The Speedo Biofuse Fitness Fin is an open heel swim fin designed to help swimmers improve their technique, strength & endurance no matter what their level of skill. The fins work comfortably in harmony with the body with a flexible fit & dual density design soft foot pocket & stiff blade, so that swimmers can glide through water with ease. Speedo's Biofuse technology ensures that you will find these swim fins super soft & comfortable to wear. The open heel design means that you can "feel" the water more than an enclosed heel. Features Increase Speed: swimming with fins propels you through the water faster & your legs work harder then they would without fins to maintain the speed. You are able to maintain that quicker pace wearing swim fins, but without fins you would quickly become fatigued. Using swim fins will ultimately make your leg muscles stronger to enable you to swim faster. Improve Leg Strength & Flexibility: Fins will force your feet to extend & flex beyond their normal range of motion, plus the extra force on your ankles as you kick will improve your ankle flexibility. The water resistance fins create, because of the increased surface area of your foot, builds up strength in your legs. Improve Body Position: The buoyancy of fins means that they will help you to keep your legs & overall body position higher in the water. Improve Racing Technique: Swimming with fins means that you can swim at typical race speeds without the fatigue that that brings. You are therefore able to swim as in a race, which means your body movements are faster than they are in typical swim training. Specifications
