Mares' high-efficiency open heel fin for long dives. The pivoting blade holds a steady angle through the whole kick, and a large center channel flanked by two side channels moves more water with less fatigue. The vented, ribbed foot pocket makes the fins easy to slip on and off, and the bungee strap resists sun, salt and chlorine.
