To use these sandals, simply unzip the back zipper and slide your foot in. They are designed to fit true to size, so you don't have to worry about sizing issues. When wearing them, be careful on slippery surfaces due to the high heel and platform. To maintain these sandals, clean them with a soft, damp cloth to keep the clear vinyl looking shiny. Avoid using harsh chemicals that could damage the material. Store them in a cool, dry place when not in use to prevent any warping or damage.
