What Are the Main Nerves in the Feet?
The feet are supplied by five main nerves: the tibial nerve (which splits into the medial and lateral plantar nerves), the sural nerve, the superficial peroneal nerve, the deep peroneal nerve and the saphenous nerve, and together they carry touch, pain and temperature signals and control the small muscles of the foot. Damage to any of them can cause numbness, tingling, burning or weakness.
Foot Nerves at a Glance
| Nerve | Where It Runs | What It Supplies | Common Problem |
|---|---|---|---|
| Tibial nerve | Behind the ankle through the tarsal tunnel | Splits into plantar nerves for the sole | Tarsal tunnel syndrome |
| Medial and lateral plantar nerves | Sole of the foot | Sole sensation, small foot muscles | Burning sole, Morton's neuroma area |
| Sural nerve | Back of the calf to the outer ankle and foot | Outer foot and little toe sensation | Injury or entrapment |
| Superficial peroneal nerve | Outer lower leg to the top of the foot | Top of the foot and toes | Compression from tight shoes or ankle sprains |
| Deep peroneal nerve | Front of the shin to the top of the foot | Space between the big and second toes, lifts the foot | Foot drop, numb big toe |
| Saphenous nerve | Inner leg to the inner ankle | Inner ankle and foot sensation | Injury |
Common Conditions That Affect Foot Nerves
- Tarsal tunnel syndrome: pressure on the tibial nerve behind the ankle, causing burning or tingling in the sole.
- Morton's neuroma: thickened nerve between the toes, causing burning pain and a feeling of a pebble in the shoe.
- Peroneal nerve entrapment: numbness on the top of the foot or foot drop.
- Peripheral neuropathy: damage to many nerves at once, usually both feet. See neuropathy in the feet.
Neuropathy or a Pinched Nerve?
| Feature | Neuropathy | Single Nerve Problem |
|---|---|---|
| Feet affected | Usually both | Often one |
| Area | Toes and feet, stocking pattern | A specific area of the foot |
| Trigger | No clear trigger | Certain shoes or positions |
| Common causes | Diabetes, B12 deficiency, alcohol | Pressure, injury, bone changes |
See numb toes and foot numbness treatment for more on how patterns point to a cause.
How Nerves in the Feet Get Damaged
- Blood sugar and poor blood flow starve the longest nerves first.
- Pressure from tight shoes or repeated impact.
- Injury, such as ankle sprains or fractures.
- Toxins, vitamin deficiencies and medicines.
How Foot Nerve Problems Are Tested
- Physical exam: your doctor taps over the nerve behind the ankle (Tinel's sign), checks reflexes and tests touch, vibration and the monofilament.
- Nerve conduction studies and EMG: measure how well signals travel in the larger nerves and whether muscles are responding.
- Ultrasound or MRI: can show pressure on a nerve from a cyst, scar tissue or a bony change.
- Blood tests: look for diabetes, B12 deficiency, thyroid or kidney problems.
- Skin biopsy: counts tiny fibers when other nerve tests look normal.
Which Specialist Treats Foot Nerve Problems?
Start with your primary care provider. Depending on the cause, you may be referred to a podiatrist for tarsal tunnel or Morton's neuroma, a neurologist for neuropathy or an unclear cause, an endocrinologist for diabetes, or a physical therapist for strength and balance.
Protecting Foot Nerves
- Wear wide, cushioned shoes (shoe guide).
- Control blood sugar and get B12 checked.
- Check your feet daily.
- Stay active with low-impact exercise.
- Keep skin supple with a nightly neuropathy foot cream, avoiding broken skin.

Frequently Asked Questions
How many nerves are in the foot?
Five main nerves supply the foot, with many small branches reaching the toes and skin.
What nerve causes burning in the sole of the foot?
The plantar nerves, branches of the tibial nerve, are often involved, from tarsal tunnel compression or from neuropathy.
Can foot nerves heal?
Peripheral nerves can regrow slowly, about a millimeter a day, if the cause is removed and the nerve cell survives.
What causes a pinched nerve in the foot?
Tight or narrow shoes, repeated pressure, ankle injuries, swelling and bone changes such as bunions can compress a nerve. Changing footwear and getting an exam usually come first.
Can a pinched nerve in the foot go away on its own?
Mild cases often settle once the pressure is removed, for example by switching to wider shoes. Symptoms that last more than a few weeks or come with weakness need a medical evaluation.
Key Takeaways
- Five main nerves supply the foot.
- Single-nerve problems differ from neuropathy, which usually affects both feet.
- Shoes, blood sugar and B12 are the main factors you can control.
- Persistent symptoms deserve a medical check.
