Futures Thruster - F4 Thermotech (Small)


The new F series from Futures contains the F2, F4, F6, and F8. These fins are balanced templates that are designed to work for all surfers in all conditions. The solid base directly transfers power, while the tip is still flexible and resilient allowing it to bend and load up. The White Composite (Thermotech) fins have a consistent flex that hold great on the bottom, and then release through turns. If you’re looking for that glass on look, with a higher performance feel than other composites, then you have to try the F series from Futures. The F4 is a small template.

Thermotech fins do not have the traditional plastic feel of a composite fin. Instead they have a consistent flex that creates drive and release through turns. Thermotech fins come with the Futures Truss Base, making them lighter and stronger.

  • HEIGHT - 4.37"
  • BASE - 4.22"
  • AREA - 14.22"
CONSTRUCTION - THERMOTECH: This natural white composite material is constructed from molded-resin with a long-fiberglass matrix. This composite material fuses into a snappy and lightweight fin that retains the proper flex pattern for performance.
FOIL - FLAT: Flat foiled fins break free sooner, and are better at controlling speed. Often surfers prefer them in fast powerful surf where they do not need to create additional speed. If you have muscle memory from riding glass-ons, flat foiled fins will feel the closest.
