Abstract
A two-piece orthotic insert assembly. A post member is fixedly mounted in the heel end of a shoe, and has a generally concave bearing surface. A separate plate member is placed in the shoe so that the heel end thereof rests in the post, the heel cup of the plate member having a generally convex lower bearing surface which engages the concave bearing surface in the post member so as to permit a predetermined range of pivoting motion between the two pieces. The concave upper bearing surface of the post member defines a generally U-shaped bearing area which supports the rear foot portion of the plate at a predetermined angle for heel strike. Following heel strike, the plate member pivots so as to permit a controlled amount of pronation of the foot.
