Abstract
A swim fin having a low drag profile foot pocket-beam assembly, achieved by attaching a single beam to the bottom of the foot pocket to support the rigid blade. Such construction has the added advantages of making it possible to taper the sides of the toe portion of the foot pocket to generally conform to the shape of the foot, reducing the drag profile of the foot pocket and positioning the single beam so-that it is behind the foot pocket during swimming, thereby improving swim fin efficiency.
