The K4 original fin for performance wave riding. Lots of flex for amazing grip and looseness on the wave. Raked template for control. A progressive foil for different flows between tip and base. Test winner.
Will loosen up a 'stiff' board and are particularly sweet as twin fins as they eliminate that unwanted top turn spin out.
Sizes 12-17cm US SLOT heads.
