To use these boots, simply unzip the side zipper and slide your foot in. They're true to size, so you don't have to worry about sizing issues. When walking, the 7 - inch heel and 2 3/4 - inch platform will give you a confident stride. As for maintenance, keep them away from sharp objects to avoid scratching the patent finish. Clean them with a soft, damp cloth regularly. Store them in a cool, dry place, and you can stuff them with tissue paper to help them keep their shape.
