Castelli's Superleggera 12 Sock features a minimalist design and performance-oriented features for cyclists who are serious about riding and racing. An ultralight diaphanous mesh ankle keeps us cool when the mercury rises, and a midfoot support band is compressive and comforting. We'll be riding with the Superleggera 12 Socks all day and still feel on top of the world by the end of our ride.
