Using these boots is a breeze. Just unzip the full-length inner side zip closure, slide your feet in, and adjust the straps to your desired tightness. You can also add or remove the oversize bows at the ankle and thigh according to your style preference. When it comes to sizing, make sure to follow the conversion rule if you're from Australia. As for maintenance, use a soft cloth to wipe off any dirt or dust from the polyurethane material. Avoid exposing them to extreme heat or moisture. Since this is a pre-order item, be patient while waiting for your boots to arrive. And in case there's an issue with the size availability, we'll keep you informed right away.
