For road racing or when you can't use a Fast Feet TT case, these socks save watts.
In the market there are many socks that are sold as aerodynamic. With the Castelli Fast Feet Project, a series of research, developments and tests have been carried out to demonstrate that these socks are really aerodynamic. The tests performed in some socks have been done in static because they are easier. But the foot is always moving, so we have created a design that imitates the movement of the lower leg. We have conducted tests with professional cyclists to corroborate the results. This sock saves 2 watts at 50 km/h.
