True Ames Alex Lopez Futures Diamond Twin Surfboard Fins - ClearWe couldn't be more stoked to link up with the ultra talented surfer shaper Alex Lopez to make fins. We are kicking things off with his favorite twin template dubbed the Diamond Twin. This template sits at the lower limits of the hybrid twin category with a 5. 35 base and 5. 25 depth. You can anticipate plenty of drive out of these fins, while the narrowing tip and eye catching rake will provide the needed sensitivity for quick directional changes.
