US 2010/0075554 A1 · SWIM FINS

Abstract

Swim fins that attach to the legs of a swimmer to aid movement through the water. In one example embodiment, a swim fin includes an upper support frame, a lower support frame, a lower blade attached to the lower support frame, and at least one hinge assembly connecting the upper support frame to the lower support frame. The upper support is configured to be generally positioned along and attached to the front of a swimmer's lower leg between the swimmer's knee and ankle The lower support frame is configured to extend, in a swimming position, from a position proximate the swimmer's ankle to a position beyond the end of the swimmer's foot. The at least one hinge assembly allows the lower support frame to be rotated upward from the swimming position to a walking position. The walking position enables the swimmer to walk barefoot on a surface without the lower support frame nor the lower blade substantially contacting the surface.
