High arched foot can be a structural trait, or it can occur as a consequence of diabetic sensory nerve damage. In high-arched foot, also called cavus foot, the support surface is small and an excessive amount of weight is put on the heel and ball of the foot. This makes the foot prone to ulceration in the strained areas.
The treatment of high-arched foot includes wearing proper footwear. Using orthopaedic soles may become a necessity. A person with diabetes should avoid walking barefoot, especially if they have nerve damage. Indoor shoes should be used and all the footwear should be chosen very carefully.
Your diabetes care provider can assist you with footwear-related matters.
