There are a number of reasons why your feet may feel numb. You may have a condition called peripheral neuropathy, where the nerves in your feet are not functioning properly, and are therefore not giving your brain all of the information about your feet.
Neuropathy can have many different causes, including diabetes, vitamin deficiency, back problems, chemotherapy, autoimmune or inherited conditions, infection, excessive alcohol intake, and kidney, liver, or thyroid problems.
It is very important for anyone with numbness to carefully check his/her feet every day, as you might have a wound or other problem that you cannot feel because of the nerve problems. Additionally, you should see a doctor to learn why the numbness is occurring, and the possible treatment options for your condition.
