The Miracle uses the same healing technology found in band-aides. Nano-silver particles are sprayed on a layer of soft material in the lining of the sole and box, allowing constant contact with the foot to promote healing. This technology neutralizes the harmful bacteria and fungi that cause unpleasant odors and infections. The Miracle is made on the same last as the 2007 but has a lower heel. Its flexible and elastic materials adapt to the shape of the foot the moment it is tried on. This shoe is incredibly comfortable and can be worn without toe pads!
