Abstract

A shoe rim cushion can protect an Achilles tendon of a user from injuries caused by rubbing of a heel collar of a shoe against the Achilles tendon. The rim cushion can be secured to the back of a shoe without adhesives through an internal biasing that can pinch the rim cushion onto the back of the shoe. The rim cushion can cover the rim of the heel collar so that the rim is unable to rub against the Achilles tendon. The rim cushion can include a double shield with a semi-rigid inner brace and a resilient cushioning pad that can disperse forces applied by the rim to the Achilles tendon.
