To use these sandals, simply unzip the back zipper, slip your foot in, and zip it up. They're great for a night out or a special event. When it comes to maintenance, use a soft cloth to wipe off any dirt or dust. Avoid getting them wet as much as possible, as this could damage the vinyl. And always store them in a cool, dry place. Make sure to check the heel and platform regularly for any signs of wear and tear. If you notice any issues, it's best to get them repaired by a professional.
