Think of the Speede™ as DeFeet's "Cabriolet" (top-down convertible) version of the standard Aireator. Speede™ is the lightweight leader of the DeFeet lineup. Very light, very fast.
Wool is a staple of the DeFeet line. We source the highest grade wools on the planet. Combined with DeFeet construction, the result is the finest wool sock that you can buy.
