Overview Description. There are lots of so-called aero socks out there. But the Castelli Fast Feet 4 Sock has the development and testing to back up the claim. While many competitors´ products may be tested in static, nonmoving conditions for simplicity, Castelli understands that a cyclist´s foot is always in motion. To achieve real-world results, we created a specialized jig that accurately replicates the pedaling movement of the lower leg. We then tested the socks extensively on actual riders to verify the data. The result is a sock that can save a proven 2 watts at 50 km/h. This newest version of the Fast Feet 4 features an updated cuff fit, enhancing both long-distance comfort and aerodynamic gains, ensuring it stays perfectly in place without constriction. The foot portion is derived from our celebrated Rosso Corsa sock, guaranteeing exceptional in-shoe comfort and moisture management, while the leg portion is all about pure speed. Product Care. To maintain the elite performance characteristics of your Fast Feet 4 Sock, please follow standard care instructions for technical cycling apparel. The Castelli Fast Feet sock has the development and testing to back up the aerodynamic claims, and proper care will preserve these qualities for every ride and race. We recommend washing in cool water and air drying to ensure longevity.
