First fins in the world made by combining three different materials designed for deep skin-diving.
Incredibly reactive, lightweight polypropylene blades that progressively charge up during the stride to take off like a spring at the exact moment the stride is inverted.
Soft elastomer anatomically wraps around the foot, blocking it with a comfortable bite, which guarantees perfect transmission of the leg-fin thrust. A suitably solid copolymer hardens some critical zones of the foot, and is extended along the sides in two lateral stringers, which go halfway along the blade to regulate and harmonize the bending, at the same time protecting it from shocks and abrasions.
Can comfortably be worn with or without neoprene socks.
