Fitness Fins are designed to enhance your body’s natural ability in the water. Their dual density design – a stiff blade with a soft, comfortable foot pocket – is tailored to improve your performance and speed during your swim workout. Through increased resistance comes a bigger muscle workload, strengthening your legs and building endurance. Fitness Fins also force ankle extension during kicking, which makes the kick more propulsive and efficient.
