Get the most out of every pedal stroke with cycling socks that have proven to add speed to your ride! The Castelli Fast Feet 4 socks are not just another aero model; they are an engineering masterpiece and have undergone extensive testing to become perfect for moving feet. So, save precious watts and leave the competition behind with this ultimate race accessory!
Composition and fit
The Fast Feet 4 cycling sock is composed of two parts to ensure both speed and comfort. The foot section is based on Castelli's famous Rosso Corsa sock, ensuring a soft fit and excellent moisture management inside the shoe. The leg section is made of specially developed grooved Lycra, which helps to detach airflow for minimal drag. This race-fit sock performs optimally in a wide temperature range from 10°C to 38°C, with the breathability of the footbed keeping your feet fresh during maximum exertion.
Smart extras and high-quality finish
Castelli has fitted this fourth generation with an updated cuff that fits more closely for aerodynamic gains without sacrificing comfort. On the inside of the top edge is a polyurethane grip strip that keeps the sock securely in place, even during explosive demarrages. While the socks are super lightweight (48 grams), the aerodynamic construction will save you 2 watts at a speed of 50 km/h. With a seamless transition between the different fabrics, and the refined finish, the Fast Feet 4 are the most sophisticated aero socks on the market for time trialists and road cyclists.
