Definitions

  • the subject of the present invention is a sole, in the field of shoes for professional use.
  • These shoes are usually made up a flexible leather upper assembled on a flexible sole or semi-rigid.
  • a safety sole incorporating a plate forming a insert located at the middle of the sole or shank that extends substantially from the front of the heel to the rear of the front part of the sole and around which insert is molded said sole, said insert covering only part of the width of the sole.
  • the object of the present invention is to remedy this disadvantage by proposing a concept stem / sole ensuring better foot support, especially on uneven surfaces while maintaining the flex line natural of the foot.
  • the shoe thus described according to the present invention includes a molded wear bottom layer around an insert made of a material plate semi-rigid plastic located at the shank and a superior comfort layer and is characterized essentially in that it involves, in its part rear, a plastic buttress piece semi-rigid.
  • the wear layer will be made of polyurethane with a density between 0.8 and 1.2 and preferably about 1, and with a shore hardness between 60 and 70, preferably around 65 and the wear layer is formed polyurethane with a density between 0.3 and 0.7, preferably around 0.5 and a shore hardness between 60 and 70, preferably around 65.
  • the semi-rigid plate forming the insert will have a shore hardness between 80 and 100, preferably about 90 shore A and has a shape overall rectangular whose dimensions are determined from so that it covers the entire width of the surface bottom of the sole at the shank extending on the sides of the sole. It can advantageously have crampons on its underside plastic, of a hardness lower than that of said plate, such as rubber.
  • the buttress piece surrounds the part rear of the sole from the heel to the middle part of the sole. Also its end posteriorly will advantageously include a zone of least thickness for better comfort of use of the shoe. It will have a shore hardness between 80 and 100, of preferably around 90 shore A.
  • a sole 1 of safety shoe according to the present invention comprises on the one hand a layer lower 10 or wear layer and an upper layer 11 or comfort layer molded above the layer lower 10 and on the other hand an insert 2 located under the sole 1, in a plane substantially parallel to its base and a buttress piece 3 located above the layer wear 10.
  • Insert 2 consists of a form plate rectangular in semi-rigid plastic and covers the entire width of the sole 1 at its part median or shank extending laterally on the sides of the sole up to the comfort layer 11 which goes back up to the shank and extending appreciably from the front of the heel 12 to the rear part 13 from the front of the sole 1.
  • the plate 20 of insert 2 has on its underside a series of rubber clamp 21.
  • the buttress piece 3 is also made from a semi-rigid plastic and has the V-shaped whose height decreases from the heel from sole 1, which it covers, up to the part sole of the sole 1.
  • the buttress piece 3 and the insert 2 will be preferably made from plastic materials polyurethane base and preferably a polyurethane tropicalized allowing better resistance to hydrolysis.
  • the buttress piece 3 will be secured to the shoe upper by gluing or stitching and insert 2 will be adjusted very tightly. Sole 1 will be molded on insert 2 and buttress piece 3.
  • the sole 1 of the present invention has a greater rigidity allowing to favor the natural dynamics of walking while avoiding all deviations of the foot during the course of the step and includes a additional protection at the rear of the foot against strokes, however keep the natural line of flexion of the foot and also help hold the ankle.
