To use these pumps, simply slip your feet in and adjust the strap if needed. They're great for both formal and semi - formal occasions. When wearing them, be careful on slippery surfaces as the high heels can make you a bit unsteady. For maintenance, keep them in a cool, dry place. Use a soft cloth to clean off any dirt or dust. If there are stains on the satin, you can try using a gentle fabric cleaner, but test it on a small, hidden area first to avoid damage.
