Shoes

Abstract

The present invention provides a shoe that improves a series of motion of the foot at the time of running and walking and reduces the shift of the foot from side to side. Shoe ( 100 ) of the present invention includes heel side support line part ( 101 ) arranged from the outer side of a heel part to the inner side of the heel part via a sole side. Heel side support line part ( 101 ) is an elastic member. Heel side support line part ( 101 ) has outer end part ( 101 A) arranged within the region posterior to the front end of the lateral malleolus, anterior to the virtual plumb line extending through the midpoint between the virtual plumb line passing through the most projecting point of the lateral malleolus and the virtual plumb line passing through the rear end of the calcaneus, and below the lower end of the lateral malleolus. Heel side support line part ( 101 ) has inner end part ( 101 B) arranged within the region posterior to the first metatarsal head, anterior to the front end of the medial malleolus, and below the lower end of the medial malleolus. Heel side support line part ( 101 ) is configured to apply the force to turn the foot in the direction of pronation by its elastic force to at least the heel part.

 a foot front side support line part arranged from a front inner side of a foot front part to a rear outer side of the foot front part via an instep part,   the foot front side support line part is an elastic member,   the foot front side support line part has an inner end part arranged such that at least its tip part is connect to the sole side within a region posterior to a midpoint of a first proximal phalanx in a major axis direction and anterior to a rear end of the first metatarsal head,   the foot front side support line part has an outer end part arranged within a region posterior to a midpoint of a fifth metatarsal bone in a major axis direction, anterior to a proximal end of a cuboideum bone, and at an outer side of an inner side edge of a fourth metatarsal bone, and   the foot front side support line part is configured to apply a force acted on the foot from a rear outer side to a front inner side by its elastic force to at least the foot front part.   
     
     
         3 . The shoe according to  claim 1  or  2 , wherein
 the outer end part of the heel side support line part is fixed to the shoe, and 
 the inner end part of the heel side support line part is attachable to and detachable from the shoe. 
 
     
     
         4 . The shoe according to  claim 2  or  3 , wherein
 the inner end part of the foot front side support line part is fixed to the shoe, and 
 the outer end part of the foot front side support line part is attachable to and detachable from the shoe. 
 
     
     
         5 . The shoe according to  claim 1 , wherein
 the inner end part of the heel side support line part has an adjustable attachment/detachment position to the shoe.   
     
     
         6 . The shoe according to  claim 2 , wherein
