With more of a traditional look, the Classico is a perennial favorite for riders who like a taller, rib cuff and favor wool fibers. The thin foot fits in the closest fitting cycling shoes. The wool fibers result in a slightly higher volume (thicker) fit than the Aireator. DeFeet crafts all of its wool socks with the highest grade wools that are grown, washed and dyed entirely in the United States. This fact makes the Classico even more unique among wool socks and much more sustainably made than most others that ship their wool thousands of miles before making it onto your feet.
