High-heeled shoe sole structure and high-heeled shoe including same

Abstract

The present invention discloses a sole structure of a high-heeled shoe that may have a walking mechanism similar to movement of human walking when a pedestrian wears and walks in high-heeled shoes. A sole structure of a high-heeled shoe of the present invention includes: a front portion supported on the ground; a bending portion that extends from the front portion to be positioned at a rear side of a metatarsophalangeal joint and is bent in an opposite direction to the ground; and a rear portion extending from the bending portion.

1 . A sole structure of a high-heeled shoe, comprising:
 a front portion supported on the ground;   a bending portion that extends from the front portion to be positioned at a rear side of a metatarsophalangeal joint and is bent in an opposite direction to the ground; and   a rear portion extending from the bending portion.   
     
     
         2 . The sole structure of the high-heeled shoe of  claim 1 , wherein
 the bending portion includes a bending curved portion that forms a concave curve in an opposite direction to the ground.   
     
     
         3 . The sole structure of the high-heeled shoe of  claim 2 , wherein
 in the bending curved portion,   a curvature of a transverse center line of the bending portion that is parallel to a transverse axis of a foot and formed along a line crossing a longitudinal center line of the bending portion is larger than that of the longitudinal center line of the bending portion formed along a longitudinal axis of the foot.   
     
     
         4 . The sole structure of the high-heeled shoe of  claim 1 , wherein
 the bending portion is concavely bent in a direction opposite to the ground during heel off and toe off in a gait cycle, and is limited to be bent in a ground direction during a swing phase in the gait cycle.   
     
     
         5 . The sole structure of the high-heeled shoe of  claim 1 , wherein
 the bending portion is bent during heel off and toe off in a gait cycle such that the rear portion corresponds to foot movement in inversion and adduction directions of a foot.   
     
     
         6 . The sole structure of the high-heeled shoe of  claim 3 , wherein
 in the transverse center line of the bending portion,   a curvature of a lateral side portion is larger than that of a medial side portion.   
     
     
         7 . The sole structure of the high-heeled shoe of  claim 1 , wherein
 in the bending portion,   a thickness of a lateral side portion is thicker than that of a medial side portion.   
     
     
         8 . The sole structure of the high-heeled shoe of  claim 1 , wherein
 the bending portion includes at least one or more bending adjustment holes or bending adjustment grooves that make degrees of bending of a medial side portion and a lateral side portion different.   
     
     
         9 . A high-heeled shoe provided with a sole structure,
 wherein the sole structure includes:   a front portion supported on the ground;   a bending portion that extends from the front portion to be positioned at a rear side of a metatarsophalangeal joint and is bent in an opposite direction to the ground; and   a rear portion extending from the bending portion.   
     
     
         10 . The high-heeled shoe of  claim 9 , wherein
 the bending portion includes a bending curved portion that forms a concave curve in an opposite direction to the ground.   
     
     
         11 . The high-heeled shoe of  claim 10 , wherein
 in the bending curved portion,   a curvature of a transverse center line of the bending portion that is parallel to a transverse axis of a foot and formed along a line crossing a longitudinal center line of the bending portion is larger than that of the longitudinal center line of the bending portion formed along a longitudinal axis of the foot.   
     
     
         12 . The high-heeled shoe of  claim 9 , wherein
 the bending portion is concavely bent in a direction opposite to the ground during heel off and toe off in a gait cycle, and is limited to be bent in a ground direction during a swing phase in the gait cycle.   
     
     
         13 . The high-heeled shoe of  claim 9 , wherein
 the bending portion is bent during heel off and toe off in a gait cycle such that the rear portion corresponds to foot movement in inversion and adduction directions of a foot.   
     
     
         14 . The high-heeled shoe of  claim 11 , wherein
 in the transverse center line of the bending portion,   a curvature of a lateral side portion is larger than that of a medial side portion.   
     
     
         15 . The high-heeled shoe of  claim 9 , wherein
 in the bending portion,   a thickness of a lateral side portion is thicker than that of a medial side portion.   
     
     
         16 . The high-heeled shoe of  claim 9 , wherein
 the bending portion includes at least one or more bending adjustment hole or bending adjustment groove that makes degrees of bending of a medial side portion and a lateral side portion different.
