*Price per pair of fins 

The new SharkII  front, born from the request of K4 athletes who were looking for a fast and more grippy fin for both their Quads and Thrusters. So a fin with a low tip area was designed using the "stiff" material, slimmed down to give more flex and grip in the rear, widening the base to add hold and drive. The result was an exceptional fin with a feeling of speed and precision, and with the right balance between grip and release that brought Alex Mussolini to the podium in Tenerife'18. Also available is the new ' Star Box ' present on some Starboard and Severne models.

A 1Deg option has also been added to the SB version. For those straight boxed board models that want to add some "toe in" for a looser feel

Flex: Super Stiff

The K4 fins are a unique product in the world of windsurfing, they are made using composite polymers with a high degree of engineering with a maximum load of high modulus fibers. The performance of these fins is exceptional in terms of flex, reflex, lightness and resistance to damage. Compared with the classic G10 fins, these fins are lighter and have a superior reflex.

Super Stiff: was developed for an alternative to the original Flex material, which compared to the stiffness of a G10 from a faster reflex and better memory for speed, handling and acceleration making this material is perfect for Wave All-Round.
