To use these sandals, simply unzip the back zipper, slide your foot in, and zip it up. They fit true to size, so you don't have to worry about getting the wrong size. When wearing them, be careful as the high heels may require a bit of balance. For maintenance, use a soft cloth to gently clean the clear vinyl part. Avoid using harsh chemicals as they may damage the material. Store them in a cool, dry place when not in use to keep them in good condition.
