ABSTRACT:
Disclosed is a diving fin, securable about a swimmer's ankle, having a blade oriented at a propulsive angle independent of how the swimmer's toes are positioned. The blade can be positioned not to interfere with walking and wading. The blade and boot are lockably engageable, and are then rotatable to a locked deployed position wherein the blade projects past the swimmer's heel and in line with the swimmer's lower leg. In one embodiment, the blade has a connector and the boot has a hub lockably engageable therewith to attach or detach the blade. Thus, the boot can be worn without the blade. The engaged connector is upwardly rotatable behind the swimmer's leg. A strap secures the undeployed blade adjacent the leg. The connector is rotatable between the undeployed and deployed positions and is lockable in the deployed position. In one embodiment, the blade can wobble a few degrees when in the locked position. Releasable locking mechanisms are disclosed for keeping the blade attached to the boot and for limiting the orientation of the blade relative to the boot. Fasteners are disclosed for holding the blade in the undeployed position by its trailing end portion.
