There are many socks with the attribute "aero" on the market. But Fast Feet socks from CASTELLI have undergone development and testing that confirm the validity of such an attribute. The few models that have had some testing have probably gone through the non-moving, static test because that's easier. However, the foot is constantly in motion, so we invented a device that imitates the movement of the leg and foot. We verify the results by testing on riders. These socks can save you 2 watts at a speed of 50 km/h. The latest version has an improved cuff for more comfort and aerodynamics
