Abstract
A walking shoe having a uniquely shaped platform along the rear peripheral edge of the insole, which is constructed of a rigid backpart material and flexible forepart material. By combining it with a construction of a specially molded outflange counter and using a sturdy stitched lasting construction fastening securely the outward flange of the counter with the specially lasted molded leather upper together with the outward extension of the specially shaped insole platform, a stable support system is formed to control the lateral and longitudinal orientation of the foot when walking.
