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.
