FOOTWEAR INSOLE

摘要

A human shoe sole or insole, sockliner or orthotic for insertion into a human shoe having a foot supporting upper surface including a first region for supporting at least the first, metatarsal head of the foot, and a second region surrounding the first region. The first region provides less resistance to downward motion than the second region, and includes a hollow or depressed area, sized and located to promote eversion of the first metatarsal head as the wearer moves from midstance through propulsive phase. Also provided human insole or orthotic for insertion into a human shoe having a bottom surface with a hard shell covering at least a heel portion of the bottom surface, which reduces the deformation of the footbed under load. The insole or orthotic may also include a series of grooves located to increase flexibility where necessary.
