Abstract: An orthotic, for providing proper support for a patient's foot within a shoe has provided on its top and bottom surfaces closely spaced substantially parallel grooves. The grooves on the top surface control slippage of the foot across the orthotic while the grooves on the bottom surface of the orthotic control slippage of the orthotic relative to the shoe's insole. The orthotic is shaped from a single monolithic workpiece by guiding a computer-controlled milling tool along substantially closely spaced parallel passes in a preselected pattern across the workpiece to thereby produce the orthotic's surface contours and surface texture in a single operation.

Abstract: The low profile functional orthotic constructed of polypropylene and formed with a heel, arch and forefoot area terminating short of the metatarsals. The heel portion is formed with an integral heel post and the forefoot portion is contoured on the underside to form a flat downwardly facing forefoot support surface projecting in a plane which is intersected by the upper plantar support surface at the forward extremity of the orthotic.
