• Document EP-A-560698 describes a sports shoe whose front part of the sole has a certain degree of mobility relative to the rear part, thanks to a stiffening element allowing a slight pivoting movement around a vertical axis .
• the sole has a central axis of support on the ground, having a curvilinear profile, in particular in the shape of an S.
• a first object of the invention consists in making a multidirectional lug sole making it possible to improve the stability, comfort and attachment of the shoe.
• a second object of the invention consists in making a molded studded sole having very reduced wear.
• the front face of the front part of the sole comprises a first series of spikes extending along a first curve substantially perpendicular to the axis, and having a radius of curvature greater than that R1 of the conjugate internal surface of the front of the sole,
• the rear face of the heel comprises a second series of studs staggered along a second curve substantially perpendicular to the axis, and having a radius of curvature greater than that R2 of the internal conjugate surface of the heel.
• protruding studs on the majority of the periphery of the sole provides excellent stability and optimum hooking on slopes.
• the distribution of the studs on the external attachment surface follows the curvilinear course of the foot along the median axis of support of the sole.
• the internal lateral face of the sole comprises at the front a convex part furnished with crampons, and at the rear a concave part devoid of crampons.
• the molded sole according to the invention can be in one piece, or be made in two elementary parts joined to one another by fixing means. 3 Brief description of the drawings
• FIG. 1 is an elevational view of a shoe with an upper equipped with a sole according to the invention
• FIG. 2 shows a perspective view of the sole and the covering member
• FIG. 8A is an enlarged view of a spike of the front sole element of Figure 8.
• FIG. 8B is an enlarged view of a crampon of the rear sole element of Figure 8;
• FIG. 11 shows a schematic top view of the sole of a left shoe
• - Figure 12 is an identical view to Figure 11 for a right shoe sole;
• FIG. 13 shows a sectional view through the front part of the shoe.
• a shoe 10 comprises a upper 12 mounted on a sole 14 molded with studs 16.
• the sole 14 is subdivided into a first anterior sole element 14A, and a second element of 4 rear 14B sole, constituting two separate front and rear parts obtained by molding an elastomeric or rubber-based material.
• a convex flap 18 is arranged at the front of the first sole element 14A going up on the upper face of the rod 12.
• the studs 16 are formed by studs coming from molding with the sole elements, and distributed over the majority of the lower surface between the flap 18 and the connecting face 20.
• the second rear sole element 14B comprises a collar 22 for holding up the rear of the upper 12.
• the entire lower surface of the second sole element 14B is fitted with studs 16, except the connecting face 24 disposed in the central zone opposite the other adjacent connecting face 20.
• the longitudinal offset e2 between the two sole elements 14A, 14B is adjusted in the central zone and the covering member 26 is straddled to cover said offset e2.
• the covering member 26 can be constituted by a flexible or semi-flexible retaining strip, having a high mechanical resistance, and a good resistance to abrasion.
• This strip can be assembled by bonding or vulcanization to the connecting faces 20, 24, and is made of a material having components compatible with the material of the sole 14. Additional attachment studs 27 can be provided on the underside, and on the opposite lateral faces of the covering member 26.
• the strip can also be shaped according to an interchangeable plastic collar depending on the desired mechanical rigidity.
• the covering member 26 can also be connected to the rod 12 by stitching means.
• the release of the two sole elements 14A, 14B takes place in two directions F1, F2 different oblique to the bearing surface of the sole 14 on the ground.
• the two directions F1, F2 form between them a predetermined obtuse angle as a function of the orientation of the studs 16 projecting from the two elements 14A, 14B.
• a pair of reduced-size molds is necessary for the manufacture of the two sole elements 14A, 14B, and it is possible to manufacture soles of different sizes, as shown in FIGS. 5 to 7.
• the sole 14 corresponds to a minimum size P1
• the connecting faces 20, 22 of the two sole elements 14A, 14B are located substantially in abutment along the longitudinal direction.
• the covering member 26 is separated from the first stud of the sole element 14A by a distance d1, and from that of the other sole element 14B by a distance d2.
• the sole 14 corresponds to the size P2 and to the longitudinal offset e2 from that of FIG. 6, but with a covering member 26 of length 12 greater than that 11 of FIGS. 5 and 6.
• the distances d1 and d2 are identical to those used for the sole of size P1 in FIG. 5.
• the sole elements 14A, 14B are standard for several shoe sizes, and a single set of molds is sufficient for the manufacture of the soles of a part of the range of shoes, with a low or rising upper. 6
• the lower profile of the first sole element 14A and of the second sole element 14B follows curves C3 and C4 representative of the natural winding of the foot during the stride.
• the length B of the second sole element 14B is greater than two thirds of the length A of the first sole element 14A.
• Such a dimensioning of the sole 14 takes account of the distribution of the loads, given that 55% of the weight is transmitted to the shoe in the tibia-fibula axis.
• FIGS. 8A and 8B at least some of the studs 16 situated under the lower surface of the first sole element 14A are shaped according to studs 30 each having a straight rear edge 32, substantially perpendicular to the connecting face 20, and an edge anterior 34 oblique.
• the stud 36 of certain studs 16 of the second sole element 14B is provided with an oblique rear edge 38, and a straight front edge 40.
• Each stud 30, 36 advantageously comprises a fastening imprint 42, 44 formed under the bearing face of the crampon.
• the lateral wings of the covering member 26 are extended upward to form a collar 46 for retaining the forefoot.
• the collar 46 surrounds the entire periphery of the front part of the rod 12, and comprises at the top adaptation means 48 of a device for tightening the rod 12.
• the collar 46 is additionally equipped with a bracelet 50 horizontally surrounding the rod 12 at the ankle to form a Y-shaped holding device.
• the effect of horizontal and vertical strapping of the rod 12 due to the presence of the collar 46 associated with the bracelet 50 makes it possible to obtain optimum immobilization of the foot relative to the sole 14.
• the front part of the first sole element 14A of a shoe on the left is slightly curved inwards, so as to optimize the support in pronation when walking.
• the heel of the second sole element 14B is oriented towards the outside to benefit from stable support with the ground following the supine effect of the foot.
• the profile of the shoe follows the central axis 52 of support of the sole 14 on the ground, said axis 7 being curvilinear in the shape of an S.
• the first series of studs 16 on the front face of the first sole element 14A extends along a first curve C1 substantially perpendicular to the median axis 52.
• the second series of spikes 16 on the rear face of the second sole element 14B extends along a second curve C2 perpendicular to the median axis 52.
• the distribution of the spikes 16 on the lower surface of the sole 14 also follows the curvilinear course of the foot during a stride.
• the internal lateral face of the sole 14 has a convex part 54 furnished with spikes 16 at the first sole element 14A, and a concave part 56 devoid of spikes at the second sole element 14B.
• the external radius of curvature of the first curve C1 of the front studs is greater than the internal radius of curvature R1 of the front of the " sole 14.
• Figure 12 is an identical view to Figure 11 for a sole of a right foot.
