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.

Abstract: A sandal having a multi-layer sole including an insole of mini-cell foam which takes a set conforming to the sole of the wearer's foot. A pair of straps have their remote ends anchored to the opposite sides of the sole assembly with portions of each looped about the foot and freely movable lengthwise of a pair of passages traversing the sole assembly interiorly of its shank portion to the extent necessary to grip the foot comfortably when the adjacent free ends of the straps are secured together in any selected overlapped relation.
