Power Flex is a Pro Teck Fin with a medium core flex. The fin bends on turns, and then springs back, creating forward thrust similar to a swim fin. The medium flex core and flexible trailing edge makes the board turn smooth and fluid, with continuous speed.
This quad set includes two (2) 4.50" side fins and two (2) 4" trailer fins.
Power Flex Fins are recommended for intermediate to professional surfers.
