ABSTRACT:
The swim fin has a rigid blade that is fixedly attached to the end portions of two flexible beams which are molded to the sides of the foot pocket and project therefrom. The flexible beams project forwardly and inwardly for a short distance so as to position the flexible beams behind the toe of the foot pocket as the swim fin moves through the water during swimming. The height of the flexible beams is reduced at a position near the leading edge of the rigid blade so that most of the flexing is confined to this position. The rigid blade is hollow and the end portions of the flexible beams are enclosed in the shell of the rigid blade.
