castelli fast feet 2 socks in white

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. Theyâre therefore extremely comfortable to wear.Features:Part of Castelli's fast feet project for riding in warm weatherDesigned to save you watts and keep your feet comfortable while racingAerodynamic leg made from grooved lycraWith polythene grip strip to hold sock firmly in shoe for efficient power transferFeet of socks are shaped to support and cradle your feetWeigh 45g as a pairTemperature range 10-30c, 50-86f
