If you live in a region similar to ours, you know that winter saddle time can be a painful affair. And if you think that you're going to get in those base miles without covering up your soon to be frozen feet, you're sorely mistaken. We rely on the Castelli Ultra Shoecover to keep our toes connected to our feet in the bowels of winter's gloom. Using patented fabric that blocks winter's harshest elements, the Ultra Shoecover is a staple for anyone that it isn't satisfied with only riding four months out of a year.While some fabrics claim to be windproof, no one produces a more rigorously tested fabric than W.L. Gore. That's why Castelli's Ultra Shoecover is made from Gore's patented WindStopper X-Fast 2 material. This microfleece fabric not only warms and repels water, but as its name suggests, it completely stops the wind's chilling effects. To further ensure that no cold or water infiltrates the cover, the Ultra Shoecover uses an anatomic design with a high cuff and waterproof rear zipper. Castelli also included reflective detailing throughout the cover for safer riding in low-light conditions.The Castelli Ultra Shoecover is available in sizes from Small to XX-Large, and in the color Black.
