Tight clothing around the legs as well as tight and poor-fitting shoes may impede circulation in the feet. Ridges around stockings also may stop the circulation in the feet. Smoking decreases circulation to the feet and can cause heart and lung disease, the American Diabetes Association indicates. Obesity, lack of exercise and poor diet also contribute to poor circulation in the feet.
Sores
Sores on the feet as well as infections can occur as symptoms of poor circulation in the feet, MayoClinic.com reports. The decrease of blood flow in the feet decreases the body's ability to fight infection and to heal the sores properly. Sores, which should heal in a few days, may take weeks to go away. Infections occur easily and require medical attention and treatment. Redness around the ulcers and foul-smelling drainage warrant a doctor's attention.
Discoloration
Pale or bluish-tinted skin can occur as symptoms of poor circulation in the feet. This may occur in the whole foot or in individual toes. Both of these discolorations mean blood circulation has reduced. Discoloration may occur in one foot or both feet. The doctor may order a screening for peripheral vascular disease for these kinds of symptoms.
Temperature Differences
One foot may be colder than the other, MayoClinic.com indicates. This symptom may occur even after the person dons warm socks to both feet. The uneven temperature in the feet indicates a change in the circulation of one of the feet.
Numbness and Tingling
A decrease in blood circulation in the feet also may manifest as numbness and tingling. This may feel the same as when a limb "goes to sleep" with the same cause, MayoClinic indicates. Swelling around the ankles may accompany these sensations.
Raised Veins
Raised veins on the feet can indicate poor circulation. They may appear as spider veins that branch out and look like spiders. Such an appearance in the veins may occur simultaneously with pain, MedlineClinic.com indicates.
