This Futures F4 Thermotech Thruster fin set offers great performance, in a strong construction, at a very reasonable price point.
Not only does this Futures F4 Thruster Fin Set look good, they are relatively cheap, and they offer you buckets of surfing performance.
Constructed using Futures Thermotech process, these 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.
Well worth having a pair at this price, even if its just for a spare.
