Developed for the 2025 Tour de France and used in World Tour races ever since. Tested in the wind tunnel and on the track, it confirmed what we aimed for: the fastest sock we've ever made. The woven Aero Tech™ fabric reduces drag with its airflow texture and four-way stretch. Instead of an exterior elastic band, an internal silicone stripe keeps everything in place, cutting bulk and seams to a minimum. The single seam sits at the back, out of the airflow. Now available to everyone, not just the pros.
