These KOAK sandals are easy to use. Simply adjust the three straps to your desired tightness for a secure fit. When wearing them, you'll enjoy the comfort of the soft leather and the anatomical footbed. To keep them in good condition, avoid wearing them in very wet conditions as the cork footbed may be damaged. If they get dirty, use a soft, damp cloth to gently clean the leather. Store them in a cool, dry place when not in use to maintain their shape and quality.
