Castelli Fast Feet 2 Socks

The Fast Socks are designed to enhance your cycling performance, featuring grooved Lycra® at the leg that detaches the airflow to save valuable watts as you ride. Additionally, the socks have polyurethane grip strips that anchor your feet, allowing you to apply full power to the pedals.

The feet of these socks are based on the Rosso Corsa Socks, which are constructed asymmetrically, with left and right-specific foot shapes. This design ensures that the socks fit your feet comfortably, while the knitted material offers cushioning, stretch, and compression at every part of your foot.
