Speedo Biofuse Training Fin
- 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.
