Shoe cushion and shock absorbing shoe comprising same

Abstract

Disclosed are a cushion for use in a shoe and a shock absorbing shoe having the cushion. The shock absorbing shoe includes: a sole having a lower surface thereof contacted with the ground; a cushion disposed above the sole; and an upper disposed above the cushion. The cushion includes: a rigid frame defining an inner region corresponding to the shape of at least a part of a foot of a wearer; and an elastic member supported by the frame and disposed in the inner region to support the foot of the wearer. The sole has a groove formed on an upper portion thereof in order to provide a deformation space for the elastic member.

What is claimed is: 
     
         1 . A shock absorbing shoe comprising a sole having a lower surface thereof contacted with the ground, a cushion disposed above the sole, and an upper disposed above the cushion,
 wherein the cushion comprises:   a rigid frame defining an inner region corresponding to the shape of at least a part of a foot of a wearer; and   an elastic member supported by the frame and disposed in the inner region to support the foot of the wearer, and   wherein the sole has a groove formed on an upper portion thereof in order to provide a deformation space for the elastic member.   
     
     
         2 . The shock absorbing shoe of  claim 1 , wherein the elastic member comprises a first elastic layer and a second elastic layer that are separated from each other and disposed above and below each other. 
     
     
         3 . The shock absorbing shoe of  claim 2 , wherein the elastic member comprises a rubber band wound on the frame across the inner region in a direction perpendicular to a lengthwise direction of the frame. 
     
     
         4 . The shock absorbing shoe of  claim 3 , wherein the rubber band is hollow inside. 
     
     
         5 . The shock absorbing shoe of  claim 1 , wherein the elastic member has a plurality of slits formed thereon in a direction perpendicular to a lengthwise direction of the frame. 
     
     
         6 . The shock absorbing shoe of  claim 5 , wherein the slits are formed at a certain portion to which the foot of the wearer is adhered. 
     
     
         7 . The shock absorbing shoe of  claim 1 , wherein a portion of the frame corresponding to an arch of the foot of the wearer is protruded upwardly. 
     
     
         8 . The shock absorbing shoe of  claim 1 , wherein at least some portions of a front portion and a rear portion in a lengthwise direction of the frame is curved upwardly. 
     
     
         9 . A cushion for use in a shoe, comprising:
 a rigid frame defining an inner region corresponding to the shape of at least a part of a foot of a wearer; and   an elastic member supported by the frame and disposed in the inner region to support the foot of the wearer.   
     
     
         10 . The cushion of  claim 9 , wherein the elastic member comprises a first elastic layer and a second elastic layer that are separated from each other and disposed above and below each other. 
     
     
         11 . The cushion of  claim 10 , wherein the elastic member comprises a rubber band wound on the frame across the inner region in a direction perpendicular to a lengthwise direction of the frame. 
     
     
         12 . The cushion of  claim 11 , wherein the rubber band is hollow inside. 
     
     
         13 . The cushion of  claim 9 , wherein the elastic member has a plurality of slits formed thereon in a direction perpendicular to a lengthwise direction of the frame. 
     
     
         14 . The cushion of  claim 13 , wherein the slits are formed at a certain portion to which the foot of the wearer is adhered. 
     
     
         15 . The cushion of  claim 9 , wherein a portion of the frame corresponding to an arch of the foot of the wearer is protruded upwardly. 
     
     
         16 . The cushion of  claim 1 , wherein at least some portions of a front portion and a rear portion in a lengthwise direction of the frame is curved upwardly.
