To use these booties, simply put them on like you would with any regular shoes. They're great for casual outings, parties, or even a day at work. When it comes to sizing, they fit true to size, so you can order your normal shoe size. For maintenance, use a soft brush to clean off dirt from the faux suede surface. Avoid getting them too wet as it may damage the material. Store them in a cool, dry place when not in use to keep them in good condition.
