Definitions

  • the invention relates to a shoe intended for the practice of many sports as well as golf, running or walking.
  • Document FR 2 945 915 discloses a shoe extending between a toe and a heel and comprising an upper engaged with an outsole via a comfort sole interposed between the upper and the comfort sole.
  • the comfort sole and the outsole are attached to each other to form the sole of the shoe.
  • the periphery of an orthogonal projection of the comfort sole of such a shoe comprises a first concave portion ZI on the outer side of the foot and a second concave portion Z2 on the inner side of the foot, as illustrated in FIG. 1. These concave portions are located at the level of the arch of the foot.
  • the aim of the present invention is to provide an improvement in the performance of a shoe of the type mentioned above and in particular to provide a sole construction which promotes the landing of the foot of a supinator or pronator runner.
  • the invention relates to a shoe extending between a toe and a heel and comprising an upper engaged with an outsole via a comfort sole interposed between the upper and the comfort sole, the comfort sole and the outsole being fixed to each other to form a sole delimited by a periphery, characterized in that an orthogonal projection of the periphery of the sole has a radius at all points of curvature giving said orthogonal projection a convex curvature.
  • the invention makes it possible to avoid the loss of energy during the phases of transition of the foot on the ground.
  • the comfort sole consists of a sole base and a sole flank and may include a single or dual density EVA part.
  • the side of the comfort sole is provided with ribs allowing stiffening of said sole. This results in an additional stability effect, when used while running or walking.
  • Figure 1 is a bottom view of the sole of a shoe according to the prior art.
  • Figure 2 is a side view of a first embodiment of the invention.
  • Figure 3 is a top view of the comfort sole of the first embodiment of the invention.
  • Figure 4 is a bottom view of the comfort sole of the first embodiment of the invention.
  • Figures 5 to 9 are cross-sectional views respectively B 1-B2, C1-C2, D1-D2, E1-E2 and F1-F2 of the comfort sole according to the first embodiment of the invention .
  • Figure 10 is a perspective view of the comfort sole according to the first embodiment of the invention.
  • Figure 11 is a rear view of the comfort sole according to the first embodiment of the invention.
  • Figure 12 is a perspective view of the comfort sole according to a second embodiment of the invention.
  • Figure 13 is a side view of a third embodiment of the invention.
  • Figure 14 is a cross-sectional view G1-G2 of the third embodiment of the invention.
  • Figure 2 shows a shoe according to a first embodiment.
  • the shoe extends between a toe 1 and a heel 3 and comprises an upper 5 engaged with an outsole 7 via a comfort sole 9 interposed between the upper 5 and the outsole 7
  • the comfort sole 9 comprises a sole base 11 and a sole sidewall 13.
  • the sole base 11 comprises a face 15, called upper, open on the upper 5 and an opposite face 17, called lower, serving as a binding. to the outsole 7.
  • an orthogonal projection P of the lower face 17 of the sole base 11 has at all points a radius of curvature R conferring on said orthogonal projection P a convex curvature 19.
  • a width Z3 of the lower face 17 must, at the heel 3, be smaller than a width Z4 of said lower face 17, at the tip 1.
  • the width is counted perpendicularly to a longitudinal direction L of the comfort sole 9, between heel and toe. This width ratio thus makes it possible to control better contact with the ground when the foot is unrolled, to promote it and improve the dynamic phase of walking or running, on flat ground, downhill or uphill.
  • the comfort sole 9 comprises schoola
  • the ribs 21 can be asymmetrical. In the middle zone, between the heel 3 and the toe 1 of the shoe, they can be higher and longer in order to promote the maintenance of the arch of the foot.
  • the number of ribs is variable. Depending on the desired applications, they can also have different stiffnesses, different shapes or be made from different materials.
  • Figures 5 to 9 the outer surface 17 of the comfort sole 9 which is in contact with the wear sole 7 present in cross section, perpendicular to the longitudinal direction L, a flat 25 and a concave curvature of 27 going up from the flat 25 towards the flank of the sole 13.
  • the radius of the curvature 27 is favorably between 25 mm and 100 mm.
  • Figure 12 illustrates a second embodiment of the invention, which differs from the previous embodiment in that the comfort sole 9 is more flexible insofar as it is devoid of stiffening rib of the flank the sole 13.
  • the comfort sole 9 can follow a base line of the foot and does not include a sole flank 13 reduced to a bead 23.
  • the comfort sole 9 is preferably made of a material ensuring comfort and also hold of the foot, such as rubber or EVA.
  • the comfort sole 9 can also be made of PU (Polyurethane), or any other natural or synthetic foam. It can also be made from a material having elastic or viscoelastic properties such as an elastomer.
  • the outsole 7 is made of any synthetic or natural material providing the properties necessary for grip and resistance to wear.
