To use these boots, simply loosen the laces and slip your feet in. You can adjust the laces for a snug fit. Use the inside metal zip closure to make it easier to put on and take off. When it comes to sizing, remember Demonias use US sizing. If you're in Australia, size up 1/2 or 1 size. As for maintenance, use a soft cloth to wipe off any dirt or dust. Keep them away from sharp objects to avoid scratching the vegan leather. Since this is a pre-order item, be patient as it takes about 12 days to reach the warehouse. If your size isn't available, we'll get in touch with you. And when you order other items with these boots, they'll all be sent together once the boots arrive.
