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.
Key features:
- Part of Castelli's Fast Feet project – for riding in warm weather
- Designed to save you watts and keep your feet comfortable while racing
- Aerodynamic leg made from grooved Lycra®
- With polythene grip strip to hold sock firmly in shoe for efficient power transfer
- Feet of socks are shaped to support and cradle your feet
- Weigh 45g as a pair
- Temperature range 10-30°C, 50-86°F
