Shoe Sole with Shock Absorbing Capability

Abstract

A shoe sole includes: a sole unit defining at least one recess; at least one elastic body received in the recess and having a cellular structure that defines at least two levels of cells, the two levels of the cells being disposed one above the other, each of the cells defining a cell space therein; and a filler material that fills the cell space of each of the cells.

1 . A shoe sole with shock absorbing capability comprising:
 a sole unit defining at least one recess;   at least one elastic body received in said recess and having a cellular structure that defines at least two levels of cells, said two levels of said cells being disposed one above the other, each of said cells defining a cell space therein; and   a filler material that fills said cell space of each of said cells.   
   
   
       2 . The shoe sole of  claim 1 , wherein said sole unit includes an outsole that defines said recess, and a tread member attached to said outsole and covering a bottom side of said recess, said cellular structure having a surrounding wall that defines an inner space and that is disposed between and that is attached to said outsole and said tread member, and a plurality of interconnected webs that are disposed in said inner space and that are connected to said surrounding wall so as to define said cells. 
   
   
       3 . The shoe sole of  claim 2 , wherein said surrounding wall has two open ends that are opposite to each other in a horizontal direction, each of said open ends of said surrounding wall defining an opening, each of said webs extending between said open ends of said surrounding wall, each of said cells extending in the horizontal direction, said shoe sole further comprising an elastic film that is attached to one of said open ends of said surrounding wall so as to cover said opening of said one of said open ends of said surrounding wall. 
   
   
       4 . The shoe sole of  claim 1 , wherein said filler material is selected from the group consisting of gel, silicone, polyurethane resin, and soft rubber.
