Using these boots is easy - just unzip the back metal closure, slip your feet in, and fasten the 3 buckle straps with heart - shaped metal plates. When it comes to sizing, remember they're in US sizes. If you're from Australia, pick 1/2 or 1 size larger than your normal size. For maintenance, use a soft cloth to wipe off dirt regularly. Since they're made of vegan leather, avoid getting them wet for long periods as it might damage the material. And because this is a pre - order item, be patient as it takes about 12 days to reach our warehouse from Demonia in the USA. We'll send your order out the same day it arrives here. If Demonia runs out of your size, we'll let you know right away.
