K4 have been circulating prototype SUP fins for quite a while now, leaked out to various SUP rippers around the globe to test and shred with. They’ve delayed launching them until they had extensive SUP time under our belts and they are now better able to advise on size and performance characteristics.
There has been a unanimous thumbs up; from the Bluesmiths team using them in Maui perfection, to the likes of big wave ripper Finn Mullen in Ireland, through to Loco SUP leading the charge in the UK & Europe with their growing team of riders.
We’re pretty stoked to bring you a substantial range of sizes straight off the bat. Our front fins are available in 8, 10, 12 and 14cm (fcs/futures) and our rear US box in a choice of Stubby (12,14,16,18cm) or Flex (14,15,16,17cm).
Rear fcs/futures symmetrical fins will be available shortly.
