US box fins - Stand Up Paddle
The SUP US Box fin fits all boards equipped with a US box. This model is designed for Stand Up Paddle touring and racing, and its large surface area will provide an effective daggerboard that can boost your paddle stroke. It is compatible with our Alpha 11'6, Alpha 12'6×31 and Alpha 12'6×28, Alpha 14′ models. You can also adapt it to a double US rail on our foil boards, such as the Sky Rider or Sroka Air, to enjoy your foilboard in surf and Stand Up Paddle mode. For river, lake, or shallow water enthusiasts, we offer its retractable equivalent on our site, Made in Germany and a Sroka exclusive in France.
For other SUP models, we also offer normal and retractable Slide In fins.
