Using these heels is easy. Just put them on like you would any other pair of shoes and adjust the strap for a comfortable fit. They're perfect for Goth, Lolita, and Cosplay events. When it comes to sizing, remember they're in US sizes. If you're from Australia, get a size 1/2 or 1 size larger than your regular Aussie size. As for maintenance, use a soft cloth to clean the vegan leather. Keep them away from sharp objects to avoid scratches. Since this is a pre - order item, know that it takes about 12 days to reach our warehouse from Demonia in the USA. We'll dispatch your order on the same day it arrives here. If other items are bought with your pre - ordered shoes, we'll hold them and send everything together. In case Demonia doesn't have your size, we'll get in touch with you quickly.
