Using these BEAR - 202 platform boots is easy. First, unzip the inside closure and loosen the laces. Slip your feet in and adjust the laces to your desired tightness for a comfortable fit. Then zip up the inside closure. When it comes to sizing, remember they are in US sizes, so if you're from Australia, size up as recommended. As for maintenance, keep them away from extreme heat and moisture. Use a soft brush to clean off any dirt or dust regularly. Since they are made of vegan suede, avoid using harsh chemicals. If they get wet, let them dry naturally at room temperature. And don't forget, this is a pre - order item, so be patient as it takes time to reach our warehouse and then to you. In case of any issues with the size availability, we'll get in touch with you.
