K4 Fins SUP Race Fin

Not only does it sit right at the top on the performance scale, it’s also incredible value for money! RRP is a mere £39.95! We have good stock of both the 21cm and the 24cm.

Here are the details from K4;

45 degree rake so you don’t have to worry about weed or debris.

Foil optimised for paddling speeds, but taking many pointers from our speed windsurfing fins. In fact I (Steve Thorp) stuck this yellow fin in my windsurf and did 48mph on it!
Dynamic Flex material gives more grip, better tracking and more speed than stiffer materials. (Fins with flex are always faster than stiff fins when the loads and AOA are low)
