Abstract
A swim fin including a foot pocket has a rigid blade pivotally attached to a spring-biased strut assembly, one end of which is attached to the toe of the foot pocket, the other end of which is attached to the leading edge of the rigid blade. In one form the swim fins are provided as a pair, the blade of one having its trailing edges inclined, the leading edge of the blade of the other fin having leading edges inclined to accommodate the trailing edge of the other fin. The hinge point of one fin is located farther from the toe of the foot pocket than is the case for the other fin so that the swim fins can be used without their blades striking each other. The structure requires a minimum amount of energy for blade angle reversal during swimming.
