When the loss of sensation in the feet is caused by lack of blood supply, sensation returns quickly once individuals move their legs and feet, explains Healthgrades. When foot numbness is chronic, then there is probably some level of nerve damage causing the issue.

Nerves can sustain damage and cause foot numbness as a result of moderate to serious orthopedic conditions, including degenerative disk disease, herniated disk, back injury, osteoporosis and nerve entrapment, according to Healthgrades. Neurological conditions that cause nerve entrapment or damage that leads to foot numbness include diabetic neuropathy, vitamin B12 deficiency, multiple sclerosis, heavy metal poisoning and alcoholism.

Foot numbness can be caused by more serious underlying circulatory conditions, according to Healthgrades. Possible circulatory causes include deep vein thrombosis, which is a blood clot in the lower leg. Other causes related to the circulatory system include peripheral artery disease, in which blood flow to the lower extremities is restricted due to arteries narrowed by fat and cholesterol buildup, and Buerger’s disease.
