There are a few different ways for people with diabetes to increase blood flow to their feet. Exercise at least 30 minutes each day for five days a week. Frequency is what you're aiming for, so if needed, exercise in shorter lengths throughout the day so that it adds up to 30 minutes total. Wear diabetic socks that offer plenty of warmth, aren't too tight, and do not have a seam. Stay as close as possible to your targeted level of blood sugar. Avoid smoking. Include omega-3 fatty acids and high-fiber foods in your diet. When you sit or lay down, wiggle your toes for several minutes. This helps blood continue to flow despite being still.
