Footwear

Abstract

A concave portion ( 31 ) for reducing the weight load of the wearer acting on the big toe (f 1 ) is formed at a region in an insole ( 3 ) of a shoe ( 1 ). The region corresponds to a first site ranging from the ball (f 1 a ) of the big toe (f 1 ) to the tip of the toe. Further, at a region corresponding to a second site adjacent to the heel side of the ball of the big toe (f 1 a ), a pressing portion ( 32 ) is formed for pressing the second site, so that the reaction force occurring by the pressing causes the first site to sink in the concave portion ( 31 ).

1 . Footwear comprising:
 a concave portion formed at an insole at a position corresponding to a first site ranging from a ball of a big toe to a tip of the toe for alleviating a weight load of a wearer acting on the big toe; and   a pressing portion formed at the insole at a position corresponding to a second site being adjacent to a heel side of the ball of the big toe for pressing the second site, a reaction force occurring by the pressing causing the first site to sink in the concave portion.   
     
     
         2 . The footwear according to  claim 1 , further comprising
 a lifting portion formed at the insole at a position corresponding to four toes except for the big toe, for lifting the four toes.   
     
     
         3 . The footwear according to  claim 2 , wherein
 the lifting portion is formed to become gradually high from a second toe toward a small toe both included in the four toes, to cause a straight line connecting top ends of the four toes to be substantially horizontal.   
     
     
         4 . The footwear according to  claim 3 , wherein
 the lifting portion is provided with a projecting portion at the insole at a position corresponding to a clearance between a third toe and a fourth toe both included in the four toes, for widening the clearance.
