Castelli Sock Fast Feet Black

Castelli's Fast Feet project offers aerodynamic foot coverings for all conditions. These Fast Feet Socks give you an aero edge in road racing when it's too hot for shoecovers. We've combined the leg part of our TT shoecover with our most comfortable sock for great in - shoe comfort. Just like the aero socks we provide to Team Sky, they're a favorite among riders. You can also customize them through our Servizio Corse program.

How to use: Simply put on the socks like you would with any regular socks before your road race. They're designed to fit comfortably in your shoes. Note: These socks are best for road racing when it's warm. Don't try to use them in extremely cold conditions as they're not made for that. Maintenance: Wash them in cold water after each use to keep them in good shape. You can air - dry them, and avoid using high - heat dryers as it may damage the fabric.
