SALVIMAR Speeder spearfishing fins 41-42

Features: - Fishing fin for pure freediving consisting of foot pocket with incorporated insole and removable blade. - Ergonomic rubber foot pocket with differentiated thickness, excellent comfort. Rigid PP insole incorporated in the molding phase. - Polypropylene side clips fused to the side member blade molded in polypropylene with differentiated thickness: Rear portion 3.5mm thick, tip 1.8mm thick rails under the foot pocket. The Speeder Fin is the the result of careful research in the the dynamics of movement. - During the development phase, in addition to paying particular attention to the characteristics of the two components that make up a fin, foot pocket and blade, we implemented the interaction between them through the improvement of the coupling system, effectively improving the overall functionality of the product. - The foot-pocket is the element that unites the fisherman to the blade and it is through it that all the power is unloaded on the blade to transform it into movement. For maximum efficiency of the Speeder fin, we’ve moved the side rails under the sole of the foot: This made it possible to greatly improve comfort and at the same time increase the thrust with the same effort. The side rails are also equipped with internally fused side clips which guarantee excellent mechanical adhesion to the blade, avoiding steps and hydrodynamic turbulence. - We have also given the foot-pocket a particular shape with variable thicknesses to obtain a remarkable mechanical resistance of the material combined with lightness and rigidity: to a soft upper we have in fact combined a rigid insole incorporated in the molding phase which guarantees excellent energy transfer from the diver to the blade. - The blade is molded in polypropylene to ensure the best propulsive thrust and an excellent elastic return while minimizing the kicking effort, the blade has been made with variable thickness while in the heel it has a thickness of 3.5 mm the tip has a thickness 1.8 mm.
