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.

An orthotic insert assembly for use with a shoe having an insole, comprising:
- a post member for substantially stationary mounting in a heel portion of said shoe, said post member having an upper surface;
- a thin, substantially rigid plate member for engaging a plantar surface of a wearer's foot in said shoe and having a heel cup formed in a heel end thereof, said plate member being substantially free from attachment to said post member and having a lower surface on said heel portion thereof for resting in engagement with said upper surface of said post member;
- and
- ridge members extending along medial and lateral sides of said heel cup so as to form a bearing interface between said upper surface of said post member and said lower surface of said plate member which enables said plate member to pivot on said post member through a predetermined range of motion.

- a post member for substantially stationary mounting in a heel portion of said show, said post member having a generally concave upper surface;
- a thin, substantially rigid plate member for engaging a plantar surface of a wearer's foot in said shoe and having a heel cup formed in a heel end thereof, said plate member being substantially free from attachment to said post member and having a generally convex lower bearing surface on said heel portion thereof for resting in engagement with said concave upper surface of said post member;
- and
- a raised ridge formed on said upper surface of said post member and extending along medial and lateral sides of said heel cup so as to form a bearing interface with said convex lower surface of said plate member which enables said plate member to pivot on said post member through a predetermined range of motion.
