These ankle boots are super easy to use. Just open the side zipper, slip your feet in, and lace them up to your desired tightness. When it comes to sizing, they fit true to size, so you don't have to worry about getting the wrong size. For maintenance, use a soft cloth to wipe off any dirt or dust regularly. Keep them away from direct sunlight and extreme heat to prevent the faux leather from drying out or cracking. Avoid wearing them in very wet conditions as it might damage the material. With proper care, these boots will serve you well for a long time.
