K4 FCS Surf Assy Side Front Fin Pair

These fins are Asymmetrical.

“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. Our asymmetric front fins are available in 8, 10, 12, 13  and 14cm.” – K4 Fins

These K4 surfboard FCS fins are perfect for directional kiteboard surfboards, normal surfboards and wave sups. Buy the 10cm ones for a looser feel or for smaller boards and buy the 12cm for pretty much everything else.
