Castelli Aero Race Shoe Covers: You can never go too fast. This is a 3-year development project that began at the London TdF prologue and is now in its 4th generation. Good aerodynamics can mean the difference between first and second place, the Castelli design saves 3 watt at 40 km/h. They are cut high for complete coverage and held in place with a silicone gripper. A camlock zip ensures that no loosening occurs during your ride.
