<P>PROBLEM TO BE SOLVED: To provide a shoe sole provided with a heel having a structure of a sophisticated cushioning effect that can alleviate impact force due to a jolt upon landing and can convert repulsive force from ground into thrust to move from landing to kicking action smoothly in walking or running. <P>SOLUTION: In the shoe sole 2 having the heel 1, the heel 1 has a structure that the toe 3 of the shoe sole 2 is directed forwards and the reverse is directed backwards, and a slant face 6 from the back uppermost end 4 of the heel 1 to the rear lowermost end 5 of the heel 1 is assumed, and a region 7 above the slant face 6 is formed of a high bounce foam and a region 8 below the slant face 6 is formed of a low bounce foam. Due to this structure, impact due to a jolt from ground at a rear end part of the heel 1 when landing is minimized while at the same time gradually increasing in succession a repulsive force against the heel 1 from ground during transition to walking or running and maximizing the repulsive force from ground at the front end part of the heel 1, thus converting the repulsive force from ground into thrust to move from landing to kicking action smoothly. <P>COPYRIGHT: (C)2012,JPO&INPIT |
