SurfCo - Pro Teck Surfboard Power Flex Side Fins for Future in 4", 4.25" and 4.50" (Set of 2 fins)

Power Flex is a Pro Teck Fin with a medium core flex. The fin bends on turns, and then springs back, creating a forward thrust similar to a swim fin. The medium flex core and flexible training edge makes the board turn smooth and fluid with continuous speed. Power Flex Fins are recommended for intermediate to professional surfers.Shortboards4.25" Thruster set for surfers under 150 lbs.4.50" Thurster set for surfer over 140 lbs.Longboards7" Center Fin9" Center Fin4.0" Side FinsPro Teck Fins are surfboard fins with flexible leading and trailing edges designed to enhance board performance and reduce fin cuts. The flexible trailing edge allows the water to flow smoother with less turbulence off the fin. The flexible edge also creates a "rudder action" as the water pressure bends the edge, creating tighter and more fluid turns, similar to the fins of dolphins and sharks. The flexible urethane edge also greatly reduces fin cuts compared to conventional hard edge fins. Center Fin Design The center fins have a streamlined leading and trailing edge that is soft and flexible, making the fin flow smoothly through the water.Side Fin Design The side fins are designed with a "rounded" or "radiused" leading edge that makes turns smoother and forgiving. The trailing edge is designed with an exclusive "beveled" inside edge that allows the water to release off the fin faster and smoother than conventional fins that have a flat or dull trailing edge. Pro Teck Fins are the only fins that have streamlined or "sharp" trailing edges that are soft and flexible, that will greatly reduce fin cuts!
