Lightweight, highly windproof with real water resistance, and just the right feature set for easy on-off daily usage, the best shoulder season shoecovers are truly versatile, effective, and allow for real performance in training and racing. Castelli's Perfetto Shoecover's purposeful design, like that of the entire Perfetto line, is focused on this level of performance with exceptional breathability and fit, and a high level of water protection from road spray. This is a do-everything bootie every serious cyclist needs.

The Perfetto design ethos is driven by function, exceptional fabrics and components, and ensuring comfort in any weather,; all while keeping the aesthetics simple and clean. The INFINIUM™ WINDSTOPPER® Stretch Light fabric used 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 has cut the bootie high for extra warmth and finished it with a silicone elastic to keep moisture from entering from the top. This is "the" shoecover for those long cool-weather rides in changing conditions.
