Futures Fin School - Main Image
A foil is a cross section of the fin that effects how water flows across it. Airplanes have different wing foils for different performance benefits, and your fins should too. We created different foils for different speeds, conditions, and performance feel.V. and V2 foils feel fluid and drivey, and have the ability to generate speed while flat fins break free sooner and are better at controlling speed.

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.

Validated fin designs will always form our foundation. If you have muscle memory from riding glass-ons, flat foiled fins will feel the closest. Futures has a flat foiled fin line-up in many templates for every size, shape, and style of rider, from finely-tuned smaller templates for Groms and Girls to full-size templates for pro talent like John John Florence, Jordy Smith, Rob Machado, Michel Bourez, Brett Simpson and Ry Craike.

Drive in bottom turns, but breaks free in the lip like a flat fin

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. V. foils feel fluid and drivey, and generate more speed during bottom turns. Try the V2 foil if you are transitioning from flat sided fins, because the benefits of the vector foil base will be noticeable but the change for your muscle memory will not be too drastic.
Great for getting speed if you are having trouble finding it. Fluid rail to rail transitions.

V. Foils are designed to maximize lift with a minimal amount of drag. Fins with this V. Foils will find speed that you did not know was there, or help you get that extra gear to really find drive in your bottom turns. The leading edge of the fin is more rounded accepting more water flow at all angles of attack, and making the fin feel very fluid rail to rail.
Designed for stability at high speeds

Instead of maximizing the lift, this foil is stable with very little drag. The foil is convex on both sides with a small amount of camber or asymmetry.
