Castelli FAST FEET 4 socks, Giro pink
Castelli FAST FEET 4 socks
There are many socks on the market with the adjective “aero”. But Castelli Fast Feet 4 socks have undergone research and testing that entitles them to use this attribute. The few competitive socks that passed the tests were likely tested statically, without movement, because it's easier. But the foot and leg are constantly in motion, so we created a device that replicates the movement of the foot and leg. We then verified the results by testing on riders in real-world conditions. At a speed of 50 km/h, these socks save you 2 watts. The latest version has a modified upper cut for more comfort and aerodynamics.|
