Designed for serious cyclists, time trialists, and racers who demand the absolute best, these socks are the result of Castelli´s relentless pursuit of aerodynamic perfection through its dedicated Fast Feet project. More than just a sock, the Fast Feet 4 is a piece of high-performance equipment, meticulously engineered to slice through the air and save precious watts when every second counts.

They represent the pinnacle of cycling sock innovation, offering a seamless integration of speed and function, ensuring your feet are not only comfortable but also faster than ever before.Bullet Points.* Castelli´s Fast Feet project — for maximum aerodynamics* Foot portion based on Castelli Rosso Corsa Sock for in-shoe comfort* Polyurethane grip strip at top to keep sock in place* Leg portion constructed with engineered grooved Lycra® to help detach airflow.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.Technical Specifications.* Gender: Men, Women* Fabric Type: Synthetic* Discipline: Road, Time Trial, Racing* Key Technology: Engineered grooved Lycra®, Rosso Corsa footbed* Cuff Height: Tall aero profile* Feature: Polyurethane top gripper for secure placement* Primary Benefit: Proven 2-watt saving at 50 km/h
