To keep feet in good condition, wash them daily with mild soap and warm water and then dry them carefully — between the toes as well. Apply a little lotion on tops and bottoms to keep skin moist and prevent the cracks that can invite infection. Finally, wear well-fitting, comfortable shoes that protect your feet and can help prevent sores, corns, blisters and other problems.

High blood sugar that remains unchecked raises your risk of poor blood flow and nerve damage to your feet, which can make you prone to foot numbness, sores and lingering infections. If not caught in time, foot ulcers and infections can turn serious, leading to gangrene, and even amputation of a toe, foot or leg.
