You may have had bruises that temporarily turned part of your skin a shade of black, blue, or purple. Those injuries usually heal on their own without treatment. But if your foot starts to take on a purple color without any bumps or bruises, you should see your doctor. Purple feet are a sign of a circulation problem that can be potentially serious. When circulation in your feet is healthy, cuts heal quickly and your skin retains its natural color. Blood reaches your feet through a network of arteries, which are the blood vessels that carry blood from your heart.

Blue-purple feet and swelling toes may be caused by Raynaud's disease or diabetes, according to Mayo Clinic and the American Diabetes Association. Both conditions cause circulation problems that result in the discoloration and swelling of the feet. Raynaud's disease is a condition that typically affects the fingers and toes as a result of blood vessel spasming that cuts off sufficient blood flow, explains Mayo Clinic. The condition is more extreme in cold weather, and often results in discolored feet and swollen toes.
