Futures SB1 Thermotech Sidebite Fins

Thermotech construction provides a more consistent flex pattern than standard composite or plastic fins. This allows for a smoother, more predictable feel through turns, offering better drive and release without the stiff, dead sensation often found in cheaper molded options.

These fins are designed specifically for longboards and stand-up paddleboards that utilize a 2+1 fin configuration. As long as your board uses the Futures fin system, these will be a direct, compatible fit.

A neutral template is designed to be versatile and balanced, meaning it doesn't lean too heavily toward either extreme speed or extreme hold. It is a reliable, all-around choice that performs consistently in a wide variety of wave conditions.

The truss base design removes unnecessary material to reduce the overall weight of the fin while maintaining structural integrity. This keeps the fin lightweight without sacrificing the strength needed to hold your line on the wave face.

The 4-degree cant angle helps provide a bit more drive and responsiveness when you are turning. It essentially tilts the fins slightly outward, which helps generate speed and hold during rail-to-rail transitions.
