To wear these sandals, start by adjusting the front lace - up to your preferred tightness. The interchangeable laces allow you to change the look easily. When putting them on, make sure your foot is centered on the platform. As for maintenance, use a soft cloth to clean the black patent leather regularly. Avoid wearing them in very wet conditions to prevent damage to the material. Store them in a cool, dry place when not in use. And remember, they are true to size, so you don't have to worry about sizing issues.
