There are many socks on the market with the adjective "aero". But Castelli's Fast Feet socks have undergone development and testing that confirm the validity of such an attribute. The few models that have undergone some testing probably passed the stationary, static test because it's easier. However, the foot is constantly in motion, so we invented a device that mimics 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
