ABSTRACT:
The specification herein shows a swimmer's fin having a foot pocket and a blade portion wherein the blade portion is offset from the foot pocket to compensate for the natural supination during a flutter kick, stroke or beat, regardless of whether or not it is a backstroke, kick, or a crawl stroke kick. The fin can be molded in a symmetrical manner so that it can be interchanged between the feet and provided with an offset ankle strap in order to create a more comfortable relationship during the swimming movement. The fin also includes an improved blade end having inner and outer curves wherein the outer curve from the body is of a larger radius than the inner curve. The offset of the foot pocket from the blade can be such wherein the axis of the blade and the axis of the foot pocket intersect within the foot pocket area to provide for improved performance.
