Unless you are walking across hot coals, you do not expect "burning" feet. Hot sensations anywhere in the body might indicate nerve issues. Or you could have "burning feet syndrome" (Grierson-Gopalan syndrome) which is well known among practitioners but has no definitive cause.

Foot Conditions

The Mayo Clinic lists athlete's foot as a cause of burning feet. Also, Morton's Neuroma (an unnatural nerve growth between the 3rd and 4th toe) may be the cause. Conditions like gout and plantar fasciitis cause burning toes or heat on the bottom of the foot.

Neurological Issues

Diabetic neuropathy is when nerves get damaged because of consistently high blood sugar. The feet are particularly affected. Peripheral neuropathy (nerve damage) due to infection, trauma, or poisoning is another cause of this sensation. Also chronic inflammatory demyelinating polyneuropathy (CIPD) is a neurological disorder that affects the toes.

Vitamin Deficiencies

If you are deficient in vitamins B6, B12, thiamine, or niacin, you can develop burning feet or anemia. Without enough red blood cells to provide oxygen flow, your feet may feel hot and tingle. Although it is believed B vitamins are mostly to blame, this has not been determined scientifically.

Peripheral Artery Disease

Peripheral artery disease is a circulation problem that affects your legs and feet. The condition does not allow you to get enough blood flow to the legs and feet. Feet that feel unusually warm may be the result.

Other

Obesity, gastric bypass surgery, AIDS, rheumatoid arthritis, an allergy to detergent, Grierson-Gopalan syndrome, and complex regional pain syndrome are other possible causes of burning feet. Make sure to see your doctor for a clear diagnosis.
