The Oceanic Open Heel Viper 2 Fins are ready to propel all of your aquatic adventures. Ideal for any skill level but they still pack a punch with the performance and aesthetics of an elite model. The Viper 2 includes a precision blend of hydrodynamics for ultimate comfort, efficiency and performance. The Flexible Power Thrust Channel and enhanced channel rails direct water flow off the tips of the fin without allowing water to spill from the sides of the blade and now provide uncompromising power and efficiency at a great value. But Oceanic didn't stop there. Fins are manufactured from a composite material consisting of blended of thermal plastic rubber (TPR) and polypropylene. 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. Open Heel features easy adjust quick-release buckles. New features also include a polished blade and redesigned performance rails to give the Viper 2 a much-needed update. Also available in Full Foot Design (see SKU: OCNF2VPF). Fins are available in multiple sizes and colors.
