In frigid climates, shoe covers are a winter weather necessity. Castelli has perfected the on the bike fit of its shoe covers for comfort, fit, and weather protection. The Castelli Diluvio All Road Shoe Covers are its first overshoe designed specifically for riders who need to walk short distances in them. Castelli constructed the Diluvio All Road shoe covers from the same neoprene as its more on the bike focused version. Neoprene is an ideal insulation to keep your feet warm and dry. The conforming fit of these covers has also been coupled with a full length, waterproof rear zipper, which eliminates water infiltration while making the covers easier to enter and exit. Additionally, Castelli added a zipper garage, a 16cm fitted cuff, and an O ring at the top of the opening in order to seal out water. It's also worth noting that, even though these were designed to be as waterproof as possible, in order to provide a slip free walking surface, the soles of the All Road are open. You may not stay quite as dry as with the standard Diluvio, but you won't wear out the covers while walking to the office, into the grocery store, or up flights of stairs. In low light conditions you'll also appreciate the wide reflective tape sewn around the zipper and the large Castelli logo on the sides. The Castelli Diluvio All Road Shoe Covers are available in the color Black and in the sizes SmallMedium 39 42, LargeX Large 43 46, and XX Large47 48.
