Our 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 13-18cm US SLOT heads.
K4 Flex (Rear) PAIR
To keep your K4fins looking clean and shiny it does them no harm at all to go in the dish washer every now and then. This is highly recommended.
Minor nicks and scrapes can be easily sanded out with 240 or 400 wet and dry.
Major damage can be trimmed or scraped smooth with a sharp knife.
