What causes burning feet?

First: I Suggest you take medical problems to a medical professional, not random people on the Internet

Do you know if you have Diabetes? Peripheral neuropathy is a common symptom.
Athletes foot? Recent exposure to extreme cold? Do you have a history of vascular problems?

There are also some really alarming other possibilities

So I recommend that if this is a new symptom, or persistent, and not previously explained, that you have it looked at by a doctor or nurse ASAP.

Are you diabetic? I'm no doctor but my wife is diabetic and has diabetic neuropathy in her feet. When her blood sugar spikes high, her feet cause her pain too. I have pain and burning in my feet also but it is caused by nerve damage in my spine. For me, the longer I stand or walk, the stronger the pain gets. I would see a doctor if I were you. If possible, when your pain comes on so that they can test your sugar during your symptoms. This would be something that the nurse could do, probably without an appointment depending upon your relationship with your doctor. Good luck.
