Using these boots is easy. Just lace them up through the eyelets and use the back metal zip closure for a snug fit. The ankle straps with bat buckles can be adjusted according to your comfort. When it comes to sizing, remember if you're in Australia, go 1/2 or 1 size larger than your normal Aussie size. As for maintenance, use a soft cloth to wipe off dirt and dust regularly. Keep them away from direct sunlight and heat to prevent the patent vegan leather from cracking. Since this is a pre-order item, be patient as it takes about 12 days to reach our warehouse. If there's any issue with the size availability, we'll get in touch with you immediately.
