To use these sandals, simply unzip the back, slip your foot in, and zip it up. They are designed to fit true to size, so pick your regular shoe size. When wearing them, be careful on slippery surfaces as the high heel can make it a bit tricky to balance. To keep them looking great, wipe them with a soft, dry cloth after each use. Avoid getting them wet, as water can damage the satin material. Store them in a cool, dry place, away from direct sunlight.
