The present invention is a weather-resistant cover for a walking brace, cast, and/or orthotic device used on a human leg and foot. This innovative cover includes a sturdy, slip-resistant outer sole for safe mobility. The majority of the protective cover is comprised of a flexible, resilient, and weather-resistant material. In contrast, patches of flexible, thin fabric are present over the regulatory buttons of the walking brace, cast, and/or orthotic device. These patches allow for the fitting of the walking brace, cast, or orthotic device to be adjusted while the cover is in use. A drawstring is present at the top of the cover to ensure the cover is completely weather-resistant. This cover also includes a longitudinal fastener at the rear of the cover to allow the wearer to easily place their leg/foot in the device. This fastener, when closed, secures the wearer's appendage in the cover.
