CASTELLI FAST FEET 2 SOCKS

For road rides or when it's not possible to wear Fast Feet shoe covers, these socks save you watts.
Numerous models of so-called "aerodynamic socks" are available on the market, but only Castelli Fast Feet have truly been developed and tested to deserve this name. The few socks that have been tested were probably tested under static conditions, without movement, which is simpler. But a foot is always in motion, which is why we have recreated a model capable of replicating the movement of the lower part of the leg. We also conduct tests on test cyclists to verify the results. With these socks, it's possible to save 2 watts at 50 km/h.
