Abstract
A swim fin having an elongated flexible blade. The blade has elongated tapered sleeves to hold elongated tapered battens. The battens selectively stiffening the blade to achieve varying degrees of stiffness according to the wear's strength. Each batten has a tab to function to prevent the batten from sliding entirely within the sleeve and to function as a grip for easy removal of the batten from the sleeve. Additionally, the fin has ribs with concave outer walls which assist in the smooth flexing of the fins when used.
