Shoe

Abstract

A shoe having a structure with excellent acceleration performance is provided. A shoe includes: a sole made of a soft material, which includes a ground contact surface and also includes a foot contact surface facing a side opposite to the ground contact surface; and an upper combined with the foot contact surface side of the sole. A thickness of the sole at a position corresponding to an MP joint of a wearer is different from a thickness of the sole at a position corresponding to the center of the heel such that an angle between the foot contact surface and the ground contact surface falls within the range of 8 to 16 degrees. Accordingly, a shoe having a structure that provides excellent feeling of acceleration is provided.

         10 . A shoe, comprising:
 a sole made of a soft material, the sole including a ground contact surface and also including a foot contact surface facing a side opposite to the ground contact surface; and   an upper combined with the foot contact surface side of the sole, wherein   a thickness of the sole at a position corresponding to an MP joint of a wearer is different from a thickness of the sole at a position corresponding to the center of the heel such that an angle between the foot contact surface and the ground contact surface falls within the range of 8 to 16 degrees.   
     
     
         11 . The shoe of  claim 10 , wherein the foot contact surface is flat at the forefoot portion of the sole corresponding to the toe side of a virtual line connecting the wearer's MP joint and the heel side of the virtual line connecting the wearer's MP joint is tilted forward from the midfoot portion to the rearfoot portion. 
     
     
         12 . The shoe of  claim 10 , wherein the sole includes an arch portion recessed upward in a midfoot portion. 
     
     
         13 . The shoe of  claim 10 , further comprising a reinforcement member that reinforces the midfoot portion of the sole and a rearfoot portion of the sole. 
     
     
         14 . The shoe of  claim 13 , wherein the reinforcement member extends continuously from the rearfoot portion to a position corresponding to an MP joint. 
     
     
         15 . The shoe of  claim 13 , wherein the reinforcement member includes a curled-up part that extends upward along a heel part. 
     
     
         16 . The shoe of  claim 15 , wherein the sole includes a curled-up part that extends upward along a heel part, and a height of the curled-up part of the reinforcement member is 1.0 to 2 times the height of the curled-up part of the sole. 
     
     
         17 . The shoe of  claim 10 , wherein a rear end part of the rearfoot portion of the sole has a curved shape, the lowest point being immediately below the center of the heel, the radius of curvature is 100 to 200 mm in a side view. 
     
     
         18 . The shoe of  claim 10 , wherein the maximum thickness of the rearfoot portion of the sole is 3 to 5 times the maximum thickness of a forefoot portion of the sole. 
     
     
         19 . The shoe of  claim 10 , wherein the sole includes a hollow part formed in the rearfoot portion.
