K4 Futures Thruster Fin Set (x3) for Surfboard Paddleboard SUP

“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.

We’re excited to bring you a substantial range of sizes in the K4 shop to tune your board for every wave.
