Brand new design for this extremely effective and yet very easy to use fin.
Warning: Last items in stock!
The new THOR EBS fin has a peculiar and unprecedented structure that combines the two central ribs in high modulus polypropylene, very reactive and a central area of the thermoplastic rubber with a convex section, assembled in a polypropylene blade. Two lateral nozzles located in the area where bending starts release the associated negative forces and allow the use of two high response ribs. This combination causes a channeling and acceleration of water flow, which stabilizes and increases propulsion at equal effort.
Thickness of the blade of decreasing profile "spina di pesce" to improve the directionality of the flutter and achieve a greater inertia of the final part of the fin.
Foot Pocket reinforced in the upper area by a supplementary thickness and laterally by two prolongations of polypropylene from the upper to avoid the dispersion of energy in the process of transmission from the foot to the blade.
FOOT POCKET with three differentiated volumes, with the central area narrowed so that the foot remains firmly fixed inside and the transmission of the foot-paddle effort is direct and precise.
