Using these high heels is a breeze. Just unzip the full - length inner side zip and slip your feet in. They're perfect for special occasions like parties or nights out. When it comes to sizing, make sure to convert your Australian size to US size as mentioned. If you're in doubt, check the sizing tab. For maintenance, keep them away from water as the vegan patent leather can get damaged. Use a soft cloth to gently wipe off any dust or dirt. Store them in a cool, dry place, preferably in the shoe box they come in. Since this is a pre - order item, be patient as it takes about 12 days to reach our warehouse. If there are any issues with the size availability, we'll let you know quickly.
