Futures F4 Alpha Carbon Red Small Thruster Surfboard Fin Set

Premium sustainability, extreme lightness, and all-terrain performance with the F4 Alpha carbon and recycled fishing net template

Experience extraordinary performance with a minimal ecological footprint thanks to the Futures F4 Alpha Carbon Red Small fin set. Meticulously designed for lightweight surfers or young talents (size S: 45 to 60 kg), this set uses award-winning Alpha technology to offer an elastic and predictable response in any type of everyday sea condition.

Sustainably made in California, the Alpha series fins combine recycled NetPlus fishing nets with an air-infused carbon fiber composite. This revolutionary material results in an incredibly lightweight fin—even lighter than traditional honeycomb configurations—with superior structural strength. As part of the iconic F4 (Neutral) template, this set offers a medium flex (Ride Number of 5.5 - Balanced), providing the necessary stability during bottom turns and just enough freedom of movement on the lip of the wave. Its textured matte gray carbon design is topped with powerful fluorescent red graphics.
