Castelli Fast Feet 3 summer cycling socks

The Castelli Fast Feet 3 socks are designed identically to those used by the Soudal-Quick Step team, who demand both comfort and performance, even in hot weather such as during the Tour de France stages in the middle of a heatwave. These lightweight and breathable socks are ideal for summer rides and extreme heat conditions.

The foot section of the socks is inspired by the Castelli Rosso Corsa Socks, providing exceptional comfort inside the shoe. This design ensures a comfortable feel and an excellent fit around your foot and shin.

To prevent the sock from slipping, it features a polyurethane grip band at the top, keeping it perfectly in place even during the most intense efforts, such as races or tough training sessions.

On the shin section, the socks feature a fabric made from Lycra with technical grooves, a technology that improves airflow, thereby offering an aerodynamic advantage.
