Leon Jamaer's signature fins in super stiff "SS" version! Super speed  and loose characteristics give the Leon SS a lot of drive and acceleration.

Straighter outline gives better pivot for pocket riding, more top speed and wider base for drive. They work well for all configurations and in all conditions. Available in two constructions; Dynamic Flex for the classic K4 Loose and grip Feel, or Super Stiff for a direct and responsive style.


I like my signature fins because they are fast, loose and very responsive. Thanks to their outline they have an excellent pivot that allows me to constantly change the direction of the board, adapting my riding to the wave pocket. The relatively wide base gives plenty of drive on bottom turns and projection and grip when pushing off the bottom. They have a very strong release so I can slide the tail into takas whenever I want. I almost only use the Leon 15cm rigid version (rear) and the Shark II 9cm (front) as a quad setup. On normal days I use the fins in the middle of the boxes. If the waves are bigger I put them 4-6mm back. The  Flex version makes browsing a little more controlled and less responsive. It helps to navigate better through the chop and on the wave, from a less powerful release and favors the carve more than the slide. Which Flex to choose also depends on the characteristics you want to give to the board, if you want a more controlled and tolerant sensation ok Flex, for a more reactive and nervous sensation the Stiff version is better.


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.
