Use the Da Fin Surf Swim Fin for recreational or professional use, made to give you a comfortable and contoured fit to your foot every time. Features Lightweight and floats in the ocean. Can be worn on either foot. Ultra-comfortable foot pocket. Balanced double density rubber for the perfect 'snap'. "Strakes" improve maneuverability and support against the heaviest surf. Side rails are rock solid, forcing the fin to flex right at the critical point. The V-shaped foot pocket and stiff blade work together at the point of flex to create maximum acceleration, resulting in more thrust per kick with less effort.
