ABSTRACT:
A rigid orthotic insert made of layers bonded to one another, with each of the layers being made of graphite fibers positioned parallel to one another. At least one of the inserts is made of several sections, with some of the sections having the fibers oriented at different angles, thus causing a desired pattern of transmission of forces through the insert.
