Certain foot deformities may be corrected by attaching an orthopedic appliance (16) to the heel (12) of a shoe (10) to establish a moment in the shoe to cause rotation thereof in response to ground engagement of the appliance under the weight of the shoe wearer. The orthopedic appliance (16), for attachment to the bottom of the shoe, has a two sided relatively flat base (18) with one side (18a) attached to the shoe and the second side (18b) provided with an arrangement of a plurality of projecting ribs (22). Each projecting rib (22) is formed at an acute angle with respect to the second side (18b) of the base, and each projection has an undercut reduced cross-sectional area (28) in a direction of flexure at the attachment to the base. Encircling the projecting ribs is a stabilizing ring (20) that limits the compression of the projecting ribs (22) between the second side (18b) and the ground engagement and provides a fixed supporting surface. At the center of the projecting ribs (22) there is attached to the second side (18b) of the base a wear pad (24) for further limiting the compression of the projecting ribs.
