To use these sandals, simply adjust the hook - and - loop straps to your desired tightness for a secure and comfortable fit. When you first wear them, take it slow to let your feet get used to the unique support of the cork footbed. For cleaning, use a soft, damp cloth to gently wipe the leather upper. Avoid getting the footbed too wet as it may affect its shape and comfort. Store them in a cool, dry place when not in use. If the footbed loses its softness over time, you can remove it and let it air out for a while.
