Abstract
A swim fin including a quick-release mechanism associated with the heel strap. The quick-release mechanism includes a lever and a link which are secured together and to the strap in such a way as to define an over center, toggle, lever arrangement whereby the effective length of the strap can be quickly and abruptly changed to allow easy entry or release of the foot of a swimmer from the foot receiving cavity of the fin.
