When are shoecovers more than just a splash of style? When they're the Castelli Nano Shoecovers they are. Worn by the Cervelo Test Team, these ultra-lightweight shoecovers are made from Castelli's Nano material, a silicone-coated Lycra that keeps out chilling winds and light rain and road spray as well. Heavy-duty YKK zippers are used at the back for added durability, and silicone-coated elastics are used at the ankles for a snug, form fit for improved aerodynamics and to keep water from running down your leg and straight into your shoes.
The Castelli Nano Shoecovers come in Black and in five sizes from Small through XX-Large.
