Diabetic shoes are specially made for diabetics using custom
inserts that are molded to the patient's foot. The purpose of the
diabetic shoe program is to prevent ulcers and amputation in
diabetic patients. It offloads the pressure from a callus or an
ulcer and helps prevent infection. Many diabetics have poor
circulation, poor perspiration, and really can't feel their feet.
They wouldn't know if they had a pebble in their shoe.
