Power Flex 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.
Thruster, quads and side fins available for FCS and Future fin systems.

Pro Teck fins were developed after our son received a severe fin cut to his inner thigh that required over (200) stitches. As my wife and I watched the surgeon work on our son, I vowed to develop surfboard fins that would keep others from such a traumatic experience. We hope you are pleased with the Pro Teck fins and all the SurfCo products.
