Using these Demonia VIVIKA - 128 ankle boots is easy. Just unzip the inside zipper, slip your feet in, and then lace them up using the D - ring laces. You can adjust the double coffin buckle straps for a better fit. When it comes to sizing, make sure to follow the conversion guide if you're from Australia. For maintenance, keep them away from sharp objects to avoid scratches. Since they're made of vegan leather, you can use a soft, damp cloth to gently wipe them clean. Avoid getting them overly wet as it may damage the material. Remember, this is a pre - order item, so be patient while waiting for your boots to arrive. And in case your size isn't available, we'll reach out to you as soon as possible.
