Using these Ziera Xray shoes is a breeze. Just slip your feet in, adjust the straps to your comfort level, and you're ready to go for a whole day of activities. When it comes to maintenance, use a soft, dry cloth to clean off any dirt regularly. Avoid getting the shoes wet for long periods as it might damage the leather. Store them in a cool, dry place when not in use. If you're using orthotics, you can easily insert them into the shoes as they are orthotic - friendly. Keep in mind that the M fit is slightly narrower, so make sure it suits your foot width.
