With the introduction of split fins, one wonders if companys are ignoring those that still love their paddle fins. Oceanic hasn't forgotten and their Viper strap scuba diving fin is testament to that. Their precision blend of hydrodynamics and materials technology makes the viper fin so responsive and fast; it's scary. The flexible power thrust panels in the Viper's blade direct the water off of the fin tip which provides improved power and efficiency. Oceanic also engineered the side rails and channels to aid in directing the water to the fin tip without allowing water to spill from the sides of the fins which would otherwise compromise it's power and efficiency. The fin blade is oversized but extremely light weight for better performance ease of travel and less strain during kicking. The foot pocket is generous but streamlined to accomodate a wider range of foot sizes and styles of boots.
