Full Futures F4 Control Series Thruster

These fins are designed specifically for the Futures fin system. If your surfboard has Futures boxes, they will fit perfectly.

The uni-directional carbon fiber layer adds stiffness to the solid fiberglass base. This results in a highly responsive, predictable feel that resists flexing even when you are pushing hard through turns in powerful surf.

While they are built to withstand the rigors of reef breaks, they are excellent for any conditions where you need extra control. If you find your current fins feel too loose or 'whippy' in larger, punchy waves, these will provide the stability you are looking for.

These fins prioritize speed control and stability rather than pure speed generation. They are best suited for surfers who already have speed and need a reliable, stiff fin to hold their line and execute confident maneuvers in demanding conditions.

The combination of solid fiberglass and reinforced carbon fiber makes these significantly more robust than standard glass-on or lightweight composite fins. They are specifically engineered to handle the impact and stress of challenging, high-performance surfing.
