Futures Fins F4 Techflex
Pickup currently unavailable
The F4 Techflex fin is one of our most popular models and a longtime favorite of John John’s. The Techflex materials give this fin a responsive flex pattern, optimal for high-performance surfing in powerful waves. The F4 is one of the most balanced fin templates with a thicker tip that provides additional hold on rail.
Small (105lbs - 155lbs) (47kg - 70kg)
Techflex is stiff like Fiberglass but lighter than Honeycomb. The ultimate in flat foiled fins, great for powerful surfers or powerful surf.
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.
