To use these boots, simply unzip the inner side zipper and slide your foot in. They fit true to size, so choose your regular shoe size. When walking, the platform and heel will give you some extra height and stability. For maintenance, keep them away from water and harsh chemicals. You can use a soft cloth to clean the patent leather. If they get scuffed, a little leather polish can help restore their shine. Be careful when walking on slippery surfaces as the high heel may affect your balance.
