BootcapMake any pair of boots warmer with the simplicity of the Bootcap. While most boots rely on a hard plastic shell around the toes to keep them warm, the Bootcap goes over the toe box, using closed cell EVA foam to keep heat from escaping the boot and thus keep feet warmer, longer. It's easy to install, with adhesive strips to prevent overlap and buckling, has a tapered bottom edge for an integrated fit, and is available in a handful of colors.
