Using these Emily-375 boots is a breeze. Just lace them up to your desired tightness and use the outer metal zipper for easy on and off. When it comes to sizing, remember to convert from Australian to US sizes as mentioned. For maintenance, keep them away from sharp objects to avoid scratching the vegan stretch leather. Wipe them clean with a soft cloth regularly. Since this is a pre-order item, be patient as it takes about 12 days to reach the warehouse. If you have any other items with your pre-order, they'll be sent together. And in case Demonia runs out of your size, we'll get in touch right away.
