  • Riddled Foot Pocket

    The perforations prevent stagnating water flow from slowing you down. Eliminating this “parachute effect” you’ll slide faster through the water. Furthermore the openings eliminate any suction effect, making doffing easier.

    OPB - Optimized Pivoting Blade

    Allows the blade to maintain an optimal angle throughout the kicking cycle, whereas traditional fins achieve this only during a small portion of the cycle. OPB produces a constant thrust, which minimizes fatigue and produces fluid movement through the water.

    Channel Thrust

    Soft longitudinal inserts allow a controlled deformation of the fin blade while kicking. This channel shape moves a greater amount of water resulting in more thrust for the same effort.

    Tri-Material Construction

    3 specific materials for maximum elasticity, high durability and resistance to aging. The result is superior performance in all diving conditions.
