Abstract
A shoe having a uniquely shaped platform along the rear peripheral edge of the insole, which is constructed of a rigid backpart 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. The forepart of the shoe may be of moccasin. Strobel modified welt-type or other construction which provides varying degrees of flexbility.
