The Viper 2 Full Foot 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 and now provide uncompromising power and efficiency at a great value. But we didn't stop there. New features also include a polished blade and redesigned performance rails to give the Viper 2 a much-needed update. Also available in Open Heel Design.
