Features:

• Techno-Polymer Blade - Advanced materials provides the strength of bone to maximize power, speed & efficiency, while being extremely lightweight & durable.
• Power-X System - This revolutionary material acts as tendon & joint, optimizing propulsion by flexing during the downstroke and releasing stored energy prior to the upstroke.
• Power Channel - The flexible center channel simulates the elasticity of skin by directing water flow off the back of the blade for increased thrust.
• Soft-Pad Heel Strap - Our newly designed heel strap has a comfortable and ergonomic finger-loop which allows the fin to be easily removed & replaced, even with thick neoprene gloves.
• Easy Buckle Adjustment (EBA) - Our unique EBA buckle adjustment system allows for more than 2" (5 cm) of precise adjustments for a custom fit without tools.

Details: The revolutionary design of the Oceanic Manta Ray fin was inspired directly from the shape and bio-mechanics of marine animals. By combining three different materials to simulate bone, tendon and fin, we've created a blade design that provides maximum power, speed & efficiency while also remaining extremely lightweight & durable. Of course, it's not all nature's technology, we added some of our own as well. Our new soft-pad heel spring strap has a unique ergonomic finger-loop that makes getting these fins on or off in any situation a snap.
