About this product
The Castelli Fast Feet 4 Cycling Socks is stocked by 1 shop we compare on Shopperazzi. Listed prices start at £28.00.
The few socks that have been tested have probably been tested with a static, nonmoving test because it's easier. But a foot is always in motion, so they created a jig that replicates the movement of the lower leg. And they tested it on actual riders to verify the results. This sock can save 2 watts at 50 km/h. The newest version has an updated cuff fit for more comfort and aerodynamic gains.
