The Super Rocket Fin is the ultimate fin. It is one of the most popular of the original vented fins in North America. Over the years it has become very popular with professional divers and the military (Including Navy SEALs). The soft flexible rubber foot pockets prevent skin abrasions on the toes. Divers who have high insteps appreciate this fin’s design for the comfort. The blade is vented to increase the efficiency of the down-kick and to reduce stress on the ankles. The heavier and short fin blade is sought after by divers who must work inside confined areas. The rugged design of these fins is all rubber and they feature quick release buckles.
