Using these boots is simple. Just unzip the full inner side zipper, slip your feet in, and then lace up through the 17 eyelets. For sizing, make sure to follow the US sizing guide, especially if you're in Australia. When it comes to maintenance, use a soft cloth to wipe off dirt and dust regularly. Keep them in a cool, dry place. Since they're made of vegan leather, avoid exposing them to extreme heat or moisture. As this is a pre - order item, be patient during the waiting period. If you have any issues with the size when they arrive, we'll be happy to assist you.
