The Futures EA Blackstix Medium is a high-performance thruster fin set designed by legendary Hawaiian shaper Eric Arakawa. Engineered specifically for speed generation in smaller, softer, or mushier wave conditions, these fins maximize your board's liveliness when the ocean lacks power. • Template Category: Rake (Drawn-out, control, and drive).
