Kick your watersport performance up a notch. Diving for secret treasures? Competing in fierce national games? Wherever your endless love for water and aquatics takes you, be sure to bring along your secret performance weapon: These new speed fins from Ivation. Developed under our professional-grade watersports label, Ivation Aqua, every detail from materials to design to construction was obsessed over - all to give you a literal leg up in any pool of water and in any need-forspeed environment. We didn't invent the idea of going fast, but we help you master it. Extended Sole Plate Among our fins' speed-focused features is a longer sole plate that displaces more water with every motion of your foot. In addition to adding thrust to your game, this design element requires less effort on your leg's part, ensuring foot strain relief. Adjustable Strap System For exceptional fit and swift donning and doffing without wasting precious time in action, the adjustable strap system can be worked with a simplified one-handed motion. The wider strap delivers ample hold to the back of your heel without slip. Contoured Foot Chamber While some swear by swim booties, others like to let their feet breathe. Whichever way you swing it, our Ivation Aqua fins have you covered: The contoured foot opening offers your feet improved, lasting comfort - with or without swim booties. Premium Polypropylene Ivation Aqua serves serious water aficionados. That's why you'll find these fins to boast a professional-grade construction of premium polypropylene materials. It ensures efficient energy transfer from your foot, resulting in the most drive per kick. Rotating Hinge Post With other watersport fins, you would lose some of the propelling motion due to your foot's shape at the end of the kick cycle. But with our rotating smooth-action hinge posts, your fins are kept perfectly angled throughout.
