Description: The Castelli Perfetto Shoe Cover design ethos is driven by function, exceptional fabrics and components, and ensuring comfort in any weather while keeping the aesthetics simple and clean. The fabric here is the key, providing enough stretch for a perfect fit and easy on/off, combined with best-in-class breathability to let moisture escape, while being fully windproof and splash resistant. The oversized YKK® zipper on the back is easy to open and close. Castelli cut the bootie high for extra warmth and finished it with silicone elastic to keep moisture from entering from the top. This is the shoe cover for those long cool-weather rides in changing conditions. The Perfetto Shoecover's purposeful design, like that of the entire Perfetto line, including the Gabba, is focused on performance with exceptional breathability and fit, with a high level of water protection from road spray. The do-everything bootie!
