Using these Demonia WAVE - 110 platform boots is easy. Just unzip the inside and back metal zippers to put them on and zip them up when you're ready to go. Since they're pre - order items, be patient as it takes around 12 days for them to reach our warehouse from Demonia in the USA. When it comes to sizing, remember to convert from Australian to US sizes by going 1/2 or 1 size larger. For maintenance, use a soft cloth to wipe off dirt and keep them away from sharp objects to avoid scratching the vegan leather. If they get wet, let them dry naturally. And don't worry, these boots are 100% vegan and cruelty - free, so you can wear them with a clear conscience.
