Using these ADORE - 1020 platform boots is super easy. First, unzip the inner side zip closure and then lace up the front as you like. For sizing, if you're in Australia, remember to get 1/2 or 1 size larger than your usual size. As for maintenance, use a soft cloth to wipe off dirt and keep them away from sharp objects to avoid scratching the vegan patent leather. Since this is a pre - order item, be patient as it takes about 12 days to reach our warehouse after the order is placed with Pleaser in the USA. And don't worry, we'll dispatch your order the same day it arrives at our warehouse. If we face any issues like Pleaser not having your size, we'll get in touch with you right away.
