Speedo Biofuse Training Fin

Designed to improve your lower body's fitness, enhancing your speed in the water.

Swimming fitness fins are designed to enhance you body's natural ability in the water. The dual-density design of the Biofuse Training Fin uses a stiff blade with a soft, comfortable foot pocket which is tailored to improve performance and speed during your swim workout. Although there is increased resistance which comes from bigger muscle workload, this strengthens your legs as well as builds endurance allowing you to go further for longer. These training fins also force ankle extension during kicking which makes your kicks more propulsive and efficient improving your technique further.
