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 Demonia shoes are in US sizing. If you're from Australia, size up 1/2 or 1 size. Check the sizing tab for accurate details. For maintenance, use a soft cloth to wipe off dirt regularly. Keep them in a cool, dry place when not in use. Since this is a pre-order item, understand that it takes about 12 days to reach our warehouse from Demonia in the USA. Other items bought with these boots will be sent together. If Demonia runs out of your size, we'll let you know as soon as possible.
