The Speeder fin is the result of careful research into motion dynamics. The innovative foot pocket is reinforced with a rigid sole located under the ball of the foot. This allows for optimal energy transfer during finning.

The 29-degree angle, rigid sole, and the side rubbers that roll under the ball of the foot give the foot pocket an unparalleled mechanical structure. The ability to use very soft rubbers offers exceptional comfort during the development phase.

The foot pocket and the blade interact through the enhancement of the coupling system, improving the overall functionality of the product. The molded polypropylene blade ensures better thrust and exceptional spring minimization. The blade is made with differentiated thickness: the heel is 3.5 mm thick, and the tip is 1.8 mm thick.
