Following extensive research and product development, Aeris isw proud to introduce the Velocity fin, designed with unique Power Enhancing Vents (PEV's). The PEV's do just that enhance the power of the fin.

Here's how: During the fin'stroke, water flow is directed through the PEV's. This helps reduce the stress on the divers 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.

Go try a pair for yourself and find out what we mean by designed for velocity.
