Castelli Scorpion Logo 20 Thermal Sock

What Our Gearhead® Experts Are Saying: "I wore these on a run of genuinely cold morning rides, and my ankles never once felt exposed to the wind. The taller cuff sits right where a jacket sleeve tends to gap, and the fit inside my cycling shoe stayed clean the whole ride." Cold has a sneaky way of finding the smallest gap in your kit, and Castelli built the Scorpion Logo 20 Thermal Sock to shut that gap down completely. We love pulling these on before a genuinely frigid start, trusting the tall 20cm cuff to guard the ankle while PrimaLoft yarn works overtime managing moisture and locking in warmth mile after mile.
