Shoe outsole for decreasing knee adduction moment

Abstract

The present invention relates to an outsole for decreasing a knee adduction moment that has a front foot portion and a rear foot portion having different inclined angles corresponding to the knee adduction moments generated differently during walking operations in which a user's outsole contacts the ground, that is, standing, grounding and jumping operations, so that the knee adduction moments are decreased in accordance with the characteristics of the walking operations, thus adjusting bow legs or knock-knees, releasing and further preventing the pain of the knee joints, efficiently releasing the impact applied to the knee upon climbing mountains, and maintaining stable posture upon golf swing operation.

1 . An outsole  10  of a shoe  1  for decreasing a knee adduction moment, the outsole  10  comprising:
 a front foot portion  100  formed on a front portion thereof as a region corresponding to the front portion of a user's foot; 
 an intermediate foot portion  200  extended from the front foot portion  100 ; and 
 a rear foot portion  300  extended from the intermediate foot portion  200 , as a region corresponding to the rear portion of the user's foot, 
 wherein at least one of angles between the inner and outer surfaces of at least a portion of the longitudinal sections of the front foot portion  100  and the rear foot portion  300  and the outside ground of the outsole  10  is not formed at 90°, while an angle between any one side surface of the inner and outer surfaces and the outside ground of the outsole  10  is being smaller than the angle between the other side surface opposite to one side surface and the outside ground of the outsole  10 , and wherein a maximum value in the angles between the inner surface of the front foot portion  100  and the outside ground of the outsole  10  is different from a maximum value in the angles between the inner surface of the rear foot portion  300  and the outside ground of the outsole  10 , and a maximum value in the angles between the outer surface of the front foot portion  100  and the outside ground of the outsole  10  is different from a maximum value in the angles between the outer surface of the rear foot portion  300  and the outside ground of the outsole  10 . 
 
     
     
         2 . The outsole according to  claim 1 , wherein a space portion  30  or a low hardness member  31  having lower hardness than the outsole  10  of the shoe  1  is formed on or insertedly or exchangedly attached to one side surface of at least a portion of the longitudinal surface of the front foot portion  100  or the rear foot portion  300  in a direction of one side surface having the small angle in the angles between the inner and outer surfaces of the longitudinal section of the front foot portion  100  and the outside ground of the outsole  10 . 
     
     
         3 . The outsole according to  claim 1 , wherein at least one of angles between the inner and outer surfaces of at least a portion of the longitudinal section of the front foot portion  100  and the outside ground of the outsole  10  is smaller than 90°, an angle between any one surface of the inner and outer surfaces of the front foot portion  100  and the outside ground of the outsole  10  is smaller than an angle between the other side surface opposite to one side surface and the outside ground of the outsole  10 , and both side surfaces of the longitudinal section of the rear foot portion  300  are not inclined in the same direction as one side surface having the small angle in the angles between the inner and outer surfaces of the longitudinal section of the front foot portion  100  and the outside ground of the outsole  10 . 
     
     
         4 . The outsole according to  claim 3 , wherein a space portion  30  or a low hardness member  31  having lower hardness than the outsole  10  of the shoe  1  is formed on or insertedly or exchangedly attached to one side surface of at least a portion of the longitudinal surface of the rear foot portion  300  in a direction of one side surface having the small angle in the angles between the inner and outer surfaces of the longitudinal section of the front foot portion  100  and the outside ground of the outsole  10 . 
     
     
         5 . An outsole  10  of a shoe  1  for decreasing a knee adduction moment, the outsole comprising:
 a front foot portion  100  formed on a front portion thereof as a region corresponding to the front portion of a user's foot; 
 an intermediate foot portion  200  extended from the front foot portion  100 ; and 
 a rear foot portion  300  extended from the intermediate foot portion  200 , as a region corresponding to the rear portion of the user's foot, 
 wherein a high gravity member  501  is insertedly or exchangedly attached to at least a portion of the front surface and at least a portion of the outer surface of the front foot portion  100  of the outsole  10  or an upper  20  of the shoe  1 , and a space portion  502  or a low gravity member  503  is formed on or insertedly or exchangedly attached to at least a portion of the rear surface and at least a portion of the inner surface of the rear foot portion  300  of the outsole  10  of the shoe  1 . 
 
     
     
         6 . The outsole according to  claim 1 , wherein the angle between the inner surface of the longitudinal section of the front foot portion  100  and the outside ground of the outsole  10  is smaller than the angle between the outer surface of the longitudinal section of the front foot portion  100  and the outside ground of the outsole  10 , so that the outsole is worn for a user having bow legs. 
     
     
         7 . The outsole according to  claim 1 , wherein the angle between the outer surface of the longitudinal section of the front foot portion  100  and the outside ground of the outsole  10  is smaller than the angle between the inner surface of the longitudinal section of the front foot portion  100  and the outside ground of the outsole  10 , so that the outsole is worn for a user having knock-knees. 
     
     
         8 . An outsole  10  of a shoe  1  for decreasing a knee adduction moment or a knee abduction moment, the outsole comprising:
 an outward or inward moving member  504  or an outward or inward moving space portion or member  505  from the center of the repulsive force of the underside of the outsole  10  against the ground fixedly or exchangedly attached to at least a portion of the underside surface of the outsole  10  contacted with the ground or formed integrally with the outsole  10  in such a manner as to be located eccentrically toward the outer or inner surface of the outsole  10 .
