To wear these slides, simply slip your feet in. They're easy to put on and take off. When it comes to sizing, just go with your regular shoe size as they fit true to size. For maintenance, use a soft, dry cloth to wipe off any dirt or dust. Avoid exposing them to extreme heat or moisture. If they get wet, let them air - dry naturally. Don't use harsh chemicals or abrasive cleaners on them to keep the clear vinyl looking great.
