The key goals of the proposed project are to test whether a specially designed compression device can improve lower extremity perfusion, whilst also simultaneously improving the balance and walking performance. Investigators envision the use of this specially designed offloading device with compression capability will help reduce the incidence of diabetic foot ulcers in high-risk diabetic patients. In addition, investigators assumed the proposed device might enhance daily physical activity as well as walking performance. Investigators will conduct a prospective clinical study to validate these hypotheses. Potential changes in walking and spontaneous daily physical activities will be assessed using validated technologies that include walking analyzer system, balance assessment using body worn sensors, and computerized pressure insoles.
