True Ames | Georgo Greenough A4 | 7.0" | Green (Used)

$45.00

The Greenough 4-A is not only the bread and butter of our collection, but it’s also been the most popular single fin worldwide for decades–and for good reason–its incredible functionality and versatility means it’ll work on just about anything.

The man behind this revolutionary fin is George Greenough, whom the surf world is forever indebted to for his wave-riding performance innovations beginning in the '60s. Greenough ultimately paved the way from traditional logging to more progressive surfing in the pocket through the development of his Velo-Spoon kneeboard designs. To complement his kneeboards, Greenough found inspiration from mother nature for his fin templates through studying the tail fins of tuna–one of the fastest and most maneuverable fish in the ocean. The subsequent high-aspect ratio design he created allowed surfers to place themselves in more critical parts of the wave and execute more radical turns; it truly ushered in a new era of high performance capability.
