Wave - Enjoy pure ease! - Another new entry in open heel fins, the Wave uses three material construction to apply specific properties where needed. The upper part of the foot pocket is especially moulded in soft rubber to guarantee the maximum comfort. The blade has big soft rubber insert perfect to get the ideal Super-channel water flow. The remainder has the rigidity and strength needed for superior propulsion.The Wave Fin from Mares has a soft rubber foot pocket, specific blade inclination and a large rubber Super-Channel which allows water to be propelled more efficiently down the fin blade providing superb performance with minimal effort.Superchannel. The blade has been designed with a large, flexible central super channel which propels water more efficiently down the fin blade instead of letting it spill over the sides for optimal performance and minimal diver effort. Channel thrust is inspired by marine mammals and this new technology maximizes the channelling of water and moves a much greater amount of water compared to other fins. This results in greater thrusting power but with the same amount of effort. ABS plus buckles allows quick opening and closing of the buckle even when wearing thick neoprene gloves. The double button release prevents the buckle from accidentally opening making it really user friendly. Open foot pocket provides maximum power and evenly distributes pressure over the foot to minimize tiredness. Internal ribbing inside the foot pocket improves fit and prevents foot suction and flexing of the foot pocket whilst transmitting great power to the blade. Tri Material construction provides superior performance, maximum elasticity, great durability and a resistance to aging.
