Castelli Estremo Shoecover Black

Castelli set out to create their warmest bootie ever, which meant rethinking how booties are made. For the windproofing they went with GORE-TEX INFINIUM™ WINDSTOPPER® fleece-backed fabric, which also lets more moisture escape than any other windproof fabric. Then Castelli added a second fleece layer with Polartec® Power Stretch® Pro™, which is unrivaled in overall loft. The two layers are thick enough that they had to do a wheel well single-layer construction by the ball of the foot to prevent the fabric from rubbing on the crank. Castelli made the bootie high for extra warmth and give reasonable splash protection.
