Abstract

See full text

A footwear article includes a foot-attachment structure configured to attach to a foot, and longitudinally opposite front and rear ends. The footwear article further includes a downward-facing exposed sole surface. A cantilever extension, in a natural condition, adjoins the sole surface at a junction, and projects rearwardly and downwardly from the junction. The extension has a proximal end and a distal end that are longitudinally opposite each other. The extension is supported at only the proximal end. The extension is configured to elastically resist upward rotation of the extension toward the sole, and is configured to be pushed upward toward the sole by the upward force.
