Duotone Crush SLS Foil Board 2026

The 2026 Duotone Crush SLS is built for riders chasing the perfect balance of reactivity, connection, and efficiency on every wave. Designed with feedback from Duotone’s top prone foil athletes, the Crush SLS blends cutting-edge carbon construction with refined shaping to deliver the most direct feel possible between board, foil, and rider.

A revised outline and volume distribution minimize swing weight for instant rail-to-rail response, letting you carve tighter lines and link sections with precision. The low rocker profile makes pumping between waves smooth and efficient, while a thin, low-volume deck brings you closer to the foil for unmatched feedback and control.

Soft, rounded rails make the Crush forgiving on touchdowns and comfortable to handle when duck diving, while the tail cut-outs enhance water release and help initiate early take-offs. A subtle nose rocker ensures smooth lift-offs and prevents nose dives during steep drops.

Every detail has been fine-tuned for performance. The Crush SLS omits footstrap inserts to reduce weight and improve sensitivity, while lightweight carbon tracks and a thin EVA footpad transmit every movement directly to your foil. The full Biax Carbon PVC sandwich construction combines stiffness, strength, and responsiveness in a featherlight build that withstands heavy use without compromise.

Available in 4’2” x 17.5” (27L) and 4’5” x 18.5” (35L), the 4’2” model delivers ultimate agility for expert prone foilers seeking tight turns and high responsiveness, while the 4’5” offers extra volume and stability—perfect for heavier riders or those progressing in prone foiling.
