9 are arranged in the recesses 32 and are assembled to the crosspieces by thermo-welding, more particularly by overmolding or over-injection.
La position des éléments longitudinaux 6 à 9 sur les traverses ainsi que la position des traverses entre elles est réalisée de telle manière que deux traverses contiguës soit espacées d'au minium 8 mm et que les éléments longitudinaux 6 à 9 soient disposées à une distance comprise entre 5 et 20 mm du bord latéral correspondant de celles-ci.The position of the longitudinal members 6 to 9 on the crosspieces as well as the position of the crosspieces between them is made in such a way that two adjacent crosspieces are spaced apart by at least 8 mm and that the elements 6 to 9 are arranged at a distance of between 5 and 20 mm from the corresponding lateral edge thereof.
Une fois assemblée, l'épaisseur de la structure 2 est inférieure à 2 mm à l'avant du pied et inférieure à 30 mm à l'arrière du pied. Une telle structure permet de pouvoir s'adapter à différents poids de coureurs, par simple changement de propriétés des matériaux utilisés, sans nécessiter de modifications sensibles de la structure.Once assembled, the thickness of the structure 2 is less than 2 mm at the front of the foot and less than 30 mm at the back of the foot. Such a structure makes it possible to adapt to different weights of runners, simply by changing the properties of the materials used, without requiring significant modifications of the structure.
La forme des traverses et l'articulation de celles-ci par l'intermédiaire des éléments longitudinaux permettent d'assurer de bonnes propriétés d'amortissement, de maintien, de stabilité et de restitution d'énergie par l'intermédiaire d'une structure unique.The shape of the crosspieces and the articulation thereof through the longitudinal elements ensure good damping properties, maintenance, stability and restitution of energy through a single structure .
Comme il va de soi, l'invention ne se limite pas aux seules formes d'exécution de ce système, décrites ci-dessus à titre d'exemples, mais elle embrasse au contraire toutes les variantes. C'est ainsi notamment que les éléments longitudinaux pourraient venir de moulage en une seule pièce, que la chaussure pourrait ne pas comporter de semelle intermédiaire ou de semelle intérieure ou que la structure ne s'étende que sous une partie du pied, par exemple à l'avant ou l'arrière. As goes without saying, the invention is not limited to the embodiments of this system, described above as examples, but it encompasses all variants. It is thus in particular that the longitudinal elements could come from molding in one piece, that the shoe could have no midsole or insole or that the structure extends only under a part of the foot, for example to the front or the back.
