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.
The Flex have more ‘flex!’ and give a looser ride with more grip. The Stubbies provide a more direct drivey feeling with easier release for getting the tail to slide. Our ‘go to’ set up for beginners would be a 16 or 18cm rear with 12cm sides. Experts I’m sure will relish our selection of US rear sizes to set up the feel of their board perfectly.
Rear fcs/futures symmetrical fins will be available shortly.
