Small and light weight, yet extremely efficient, the Velocity Full Foot Fins feature our unique Power Enhancing Vents (PEV's) for reduced leg stress and increased velocity. During the fin stroke, water flow is directed through the PEV's. This helps reduce the stress on the diver's leg while accelerating water over the blade, resulting in increased velocity. Water movement through the PEV's reduce lateral movement of the fin (wasted energy), increasing the efficiency of the kick. <br><br> Made from advanced composite materials for ideal flex and memory, with an ergonomically designed foot pocket and weighing in at only 2.5 lbs. (1.13 kg) per pair, the Velocity Full Foot fins are the ideal Scuba or snorkeling fin for the traveler. Try a pair for yourself and find out what Aeris mean by designed for velocity. <br> These Fins are currently on closeout. These are the non-textured version.
