ABSTRACT:
Apparatus for enhancing relative rotation between a substrate and a rotatable member. The substrate preferably comprises a pole of a leg support assembly in a stilt device, and the rotatable member preferably comprises a leg engagement assembly of the stilt device which engages a user's leg. The reinforcement member preferably operates as a spacer for the substrate, as well as to reduce wear between the substrate and an elongated member which couples the rotatable member to the substrate. A limit surface of the reinforcement member limits mechanical deflection of the elongated member and preferably comprises an annular sidewall of an aperture. A locking feature of the reinforcement member preferably comprises a tab which engages a channel in the substrate to maintain a desired axial orientation of the reinforcement member.
