ABSTRACT:
The shoe accessory includes a platform for supporting a conventional shoe that is bendable in a manner corresponding to bending of a wearer's show during walking, etc. The shoe accessory's base has a convex or other non-planar surface that causes the shoe accessory to be stable in a longitudinal (heel-toe) direction, and unstable in a lateral (medial/lateral) direction. The non-planar surface may be defined by one or more ridge segments on the platform's bottom side. One or more straps are provided to temporarily secure the wearer's conventional shoe to the platform in a non-destructive manner. A generally U-shaped heel retainer may be provided adjacent a rear portion of the platform for receiving the heel of the shoe. The shoe accessory makes a flat-soled shoe laterally unstable while allowing for longitudinal stability and a naturalistic gait, and thus facilitates exercise of leg and foot muscles during normal walking, running, etc.
