Footwear

Abstract

To provide footwear, in which a cushion layer is effectively bent even though an outsole of footwear has a thick cushion layer to distribute weight, thereby putting no stain on movement during walking, the footwear according to the disclosure includes uppers provided to surround at least a certain region of a wearer's foot; a supporter disposed below the uppers and supporting the foot; and a walking assister provided in the supporter, adjacent to a metatarsophalangeal joint area of the foot, and generating elasticity in a walking direction of the wearer.

What is claimed is: 
     
         1 . Footwear comprising:
 uppers provided to surround at least a certain region of a wearer's foot;   a supporter disposed below the uppers and supporting the foot; and   a walking assister provided in the supporter, adjacent to a metatarsophalangeal joint area of the foot, and generating elasticity in a walking direction of the wearer.   
     
     
         2 . The footwear of  claim 1 , wherein
 the walking assister is compressed in mid-stance motion of the wearer, and restored in toe-off motion of the wearer.   
     
     
         3 . The footwear of  claim 1 , wherein
 the walking assister comprises a plurality of walking assisters provided below the metatarsophalangeal joint, and   the metatarsophalangeal joint is positioned between the plurality of walking assisters.   
     
     
         4 . The footwear of  claim 1 , wherein the walking assister is formed as a single body below the metatarsophalangeal joint. 
     
     
         5 . The footwear of  claim 1 , wherein
 the supporter comprises a mounting groove formed to cross the supporter in a widthwise direction of the supporter, and   the walking assister is mounted to the mounting groove.   
     
     
         6 . The footwear of  claim 5 , wherein the walking assister is provided to cross the supporter in the widthwise direction of the supporter, and formed to have a trapezoidal cross-section in the lengthwise direction of the supporter. 
     
     
         7 . The footwear of  claim 6 , wherein the walking assister comprises a material of which elasticity is high in the walking direction of the wearer. 
     
     
         8 . The footwear of  claim 5 , wherein the walking assister is shaped like a torsion spring. 
     
     
         9 . The footwear of  claim 5 , wherein the mounting groove is shaped to taper upward in its cross-section in the lengthwise direction of the supporter. 
     
     
         10 . The footwear of  claim 9 , wherein the walking the supporter comprises:
 a first frame area disposed to be adjacent to a front region of the mounting groove;   a second frame area disposed to be adjacent to a back region of the mounting groove; and   an elastic area connecting the first and second frame areas and generating elasticity between the first and second frame areas.   
     
     
         11 . The footwear of  claim 1 , wherein the walking assister assists the supporter in ordinarily bending a front region upward an angle of 10˜40° with respect to the metatarsophalangeal joint, and generates elasticity when the supporter is compressed by external force while touching the ground and then taken off the ground. 
     
     
         12 . The footwear of  claim 1 , wherein
 the supporter comprises an outsole disposed below the uppers; and a midsole disposed between the uppers and the outsole, and   the walking assister is provided in the outsole or both the outsole and the midsole.   
     
     
         13 . The footwear of  claim 1 , wherein the walking assister comprises:
 a first assister disposed frontward with reference to the metatarsophalangeal joint; and   a second assister disposed backward with reference to the metatarsophalangeal joint, wherein   the first assister and the second assister are different in angle at which the supporter is bent during the walking of the wearer.   
     
     
         14 . The footwear of  claim 13 , wherein
 the first assister allows the front region of the supporter to be bent at an angle of 15˜25°, and   the second assister allows the back region of the supporter to be bent at an angle of 45˜65°.   
     
     
         15 . The footwear of  claim 14 , wherein the first and second assisters are formed with a bottom side longer than a top side. 
     
     
         16 . The footwear of  claim 15 , wherein
 the bottom side of the first assister is lengthened in a frontward direction, and   the bottom side of the second assister is lengthened in a backward direction.
