Using these Demonia platform boots is a breeze. Just use the inner side zipper to easily slip them on and off, and then adjust the laces for a snug fit. When it comes to sizing, make sure to check the US sizing and convert from Australian sizes if needed. As for maintenance, keep them clean by gently wiping with a damp cloth. Avoid exposing them to extreme heat or moisture, as this could damage the vegan leather. Since these are pre - order items, be patient as they take about 12 days to reach our warehouse.
