To use these boots, simply unzip the full inside closure and slip your feet in. The stretchy design will fit snugly around your thighs. When walking, the 5' heel will give you a confident stride. As for sizing, make sure to check the conversion if you're from Australia. Since these are pre-order items, be patient as it takes about 12 days for them to reach our warehouse. When it comes to maintenance, use a soft cloth to wipe the vegan patent leather clean. Avoid getting them wet for long periods as it may damage the material. If you notice any scratches, a little leather conditioner can help restore their shine. And remember, if Pleaser doesn't have your size in stock, we'll let you know as soon as possible.
