High-heeled footwear

Abstract

A heel part is formed in a plate spring shape that is elastically and flexibly deformable in the vertical direction, and a front end adjacent portion thereof is buried and fixed in an outer sole more on a toe side than a section of arch of foot of a sole part of a high heel. A portion continuous with and behind the fixed portion is exposed from the outer sole and gradually spaced apart from a bottom face of the outer sole in a rearward direction and has a warp-curved part 3 B in an upward arch shape in a side view in a lower region of the section of arch of foot, and a buffer plate grounded during walking and standing is attached to the bottom face of the heel part in a position almost immediately below a rear end part of the outer sole.

What is claimed is: 
     
         1 . High-heeled footwear comprising a heel part, wherein
 the heel part is constituted in a plate spring shape that is elastically and flexibly deformable in a vertical direction, and   the heel part includes a front end adjacent portion in a longitudinal direction thereof buried and fixed in an outer sole of the footwear more on a toe side than a section of arch of foot of a sole part of the footwear, a portion continuous with and behind the fixed portion being exposed from the outer sole and gradually spaced apart from a bottom face of the outer sole in a rearward direction and having a warp-curved part in an upward arch shape in a side view in a lower region of the section of arch of foot, and an impact absorbing member grounded during walking or standing being attached to a bottom face of the heel part in a position almost immediately below a rear end part of the outer sole.   
     
     
         2 . The high-heeled footwear of  claim 1 , further comprising an auxiliary spring member, wherein the auxiliary spring member connects a top face adjacent to a rear end part of the heel part and a bottom face adjacent to the rear end part of the outer sole, and the auxiliary spring member is elastically and flexibly deformable substantially in the vertical direction. 
     
     
         3 . The high-heeled footwear of  claim 2 , wherein the auxiliary spring member is constituted by a plate spring convex-curved forward and substantially C-shaped in a side view, the auxiliary spring member has a top end part connected and fixed to a rear end part of a shank incorporated in the sole part of the footwear, and a second impact absorbing member is incorporated at a connecting part between the shank and the auxiliary spring member. 
     
     
         4 . The high-heeled footwear of  claim 2 , wherein the heel part and the auxiliary spring member are integrally formed from a single tabular blank. 
     
     
         5 . The high-heeled footwear of  claim 1 , wherein a wedge-shaped member adapted to restrict a flexure amount of the heel part is incorporated between the bottom face of the outer sole of the footwear and a top face of the heel part. 
     
     
         6 . The high-heeled footwear of  claim 3 , wherein the heel part and the auxiliary spring member are integrally formed from a single tabular blank. 
     
     
         7 . The high-heeled footwear of  claim 2 , wherein a wedge-shaped member adapted to restrict a flexure amount of the heel part is incorporated between the bottom face of the outer sole of the footwear and a top face of the heel part. 
     
     
         8 . The high-heeled footwear of  claim 3 , wherein a wedge-shaped member adapted to restrict a flexure amount of the heel part is incorporated between the bottom face of the outer sole of the footwear and a top face of the heel part. 
     
     
         9 . The high-heeled footwear of  claim 4 , wherein a wedge-shaped member adapted to restrict a flexure amount of the heel part is incorporated between the bottom face of the outer sole of the footwear and a top face of the heel part. 
     
     
         10 . The high-heeled footwear of  claim 6 , wherein a wedge-shaped member adapted to restrict a flexure amount of the heel part is incorporated between the outer sole of the bottom face of the footwear and a top face of the heel part.
