High-Grade Material For reliability and durability that you can count on, the IST Rubber Rocket fins are the only true choice. Strong rubber material won't wear out or lose its stiffness, and the foot pocket offers an optimal fit that's comfortable and snug for minimal drag. For deep sea diving, open sea rescues or recreational spearfishing, these fins are the best option for reliable power. Powerful Kick The stiff blade and multiple grooves force water through the channels for a powerful thrust and maximum propulsion. The blade's curvature and structural ribs provide just enough maneuverability while maintaining strength for a springy kick. An open-foot pocket is designed specifically for wear with dive booties for extra protection and durability. SEALs and Special Ops The IST Rubber Rocket fins are the #1 choice by U.S. military, making them the perfect choice for open-water rescue, salvage divers and more. With optimal mobility and maximum power, you can't get better than these super-strong fins. Rugged Build A tough, sturdy construction offers the perfect balance of strength and flexibility. The premium design stands up to harsh environments and extreme temperatures for unmatched reliability. High-Power Blades Uniquely curved and tapered blades for positive thrust and a powerful kick for more speed with less effort. Dynamic Engineering Deep vents in the blades propel water backward, emulating the acceleration of three synchronized turbo-powered water jets. Hydrodynamic Ribbing Structural ribs add strength and channel water effectively from the toe to the tip of the blade, delivering a spring-like energy return with every stroke. Maximum Agility Long enough to minimize leg fatigue during open-water dive missions, but agile enough to ensure diver maneuverability within confined spaces.
