Using these boots is a breeze. Just unzip the back metal zip closure and slip your feet in. The 8 buckle straps can be adjusted to your liking for a snug fit. When it comes to sizing, remember if you're in Australia, go 1/2 or 1 size larger than your regular size. Check the sizing tab for exact details. For maintenance, use a soft cloth to wipe off any dirt or dust. Since they're made of vegan leather, avoid getting them wet for long periods. Store them in a cool, dry place. As this is a pre - order item, keep in mind it takes about 12 days for the boots to reach our warehouse from Demonia in the USA. Other items you buy with these boots will be sent with them once they arrive. If by chance Demonia doesn't have your size, we'll get in touch with you quickly.
