Futures John John Florence Techflex Thruster Fins – Large

The same championship-winning fin, sized up for everyday performance surfing. While John John reaches for the Large Techflex in head-high and under conditions, it's the fin that lets him stay connected through turns and generate speed on performance shortboards with squash tails — the kind of surfing that built his reputation.

Techflex construction delivers a precise balance of stiffness and flex: enough drive to stay fast through flat sections, enough spring to feel alive when you load off the tail. With a neutral template and a Ride Number of 3.4, it sits firmly in speed-control territory — ideal for surfers 75kg+ who want drive and hold without sacrificing responsiveness in playful surf. If you're on a high-performance shortboard and want a fin that rewards committed surfing, this is it.
