The Castelli Fast Feet Sock provides an aero advantage for road racing when it's too warm for the faster shoe covers. Castelli takes the leg portion of their TT shoe-cover and stitch it to their most comfortable sock for in-shoe comfort. It's the same as the aero sock Castelli supply to Team Sky and it's a riders' favourite.
