Your orthotics were crafted using computerized models of your feet. The lab can digitally archive these models so that your doctor can order additional devices, providing your prescription hasn't changed.
You can purchase digital archiving up to one year after the date of manufacturing. You must have the patient name and the device serial number which can be found on the bottom of the orthotics or on the original packaging.
