Answer: Numb Toes Can be Caused by Simple or Serious Problems. Toes go numb from reduced blood circulation or from nerve damage. If your toes feel numb only during sustained walking, then first try to rule out the most obvious cause - your shoes.
You can have numbness of one (unilateral) or both (bilateral leg numbness) legs. Numbness in the legs may also extend to your toes. Leg numbness is usually due to a lack of blood supply to an area or nerve damage. Leg numbness can also result from infection, inflammation, trauma, and other abnormal processes.
