Abstract
In a swim fin, members are provided for maintaining a swimmer's foot in fixed angular relationship with respect to the swimmer's leg, particularly during a downward kick or leg extension mode. The ankle is substantially locked in one position, and stress that would be placed on the ankle in the utilization of a prior swim fin is transmitted to the leg. In one embodiment, a rigid member extends from the foot-receiving portion of the fin to engage the swimmer's lower shin. Straps maintain the swimmer's leg and foot in fixed relationship to the swim fin. Adjustable members may be provided for adjusting the selected, fixed angular relationship between the swimmer's foot and leg.
