K4 Fins rear SUP surf fins are available in 8, 9, 10, 11, 12 and 13cm in both FCS and Futures (not 8cm).
We’ve had a unanimous thumbs up for the K4 Fins SUP surf fins; from the Bluesmiths team using them in Maui perfection, to the likes of big wave ripper Finn Mullen in Ireland, through to those in the UK having their first experience of Stand Up Paddling with Loco-SUP and of course our k4 team riders.
We’re excited to bring you a substantial range of sizes in the K4 shop to tune your board for every wave. Our rear fins are available in 8, 9, 10, 11, 12 and 13cm in both FCS and Futures (not 8cm).
Sold as singles for £9 each.
Front asymmetric fins are available here:
You can also select large sized rear US or SURF box fins in a choice of Stubby or Flex in the fin shop.
