The energy you load up on a carbon fiber fin comes back in a burst of energy. Combine that with texalium for even more spring out of your turns.
RIDE NUMBER
foil
FLAT Foil
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.
