Abstract
Path length L is a distance from the origin to the tip toe position along the sole top surface, intersection C is a point between the sole bottom surface and a line perpendicular to the reference line S through the position of 0.45 L, and intersection D is a point between the sole bottom surface and a line perpendicular to the reference line S through the position of 0.60 L. In a sole stable posture in which the sole is in contact with the ground at points C and D, the sole bottom surface is separated from the ground at the heel and tip toe portions. Inequality, θ≥5 degrees is satisfied in the sole stable posture, wherein θ is an angle between the ground and a line connecting the heel central position of 0.15 L and the metatarsophalangeal joint position of 0.68 L.
