Abstract: A swim fin specifically designed for use by an amputee comprising a substantially planar, elongate flipper portion integrally formed with and extending from a receiving pocket adapted to be mounted to the end of a limb of the amputee. A pair of elongate straps are connected along a side of the receiving pocket, wherein the straps are specifically designed to wrap around the amputee's limb, being fastened by a pair of mating hook and loop pads on opposite ends of the straps, thereby effectively securing the swim fin to the amputee's limb.
