What Our Gearhead® Experts Are Saying: "These socks are super comfortable and stay locked in place, even on long climbs. The Q Skin yarns actually help with odor on multi-day trips, and the 18cm cuff hits that perfect modern height. I wear these on everything from race days to recovery spins." Some gear gets overlooked—until it makes a difference. The Castelli Giro d'Italia Sock 18 brings the kind of subtle performance that keeps our feet fresh, dry, and supported no matter how long the ride. Made with Q Skin yarns, these socks actively reduce odor while managing moisture during intense efforts or hot weather slogs. The 18cm cuff provides modern coverage, and a breathable mesh upper keeps air flowing when the tempo kicks up. A compression cuff holds everything in place without pinching, and extra cushioning underfoot adds comfort on big mileage days. Finished with arch support for a secure feel, these socks are built for all-day rides—and worthy of the Giro name.
