Thermotech Construction Built for Real Surf Performance
The Future Fins FT1 Thermotech Twin Fin Set is engineered for surfers who want more than basic composite fins can deliver. Thermotech fins feel nothing like standard injection-molded plastic fins. The material produces a consistent, predictable flex pattern that builds drive through the bottom turn and releases cleanly at the top, giving twin-fin setups the lively, skatey feel that makes them so effective in punchy and peeling waves.
Every FT1 Thermotech Twin comes mounted on the Futures Truss Base, the proprietary reinforced base design that reduces weight while increasing structural strength at the box interface. The result is a fin that transfers energy efficiently from foot to foil without the dead, stiff feel of a heavier composite.
Made in the USA, the FT1 is a direct product of the engineering discipline Future Fins was founded on. In 1996, the Longo brothers brought their aerospace manufacturing background and hydrogen fuel cell fabrication expertise to surfing, applying the same material science and precision tolerances to fin construction. That foundation shows in the FT1: a fin that surfers can feel working underfoot, not just see in a spec sheet.
Futures Truss Base Technology
The Futures Truss Base is not a cosmetic detail. The truss structure distributes load across the base rather than concentrating stress at a single point, which is why Futures fins consistently outlast standard tab-and-screw designs under hard surfing. The base integrates directly with the Futures fin box system, providing a secure, rattle-free connection every session.
Thermotech Flex Profile
Thermotech is a proprietary composite layup that sits between a fully rigid fiberglass fin and a soft flexible plastic fin in the performance spectrum. The flex is consistent across the foil, meaning the fin bends and returns the same way every turn rather than flexing unpredictably under varying load. For twin setups, this consistency is especially important: both fins need to respond in sync to keep the board tracking and releasing on cue.
Twin Fin Setup Compatibility
The FT1 Thermotech Twin Fin Set is designed for twin-fin surfboards running a Futures fin box system. Twin setups free the tail for flow and speed, and the FT1 foil is shaped to complement that characteristic. The fin drives well through open faces and releases through tighter snaps without the fin washing out.

Frequently Asked Questions
- What is Thermotech and how does it differ from standard composite fins?
- Thermotech is a proprietary composite material used by Future Fins that produces a consistent flex throughout the fin foil. Unlike standard injection-molded plastic fins, Thermotech fins flex and return predictably, generating drive through turns and releasing cleanly at the top rather than feeling stiff or dead underfoot.
- What is the Futures Truss Base?
- The Futures Truss Base is a reinforced base design that distributes load across the fin base rather than concentrating stress at a single point. It makes the fin lighter and stronger than a standard flat base, and it connects securely into the Futures fin box system without rattle or play.
- Are Futures FT1 fins compatible with all surfboard fin boxes?
- The FT1 Thermotech Twin Fin Set is designed specifically for the Futures fin box system. They are not compatible with FCS or other fin box systems without an adapter.
- What type of surfing is the FT1 Thermotech Twin best suited for?
- The FT1 is well suited for twin-fin surfboards in punchy, peeling, or open-face waves where drive, speed, and a loose releasing feel are priorities. The consistent Thermotech flex responds well across a range of surf conditions and surfer styles.
- How many fins come in the FT1 Thermotech Twin Fin Set?
- The set includes two fins, a matched left and right pair for twin-fin surfboard configurations.
- Where are Future Fins FT1 Thermotech fins made?
- Future Fins FT1 Thermotech fins are made in the USA. Future Fins was founded in 1996 by the Longo brothers, who applied their aerospace engineering and precision manufacturing background to surfboard fin production.
- Where can I buy the Future Fins FT1 Thermotech Twin Fin Set?
- The FT1 Thermotech Twin Fin Set is available at Island Water Sports in store and online. Island Water Sports carries a full selection of Future Fins products for South Florida surfers and beyond.
