To use these boots, simply unzip the side zipper and slide your foot in. Make sure your foot is fully in and then zip it up. These boots are true to size, so pick your regular size. When it comes to maintenance, use a soft cloth to wipe off any dirt or dust after each wear. Avoid wearing them in extremely wet conditions as the patent finish might be affected. Store them in a cool, dry place, standing upright if possible to maintain their shape.
