Mares X-Stream Open Heel Dive Fins
Riddled Foot Pocket
The perforations prevent stagnating water flow from slowing you down. Eliminating this “parachute effect” you’ll slide faster through the water. Furthermore the openings eliminate any suction effect, making doffing easier.
OPB - Optimized Pivoting Blade
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.
3 specific materials for maximum elasticity, high durability and resistance to aging. The result is superior performance in all diving conditions.
