Using these boots is easy. First, use the inner side metal zip closure to open the boots. Then, loosen the laces and slip your feet in. Adjust the laces to your desired tightness. For the adjustable hook and straps on the inner side, you can make them tighter or looser for a better fit. When it comes to sizing, remember to follow the conversion rule if you're from Australia. As for maintenance, use a soft cloth to wipe off any dirt on the vegan leather surface. Keep them in a cool, dry place when not in use. Since this is a pre-order item, be patient for about 12 days for them to arrive at our warehouse. And if you have any other items with this pre-order, they'll all come together. In case Demonia doesn't have your size, we'll let you know quickly.
