These are Japanese-made, high-quality pure rubber split fins that work great if you have any of these problems: 1. Dislike expending lots of energy to move underwater; 2. Cannot expend lots of energy to move underwater; 3. Have weak leg, calf, or foot strength; and/or 4. Have "floaty" feet with difficulty maintaining good buoyancy. These are the "gold standard" of split fins--the legendary flagship split-fin, perfected. The Bio-Fin Pro has effortless propulsion and turn-key comfort that ends leg strain and joint fatigue. Apollo supplies militaries worldwide with this identical fin. Key benefits: ✓Propeller-effect split blade for effortless thrust; ✓Up to 40% less leg fatigue & air consumption; ✓Quick-release fin straps provide easy removal from feet; and ✓100% natural rubber — built in Tokyo, Japan. Unlike stiff plastic or synthetic fins that rely on force, the Bio-Fin works on the principles of propeller aerodynamics. On every kick, the natural flexibility of the rubber lets the split blade twist and form a pair of wings. That opens the slit smoothly and with just the right force, creating a low-drag, high-thrust jet of water that drives you forward on a fraction of the effort. The blade is molded from Apollo’s original, highly tuned natural-rubber formulation — a fluid, dynamic flex that synthetic materials simply cannot replicate, for maximum energy transfer on every stroke. Natural rubber also resists decline, so the blade keeps its snap and efficiency over years of diving. Because natural rubber absorbs the shock of the kick cycle while providing an incredible elastic snap, the Bio-Fin Pro SP drastically reduces stress on the ankles, knees, and hips. Independent testing has shown it can reduce muscle fatigue and air consumption by up to 40% — so you stay down longer, swim farther, and surface feeling refreshed.
