Using these boots is easy. Just use the lace-up front to adjust the fit around your calf. The inner side metal zip closure helps you put them on and take them off quickly. The outside hidden zip-closed pocket is great for storing small items like keys or cards. As for sizing, remember that Pleaser shoes are in US sizing. If you're from Australia, make sure to choose 1/2 or 1 size larger than your usual Australian size. For maintenance, use a soft cloth to wipe the vegan patent leather clean. Avoid getting them too wet, as this might damage the material. Since this is a pre-order item, please be patient as it takes about 12 days to reach our warehouse. And if your size is out of stock, we'll get in touch with you right away.
