Featuring patented OPB hinge technology for easy and comfortable kicking as well as Channel Thrust for excellent performance with minimum effort. Soft, elastic heel straps attach with the quick release buckle system allowing for one-time adjustment and easy donning and doffing.
OPB – Optimized Pivoting BladeAllows the blade to maintain an optimal angle throughout the kicking cycle, whereas traditional fins achieve this only during a small portion of the cycle. OPB produces a constant thrust, which minimizes fatigue and produces fluid movement through the water.
Channel ThrustSoft longitudinal inserts allow a controlled deformation of the fin blade while kicking. This channel shape moves a greater amount of water resulting in more thrust for the same effort.
Quick Release BucklesA system of buckles exclusive to Aquazone which allow quick removal and adjustment of fins.
