Castelli Cervelo Test Team Aero Race Overshoes 2009

Castelli Cervelo Test Team Aero Race Overshoes 2009: With your bike and wheels being so aerodynamic, the air hitting your feetand lower legs is very "clean" and therefore a lot of drag is generated in this area. So we engineered these booties to smooth the airflow over the shoe and around the front of the leg, then to smoothly separate from the leg with the structured "golf ball dimple" fabric. The gripper elastic is designed to hold the top line firm just below the calf muscle. Besides being an obvious advantage in the time trials, you get the aero advantage on the road too.
