Torelli Serpent Sportsman Fins are a moderate stiffness thermoplastic free diving fin very suitable for general spearfishing. The foot pocket tendons give the blade good support without adversely affecting its flex pattern and the stiff sole of the Serpent foot pockets enhances power transfer to the blade. The upper part of the foot pocket is soft and comfortable with a strip of harder material running across the top of the foot pocket ensuring efficient power transfer to the blade on the down stroke. The new long, narrow blade design eliminates wasteful side skid and enhances the water flow. An added benefit of the reduced blade width and eliminated side skid means that the fins rarely strike each other during the stroke cycle.
