To use these sandals, simply unzip the back zipper, slip your foot in, and zip it up. They're great for dressy occasions like parties or nights out. When it comes to maintenance, use a soft, dry cloth to wipe off any dirt or dust. Avoid getting them wet as much as possible. If they do get wet, let them air dry naturally. Make sure to store them in a cool, dry place when not in use to keep them in good condition. And remember, since they fit true to size, there's no need to size up or down.
