Take your swimming to the next level with the Speedo Biofuse Fitness Fin. Made from 100% silicone for excellent comfort, these fins feature stiff blades that provide maximum water resistance and a more challenging lower body workout. They promote better ankle mobility and provide extra propulsion to your stroke, allowing you to focus on your body positioning or kick technique. The added resistance also helps to strengthen your leg muscles, improve your workout speed, and increase your ankle mobility.
