Why You'll love this fin!

• The 4A is perfect in so many ways. It checks all of the performance boxes. The solid-sized base and width create stability and drive, while the rake and flexible tip enable top-to-bottom turns and maneuverability.
• The Greenough 4A is a bread-and-butter fin. It allows you to feel the shape of a surfboard, it never gets in the way, with it's perfectly neutral design, when sized correctly to the board it fades away and becomes one with your surfing. It holds you tight but lets you loose, and it gives you feedback but disappears- truly the most versatile fin on earth.
• The true beauty of this fin is that you can ride it in any board that has a single fin box. The larger sizes (9"-10.5") are great for single fin longboards, the medium sizes (7.5"- 9") pair well with speed shapes and mid-lengths, and the smaller sizes (6.5"- 8.5") pair well with shortboard single fins and 2+1’s (boards with side fins).
