The Long Floating Fins increase leg strength and help athletes swim at faster speeds. With its long, hydrodynamic blade, the Long Floating Fins add propulsion to butterfly and flutter kick. Buoyancy from the fins lifts legs to the surface, reducing drag from the rest of the body. The Long Floating Fins' closed heel design provides protection against hyperflexion of ankles and increases comfort. Great for all ages and levels of swimming, the Long Floating Fins are color-coded by size. Made of soft, floatable rubber the Long Floating Fins will not sink in fresh or salt water, making them ideal for open water and pool training.
