X-stream Comfort, X-ceptional Efficiency • New foot pocket. No parachute effect        The limiting factors in traditional open heel foot pockets are their weight and the “parachute effect”. When finning, water gets into the space between the bootie and the foot pocket, creating drag like the air in a parachute. The perforations prevent this and have the additional benefit of making the foot pocket very soft and flexible. Furthermore, the suction effect which can make doffing of the fins cumbersome, is now forever a thing of the past. • Next generation OPB       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. It is an exclusivity of Mares fins. • New blade construction for less turbulence      Mares Design inspired by marine mammals. Channel thrust technology maximizes the channelling of water and moves a much greater amount of water compared to other fins of the same size. The result is greater thrusting power with the same amount of effort. The X-stream performance, comfort and lightweight design are the incredible result of sixty passionate years at the service of diving. The X-stream is truly a leap into the future, and changes forever how we envision the creation of a fi n. More than 2 years of resources, experiments and testing and four Mares patents all concentrated in one unique product.

So fast and responsive they're scary. Precision blend of hydrodynamics and materials technology for ultimate comfort, efficiency and performance. The VIPER blade's Flexible Power Thrust Channel directs water off the tip of the blade for improved power and efficiency. The engineered channels and side rails direct water flow off the tips of the fin without allowing water to "spill" from the sides of the blade for uncompromising power and efficiency. Ideal for all diving and snorkeling skill levels Flexible Power Thrust Channel directs water off the tip of the blade for improved power and efficiency Power Vents reduce stress while accelerating water over the blade Oversized blade produces increased thrust and propulsion Generous yet streamlined foot pocket fits a wide range of boot styles while significantly reducing drag Extremely lightweight for increased performance and ease of travel Easy adjust quick-release buckles.
