The standard and pinnacle of asymmetrical surfboard fin designs Precision, fluidity, and all-around performance with solid rail-to-rail engagement Solid fiberglass construction, raw finish Toe-side Twin - 5° cant, flat inside foil Heel-side front - 6° cant, flat inside foil / Heel-side rear - 3° cant, flat inside foil The Ryan Burch Asym set should arguably be the go-to asym set on the planet earth. No one has messed with, tested, and dialed in the asym concept more than Ryan Burch. The toe side fin is from the Burch Twin. The heel side fins are Ryan's unique paddle concept - inspired by George Greenough's paddle fins and further influenced by Daniel "Tomo" Thompson's fin experimentation. The heel side fins have a stubby outline, but the cutaway trailing edge opens up the fin in transition and on rail. The compatibility of these three fins is unmatched. A frontside bottom turn will feel drivey, quick, and full of power - and the heel side will feel responsive, buttery, smooth, and loose. The name of the game here is keeping each rail engaged and each transition harmoniously balanced.

The frontside will feel drivey, quick, and full of power, while the heel side will feel responsive, buttery, smooth, and loose.
This is the set for a regular-footer on a dedicated asymmetrical board who wants the frontside powerful and the backside free — it shines on punchy beachbreak and steeper walls where forehand and backhand demand different things. Goofy-footers need the Goofy version, and on a standard symmetrical twin or fish you should run the Burch Twin instead.
The Ryan Burch Asymmetrical Regular is a 1+2 asymmetrical fin set for regular-foot asymmetrical boards, made by True Ames in solid fiberglass with Futures-compatible bases. The toe-side fin is taken from the Burch Twin template, while the heel-side fins use Burch's paddle concept, inspired by Greenough's paddle fins and Tomo's fin experimentation, with a stubby outline and cutaway trailing edge. A mirrored Goofy version exists for goofy-foot riders.
