Allows 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.

Soft 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.



CARE AND MAINTENANCE Any superficial abrasions on the blade, on the rubber parts and / or on the buckles are due to normal wear and tear and shall not affect the functioning of the product. Any marks and/or small imperfections on products made of carbon or other composite materials should be understood as an intrinsic characteristic of the material itself. Rinse thoroughly in fresh water after each use, allow to air dry in a shaded place. Never use toothpaste, surfactants, solvents, soaps (even if neutral), detergents, alcohol or hydrocarbons to clean the fins, as they could cause parts of the product to break. Keep away from oils, greases, suntan creams and lotions. Do not expose to direct sunlight or heat sources for extended periods of time. When storing, keep in a cool, dry place avoiding product’s distortions. Use with compatible Mares spare parts only.
