Castelli loves taking a good thing and making it better, and the Rosso Corsa, classic standby of the Castelli sock line, are no exception. Designed for performance, the Rosso Corsa Pro 9 socks use different construction on each part of the foot, to optimize cooling, breathability, and comfort. Featuring 200-needle construction for extra stretchability, and asymmetrical design to mirror the shape of your foot, these are Castelli's best performance socks to date.
