Shoe

Abstract

Provided is a shoe including: a shoe sole member that includes a front member arranged on a front side of the shoe and a rear member arranged on a rear side of the shoe; and an interlocking member that interlocks the front member and the rear member.

What is claimed is: 
     
         1 . A shoe comprising:
 a shoe sole member that comprises a front member arranged on a front side of the shoe and a rear member arranged on a rear side of the shoe: and   an interlocking member that interlocks the front member and the rear member.   
     
     
         2 . The shoe according to  claim 1 , wherein,
 when the shoe is viewed from a bottom side, a rear edge of the front member projects rearward in an arc-shaped curve, or   the rear edge of the front member is recessed forward in an arc-shaped curve.   
     
     
         3 . The shoe according to  claim 1 , wherein
 a shape of outer edge of each of the front member and the rear member is symmetrical relative to a centerline passing through a center in a width direction and extending in a front-rear direction.   
     
     
         4 . The shoe according to  claim 1 , wherein
 the interlocking member comprises a connection body that connects the front member and the rear member separated from each other.   
     
     
         5 . The shoe according to  claim 4 , wherein
 the connection body comprises one or two or more of rod bodies extending in the front-rear direction, and   a cross section when at least one of the rod bodies is cut along the plane perpendicular to the front rear-direction has an elongated shape in a vertical direction.   
     
     
         6 . The shoe according to  claim 4 , wherein
 a flexural rigidity of the connection body is greater in a vertical direction than in the left-right direction.   
     
     
         7 . The shoe according to  claim 4 , wherein
 the connection body comprises two or more of rod bodies extending in the front-rear direction, and   the number of vertically-arranged rod bodies is larger than the number of laterally-arranged rod bodies.   
     
     
         8 . The shoe according to  claim 4 , wherein
 the connection body comprises three or more of rod bodies extending in the front-rear direction, and   a polygon with its vertices formed by the rod bodies has an elongated shape in the vertical direction in a cross section of the rod bodies cut along the plane perpendicular to the front-rear direction.   
     
     
         9 . The shoe according to  claim 1 , wherein
 the interlocking member has a plate-shaped material that is arranged along a bottom surface of the shoe sole member and connects the front member and the rear member.   
     
     
         10 . The shoe according to  claim 1 , wherein
 the front member and the rear member are separated from each other, and   a part of a rear portion of the front member and a part of a front portion of the rear member are vertically arranged, while being separated from each other.   
     
     
         11 . The shoe according to  claim 1 , wherein
 the shoe sole member further comprises an intermediate member arranged between the front member and the rear member,   the intermediate member is configured to separate the front member and the rear member from each other,   a part of a rear portion of the front member and a part of a front portion of the intermediate member are vertically arranged, while being separated from each other, and   a part of a front portion of the rear member and a part of a rear portion of the intermediate member are vertically arranged, while being separated from each other.   
     
     
         12 . The shoe according to  claim 1 , wherein
 the interlocking member comprises an interconnection member that is integrally molded with the front member and the rear member to connect the front member and the rear member, and   a minimum width of the interconnection member is smaller than a rear end width of the front member and a front end width of the rear member.   
     
     
         13 . The shoe according to  claim 12 , wherein
 the interconnection member comprises an extension part extending in the width direction between the front member and the rear member.   
     
     
         14 . The shoe according to  claim 1 , wherein
 the interlocking member comprises an insole.   
     
     
         15 . The shoe according to  claim 14 , wherein
 the insole has a symmetrical shape.   
     
     
         16 . The shoe according to  claim 14 , wherein
 the insole has a metatarsus portion projectedly curved upward in an arch shape, and   the insole is configured such that, when a load is applied to either one side in the width direction of the metatarsus portion from above, the opposite side of the insole protrudes upward.   
     
     
         17 . The shoe according to  claim 14 , wherein
 the insole has a metatarsus portion projectedly curved upward in an arch shape, and   a rigidity of a central part in the width direction of the metatarsus portion is higher in both side portions than in the width direction of the metatarsus portion.   
     
     
         18 . The shoe according to  claim 1 , further comprising an upper, wherein
 a portion that is at least a part of the upper and arranged over a central part in the front-rear direction of the shoe sole member is made of a fabric that reduces an area when a force is applied in an in-plane direction.   
     
     
         19 . The shoe according to  claim 3 , which is asymmetrical in appearance relative to a centerline passing through a center in the width direction and extending in the front-rear direction, when the shoe is viewed from above.
