Description

Castelli Fast Feet project: aerodynamic overshoes for all conditions. The Fast Feet sock provides an aerodynamic advantage for road racing when its too hot for faster overshoes. Weve taken the leg portion of our time trial overshoe and applied it to our most comfortable sock to ensure maximum comfort. Its the same streamlined sock we supply to the Quickstep Grenadiers and is a firm favorite with runners.
