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. Sizing: Small (Women 6-8); Medium (Men 7-9 / Women 8.5-10.5); Large (Men 9.5-11.5 / Women 11-13); Extra-Large (Men 12+).
