Pro Teck Powerflex Side Fins Futures 4.0" By Surfco Hawaii

1 set of 4.00" Futures compatible PowerFlex Side 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.
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!
Power Flex Fins are recommended for intermediate to professional surfers.
