High power has been designed right in to this fin from IST. Its rigid, robust blade offers delicate balance via a special elastic center membrane. Meanwhile, water is turbo charged and channeled backward, providing more speed and power. Also, the angle of the blade, in relation to the foot pocket, is a computer-aided engineering wonder. As each down stroke begins, the fin gives maximum propulsion without straining your leg muscles. Rubber grip under foot pocket prevents slippage, and there’s an underside drain hole to prevent water logging.
Its rigid, robust blade is delicately balanced by a special elastic centre membrane. Water is efficiently channeled backward, giving more speed and power to be on top of the conditions. The angle of the blade – in relation to the foot pocket – is also designed with efficiency in mind. As each down stroke begins, the fin provides ample propulsion without straining the leg muscle.
