The Mares Quattro Excel Fins. Developed following numerous tests on new materials in the field and in the lab, and after lengthy computer simulations intended to improve the performance. In order to improve performance over the already legendary Avanti Quattro, three different materials were used.

Super Channel Thrust makes it possible to channel the water and optimize thrust in comparison to other fins of similar size. The elastic OPB system ensures that the blade is always at an optimal angle during both the upward and downward strokes, considerably increasing efficiency. The "whale fin" section in the foot pocket allows for greater transmission of power, with improved sensitivity when finning. The consequent advantage is greater thrust with the same effort.Of course, the straps feature Mares ABS (Adjustable Binding System), recognized worldwide as the best strap closure and adjustment system.
