Abstract
A sole reference posture is determined such that a straight reference line connects a toe-tip position and a rearmost end position of a sole top surface, a path length measured along the sole top surface from the origin of the rearmost end position to the toe-tip position is L, an intersection point of a sole bottom surface and a line crossing a position of 0.45×L and orthogonal to the reference line is position C, and the sole is in contact with the ground at position C. In the reference posture, the sole bottom surface is separated from the ground at a heel portion and a toe portion, and an inequality θ≥5 is satisfied, wherein θ is an angle between a straight line connecting a heel central position of 0.15×L with a metatarsophalangeal joints position of 0.68×L and the ground.
