To wear these sandals, simply unzip the back metal closure and slide your foot in. Then, fasten the 4 buckle straps to your desired tightness. When it comes to sizing, make sure to follow the conversion guide if you're from Australia. For maintenance, use a soft cloth to gently clean the vegan leather. Avoid getting them wet for long periods as it might damage the material. Since this is a pre-order item, be patient as it takes around 12 days to reach our warehouse. If there are any issues with your size not being available, we'll reach out to you. And remember, other items you bought with these sandals will be sent together once they arrive.
