Castelli Fast Feet 2 Socks

Fast by name and nature, these socks use grooved Lycra at the leg to detach the airflow as you ride, thus saving watts. Meanwhile, polyurethane grip strips anchor your feet, ensuring the full power of your legs reaches the pedals.

The feet of these smart, clean-looking socks are modelled on the Rosso Corsa Socks, which are constructed asymmetrically, with left and right-specific foot shapes, and knitted to give the right level of cushioning, stretch and compression at every part of the foot. They're therefore extremely comfortable to wear.
