To use these sandals, simply open the hook and slide your feet in. They're great for everyday wear, whether you're going out for a stroll or a romantic dinner. When it comes to maintenance, use a soft, damp cloth to clean the leather upper and inner lining. Avoid getting the synthetic sole wet for long periods as it may affect its durability. Store them in a cool, dry place when not in use to keep them in good condition. If the hook gets loose over time, you can easily tighten it with a small tool. Enjoy your new, comfortable sandals!
