Abstract:
A swim fin, comprising a footpocket (1) and a propelling blade (2), which has a central longitudinal member for supporting and stiffening the blade, substantially extending from a tip portion of the footpocket (1) to a free end edge (4) of the blade (2), thereby dividing the blade (2) into two half-blades, characterized in that the blade (2) has at least one pair of additional stiffening members (5, 5â€²), which are relatively rigid but resilient, each of which extends over a half-blade and branches off from the central longitudinal member (3) to the corresponding side edge (6) of the half-blade, the rest of the blade (2) being at least partly closed by at least one waterproof element, having a higher resiliency than the ribs (5, 5â€²).
