Make 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.
