Using these boots is a breeze. Just unzip the back metal closure, slip your feet in, and buckle up the 5 straps to secure them. For sizing, make sure to follow the conversion if you're in Australia. When it comes to maintenance, use a soft cloth to wipe off dirt and dust regularly. Keep them away from direct sunlight and extreme temperatures to prevent the vegan leather from drying out or getting damaged. Since this is a pre-order item, be patient as it takes about 12 days to reach our warehouse. If you have any questions about the size or if you don't receive your order on time, don't hesitate to contact us.
