Castelli

Estremo Shoe Cover

Winter rides never looked all that enticing before. Frozen toes just aren't your thing, and we don't blame you — but neither is the droning whine of the trainer. Castelli aims to make the blustery outdoors a little bit more appealing, with exceptionally warm kits that keep you toasty from head to toe, and the Estremo Shoe Covers take toasty-foot duty very seriously. They're built to handle extreme temperatures, and extreme conditions, rated for temperatures ranging from 4-degrees to 41-degrees Fahrenheit, and packing in GORETEX Infinium membrane for total protection from rain, snow, sleet, and wheel spray. The cover is built from Polartec Power Stretch Pro, which offers a fleece backed lining to trap heat on the inside, while the outer membrane wards off all showers and wind. A high cuff helps seal any gaps between your kit and your shoes, while an AquaGuard YKK zipper prevents moisture from sneaking in the back.
