To keep our feet warm during the cold months of outdoor riding we slip the Castelli Espresso Shoecover over our shoes and hit the road. The GORE-TEX INFINIUM WINDSTOPPER fabric is designed to keep in heat while letting moisture escape shedding light rain and road spray as we go. The neoprene panel at the back stretches to provide the perfect fit as the full-length zipper and reflective tabs ease our entry and exit so we can be on our way.
