To use these Ziera Hastice women's sandals, simply adjust the buckles to fit your feet comfortably. They're great for everyday wear, whether you're running errands or going out for a stroll. When it comes to maintenance, use a soft, damp cloth to clean the leather regularly. Avoid getting them wet in heavy rain for long periods as it may damage the leather. Store them in a cool, dry place when not in use. If the buckles get loose over time, you can tighten them gently with a small tool. Enjoy your stylish and comfortable sandals!
