For those days when most people ride the trainer, the Castelli Men's Estremo Shoecover uses a fleece-lined GORE-TEX INFINIUM™ WINDSTOPPER® outer layer with a full Polartec® Power Stretch® inner layer to make their warmest bootie ever.
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 they added a second fleece layer with Polartec® Power Stretch® Pro™, which is unrivaled in overall loft. The two layers are thick enough that we had to do a "wheel well" single-layer construction by the ball of the foot to prevent the fabric from rubbing on the crank. They made the bootie high for extra warmth and gave reasonable splash protection.
