4.25" Pro Teck X-FOIL (Stiff Flex)

X-FOIL is a sharper, and thinner extended flexible trailing edge. These fins help you surf smoother, faster, and more fluid while minimizing fin-related injuries. Choose the 4.25" fin if you want a looser board. Stiff flex fins are perfect for the surfer who wants more drive, projection, and drawn out turns.

Note: Available for FCS.
