- A powerful fin by nature. Its rigid, robust blade is delicately balanced by the special elastic centre membrane, which is designed to channel water backward, giving more speed and power to get on top of the conditions.
- The angle of the blade - in relation to the foot pocket - is designed with efficiency in mind. As each stroke begins, the fin provides ample propulsion without straining the muscles.
- Rubber grip under foot pocket prevents slipping on deck or similar surfaces ．Underside foot pocket drain hole for water drainage.
- Quick release buckle makes putting on and pulling off easier and faster.
