The Castelli Prologo 15" Socks combine the lightweight, snug fit of the Superleggera socks with the durability of the Unlimited socks. They feature a 200-needle construction for a glove-like fit and a Piqué ankle knit for breathability and protection. The design includes a midfoot support band and reinforced heel and toe for comfort during long rides. Additionally, the socks use Q Skin Yarn with antimicrobial silver to enhance breathability and reduce foot odor. Enjoy the best of both worlds with these performance cycling socks.
