- Fishing fin or 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
- Shovel molded in polypropylene with differentiated thickness: rear part 3.5mm thick, tip 1.8mm thick
- side members under the footbed

- The Pinna Speeder is the result of careful research on 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 shovel, we implemented the interaction between them through the improvement of the coupling system, effectively improving the overall functionality of the product.
- The fishing shoe is the element that unites the fisherman to the blade and it is through it that all the power is discharged on the blade to transform it into movement. For maximum efficiency of the Speeder fin, we have moved the side spars under the sole of the foot:
this has made it possible to greatly improve comfort and at the same time increase thrust with the same effort.
The side members 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 Scarpetta a particular shape with variable thicknesses for
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 an excellent transfer of energy from the diver to the shovel.
- The blade is molded in polypropylene: to ensure the best propulsive thrust
and an excellent springback while minimizing the kicking effort the blade was
made with differentiated thickness: while the toe has a thickness of 3.5mm on the heel
has a thickness of 1.8 mm
