Abstract: An improved dielectric overshoe is disclosed in which upper portions are formed of a first rubber composition having good dielectric characteristics and lower portions and a sole are formed of a second rubber composition that has good dielectric characteristic, but has slightly better wear characteristics than the first rubber composition. The shoe has a high arch to provide room for the mounting of a climbing cleat. Buckles seal the tongue of the shoe, with an uppermost one of the buckles being spaced from an opening for receiving a wearer's foot by a distance great enough to provide room for mounting of a strap to secure a climbing cleat to the overshoe. A reinforcement lip is placed around the entire opening, and in combination with the buckles and the tongue provides a nearly water-tight seal between the overshoe and the wearer's ankle preventing seepage of any water into the overshoe opening.
