Abstract

A biomechanical article of footwear constructed to assure proper control of pronation and supination of the wearer's foot during locomotion achieved primarily by coordinate action of an extended varus wedge molded into the inner side of the heel and arcuate ribs in the forward half of the outsole designed to collapse and expedite torquing and reduce shearing forces of the foot and leg during med-stance propulsion. These important features are supplemented beneficially by an insole assembly including a material which takes a set during initial use in conformity with load bearing surfaces of the foot, and raised areas of the sole assembly beneath metatarsal arch to aid uniform weight distribution, and by a toe crest. Additionally and importantly improved self-adjusting strapping is provided to hold the sole assembly to the foot. This strapping includes a toe-embracing loop designed to hold the forward end of the foot firmly between the lateral edges of the sole assembly while leaving other portions of the strapping free for adjustment longitudinally of straight open-ended passages extending crosswise of the sole assembly.
