You'll barely notice Castelli's Superleggera 12 Sock in your cycling shoe, with the exception of cooler, airier comfort. It's mostly made of mesh to ensure sufficient ventilation, and the ankle is especially stretchy to ensure full pedal-friendly comfort. Castelli made it out of Meryl Skinlife yarns for ultralight thermal regulation suitable for warmer weather. There's a support band around the midfoot to ensure a snug fit.
