K4 Fins Flexy Rear Fins in Slot and US Box – Flex: HIGH – Test winner.

Our original fin for performance wave riding and the first choice for pro team riders whether twin, quad or thruster. Great flex for amazing grip and looseness on the wave. Raked template for control. A progressive foil for different flows between tip and base.  Will loosen up a ‘stiff’ board and are particularly sweet as twin fins as they eliminate that unwanted top turn spin out.


Sold as singles for £24.50 each. —– FREE UK DELIVERY ON THIS ITEM
