Biofuse Fitness fins are short, dual intensity fins with stiff blades, developed to create maximum resistance in the water. Added resistance increases the workload on your leg muscles which in-turn increases strength and endurance. Fitness Fins add extra propulsion to the stroke, which increases speed with minimum effort, leaving you free to ingrain correct technique. The increased surface created by the Fitness Fins forces ankle extension during kicking, which makes the kick more propulsive and efficient.
