Castelli Fast Feet 4 Socks Description:

Constructed with the lightest materials possible, and aerodynamic enough to save watts over the long haul. The Castelli Fast Feet 4 Socks are built for riders looking to maximize speed on hot summer rides. Developed in a wind tunnel and tested by pro athletes looking for fractions of a second when it matters most. The grooves on the upper portion of the sock are intended to disrupt airflow so riders’ legs cut through the wind with minimal output. Finished with hints from the Rossa Corsa Sock for maximum breathability and a next-to-skin fit.
