To use these Eve Taupe Knee High Boots, simply unzip the inner - side zipper, slip your feet in, and zip them up. You can adjust the tie at the thigh to your preferred tightness. They fit true to size, so just pick your regular shoe size. When it comes to maintenance, use a soft brush to gently clean the faux suede surface. Avoid getting them too wet, as it might damage the material. If they get dirty, you can use a mild suede cleaner. Store them in a cool, dry place when not in use to keep their shape. Also, be careful not to scratch the gold detail on the pull string.
