The new OPB (Optimized Pivoting Blade)
patented system in a lightweight and high-performance
full-foot fin.
- Blade with OPB system to optimize the lift angle during
the fining action. 30% improved performance compared with
traditional fins.
- Rib edges and blade tips in soft, thermoplastic rubber,
for greater resistance against fatigue.
- Soft, orthopedic foot pocket, for greater comfort and
efficiency.
- Stabilizers, for greater stability and torsional
stress reduction on the ankle during the fining action.
- O.P.B. (Optimized Pivoting Blade).
During the finning stroke, the structure of traditional
fins tends to limit the flexing angle of the blade. As a
result, and especially during the downward kick, only a
small portion of the blade pushes the water in the
direction of motion, while the remaining part pushes the
water in the opposite direction.
The O.P.B. system, patented by Mares, ensures that the
blade is always at an optimal angle during both the
upward and downward strokes, thus considerably increasing
efficiency. This ensures that all the divers muscular
effort translates into effective thrust in the direction
of motion.
Another limitation of traditional fins is the degradation
of the thrust produced during the finning stroke,with
substantial differences between the maximum and minimum
values. The O.P.B. system, on the other hand, ensures
optimal thrust throughout every phase of the finning
stroke, thereby minimizing fatigue and affording much
more fluid movement through the water.
The O.P.B. system also makes it possible to virtually
eliminate the dead angles which normally exist when using
traditional fins.
