To wear these sandals, simply unzip the back zipper, slip your foot in, and zip it up. They're true to size, so pick your regular shoe size. When walking, be careful on uneven surfaces because of the high heel. To keep them looking great, clean the vinyl with a soft, damp cloth and avoid getting the rhinestones wet too much. Store them in a cool, dry place away from direct sunlight to prevent the vinyl from fading.
