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.

K4 Flex US Box Rear Fin for SUP, Paddleboard or Windsurf Board
K4 Flexy US Box Rear Fin for SUP / Paddleboard or Windsurf Board
These can be used as 'twinsers' or as a single rear fin. They come complete with nylon plate and screw for US box fin systems.
"Our original fin for performance wave riding. Lots of flex for amazing grip and looseness on the wave. Raked template for control. A progressive foil for different flows between tip and base. Test winner. Will loosen up a 'stiff' board and are particularly sweet as twin fins as they eliminate that unwanted top turn spin out." - K4 Fins
