The Omer Stingray full foot fins fixed blades are characterized by their thermo-rubber foot pockets, and the 22 degrees angle between foot pocket and blade. With traditional scuba fin blades an angle between the heel of the foot and the calf of the leg remains when the leg is extended-to-kick. This angle causes a loss of propulsion. The 22 degree angled blade design accommodates for this anatomical characteristic and ensures maximum efficiency throughout the kicking cycle. The 22 degree angle results in optimizing the power of the push through the water relative to effort.
The use of thermo-rubber of two different stiffness compounds increases comfort over normal foot pockets. The blades of the Stingray are produced in a low-modular polypropylene material. Extending from the foot pocket are side rails which add stiffness to the blade and prevent water from “spilling" over the outer edge of the blade. The blade of the fin is also channeled. The side rails and channels focus the movement of water down the surface of the blade increasing power and stabilizing the fin. The foot pocket is equipped with a large rubber pull-tab making it easier to put on and take off the fins.
Available sizes: 39-40 (5-6), 41-42 (7-8), 43-44 (9-10), 45-46 (11-12), 47-48 (13-14), 49-50 (15-16). These sizes reflect European and US numbers stated on the foot pockets. The European size is correct, but the US size may not be accurate. It's important to use the stated sizes as a reference to the foot pocket only, not necessarily as to how it fits.
The Omer Stingray Fins are sold as a pair and covered by a 24 month limited warranty.
