Because the fin is angled below the body, during the kick phase, the body is pushed forward and down, instead of straight ahead.  With the SF-15 fin, that 27° angle has been designed into the fin.  This means that 100% of the energy expended during the kick phase is directed toward the propulsion of the diver.  To achieve maximum performance from this fin, use a small bent-knee kick with a light rhythm. This creates less strain on the leg muscles compared with traditional fins, reducing the diver's fatigue and subsequent air consumption.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3\u003e\u003cspan\u003eFeatures:\u003c\/span\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan\u003eThree material design for increased performance compared to standard split fins\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003ePatented 27° Angled Blade Design\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eEnhanced propeller-fin technology optimizes efficiency\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eMulti-compound foot pocket increases power transfer to the fin blade\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eReinforced side-rails decrease blade separation increasing stability and kick-style versatility\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eOptimized blade scoops increase water channeling\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eInnovative hydrofoil design that produces forward motion (propulsion) with less effort\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003e10% longer blade than SF-8 for enhanced propeller effect\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e\u003cspan\u003eTechnology:\u003c\/span\u003e\u003c\/h3\u003e\n\u003ch5\u003eANGLED BLADE DESIGN (A.B.D.)\u003c\/h5\u003e\n\u003cdiv\u003eThe Angled Blade Design accommodates for this anatomical characteristic and ensures maximum efficiency throughout the kicking cycle\u003c\/div\u003e\n\u003cdiv\u003e\u003c\/div\u003e\n\u003cdiv\u003e\n\u003ch5\u003eEZ STRAP AND BUCKLE SYSTEM\u003c\/h5\u003e\n\u003cdiv\u003eTUSA’s EZ strap and Buckle System allows fins to be quickly and easily adjusted with minimal effort.
