v2 f4 5-fin
The F4 5-Fin option combines one of our most popular thruster set ups with our versatile F-4 Quad.  With the V2 foil on the front fins combined with the honeycomb material allow this fin to flex and generate speed, while the thicker tip provides hold through turns. This five-fin option is one of our most versatile choices for small-to-medium sized surfers.

A lightweight hexagonal core gives these fins the feel of glass-ons. Engineered with a medium flex pattern, these are stiffer than Blackstix but more flexible than Fiberglass.
V2 Foil
A V2 Foil is a V. Foil and Flat Foil blend. It takes the best speed generating attributes of the V. (at the base) and transitions into a flat foil in the tip for a controlled release in critical turns. Try the V2 foil if you are transitioning from flat sided fins. The benefits of the V. foil base will be noticeable but the change for your muscle memory will not be too drastic.
