Engineered to promote short, quick movement through the legs and the feet, LFHYD fins help swimmers to create the natural flow of a flutter kick. With a 100% silicone construction and state-of-the-art comfort fit, the Hydroblade prevents athletes from feeling restricted as they move. In addition to an innovative heel strap design and convenient pull tab, each fin is also created with rounded edges to prevent discomfort in the fin’s foot cavity.
