Full Futures K2 Alpha Keel

These fins are specifically designed for twin-fin setups. They excel on retro-style fish shapes or modern twin-fin boards that prioritize flow, speed, and a loose, skatey feel.

The Alpha construction, which blends recycled fishing nets with carbon, creates a fin that is lightweight and stiff. You get the drive and responsiveness of carbon-infused materials, but with a slightly more dampened, forgiving flex pattern than traditional solid fiberglass.

Not at all. The truss design is engineered to reduce weight while maintaining structural integrity. It provides the stability you need for high-speed turns without making the fin feel rigid or unresponsive.

Yes, they are excellent in smaller conditions. The classic keel template provides plenty of surface area to generate speed and drive through flat sections where you might otherwise bog down.

The 4-degree cant angle provides a balance between speed and hold. It helps the board feel responsive when initiating turns while ensuring you maintain enough grip on the rail during drawn-out carves.
