The S2 has been designed specifically for high performance bodyboarding, and is the benchmark in swimfin design.  It is crafted with 100% Malaysian Rubber, and has a soft asymmetrical foot pocket to produce a perfect fit. It also has a straightened blade for improved accelleration and helping to reduce twist to the ankles and knees. This fin has blade rail ridges and angled rails to transfer energy easily and efficiently. It also has a jet vent drainage system to keep the foot pocket free from sand and rocks.
