To use these boots, simply unzip the inner side zipper and step in. Lace up the front for a snug fit and adjust the buckles as you like. When it comes to maintenance, use a soft cloth to wipe off dirt regularly. Avoid getting them wet in heavy rain or submerging them in water. Store them in a cool, dry place when not in use. And remember, since they fit true to size, choose your regular shoe size for the best fit.
