skin changes — Excessive skin dryness, scaling, and cracking may indicate that circulation to the skin is compromised. Other skin changes may include healed or new ulcers, calluses, and broken skin between the toes .
Deformities — The structure and appearance of the feet and foot joints can indicate diabetic complications. Nerve damage can lead to joint and other foot deformities. The toes may have a peculiar "claw toe" appearance, and the foot arch and other bones may appear collapsed. This destruction of the bones and joints is called Charcot arthropathy.
