Using these boots is easy. Just unzip the inside closure and slip your feet in. The multi bat buckle straps add a unique look and can be adjusted for a comfortable fit. When it comes to sizing, make sure to follow the conversion if you're in Australia. As for maintenance, use a soft cloth to wipe off dirt. Since they're made of vegan leather, avoid exposing them to excessive moisture or direct sunlight. For storage, keep them in a cool, dry place. And remember, this is a pre-order item, so be patient while waiting for your boots to arrive. In case there's an issue with the size from Demonia, we'll get in touch with you as soon as possible.
