To use these sandals, simply adjust the hook-and-loop straps on the top and the strap around the heel to get the most comfortable fit for your feet. When you're done wearing them, you can remove the footbed to air them out and keep them fresh. For maintenance, use a soft, damp cloth to wipe the leather upper regularly. Avoid exposing them to extreme heat or moisture. If the footbed gets dirty, you can gently clean it with mild soap and water, then let it dry thoroughly before putting it back in the sandals.
