Metatarsalgia:
Dr. Naughton’s Ultimate Guide to Symptoms & Biomechanics
"Feeling like there's a pebble in your shoe, or experiencing a burning sensation in the ball of your foot? You aren't alone. Metatarsalgia is a painful overuse injury where the metatarsal heads take too much pressure. The good news is that by simply offloading that pressure, relief is often immediate."

1. What Is Metatarsalgia?
Metatarsalgia (ICD-10 M77.4) refers to pain and inflammation in the ball of the foot. It is not a single disease but rather a symptom of overuse or structural abnormality. It affects the area just before your toes, where the metatarsal heads connect to the phalanges.
Patients often describe it as feeling like they have a "pebble in their shoe" or are walking on a marble. This burning sensation typically worsens with activity and improves with rest.
2. Anatomy: The Ball of the Foot
Your foot has five long metatarsal bones. The "heads" of these bones form the ball of your foot. They bear a tremendous amount of weight during the "push-off" phase of walking.
The Fat Pad
Normally, a specialized fat pad cushions these bones. As we age, this pad thins out, leaving the bones vulnerable to ground impact.
The Transverse Arch
There is a subtle arch going *across* your foot behind the toes. When this arch collapses (splayfoot), the middle metatarsal heads drop down and hit the ground too hard.
Pain Relief Success
A study reported that pain decreased significantly among 84% of participants using metatarsal pads/orthotics.

- Lifts the metatarsal heads
- Restores the transverse arch
- Redistributes weight away from painful spots
3. Symptoms: The "Pebble" Sensation
The pain is usually located just behind the 2nd and 3rd toes.
Burning Pain
A sharp burning feeling in the ball of the foot, especially when walking barefoot.
Pebble Sensation
Feeling like a sock is bunched up or a stone is in your shoe.
Shooting Pain
Electric shocks shooting into the toes (sign of nerve involvement).
Calluses
Hard skin forming directly under the painful bone head.
Home Diagnosis: The "Mulder's Click" Test
Checks for Morton's Neuroma vs. Metatarsalgia.
- 1 Grip your foot around the metatarsal heads (the widest part).
- 2 Squeeze the foot firmly from the sides.
- 3 Result: If you feel a painful "click" or shooting pain, it is likely Morton's Neuroma (nerve). If it just aches, it is likely Metatarsalgia (joint/bone).
Clinical Note
Morton's Neuroma is a thickening of the nerve tissue between the 3rd and 4th toes. Metatarsalgia is a more general inflammation of the joints themselves.

4. Causes: High Heels & High Arches
Primary Causes
- High Heels: Transfers 70-80% of body weight to the ball of the foot.
- High Arches: Lack of shock absorption hammers the metatarsals.
- Hammertoes: Push the metatarsal heads down into the shoe sole.
Risk Factors
- Aging: The protective fat pad naturally thins out.
- Running: High-impact sports increase load significantly.
- Weight Gain: More pressure on the small forefoot bones.
5. Comprehensive Treatments
Home Remedies
- Change Shoes: Switch to flats with a wide toe box immediately.
- Ice: Apply ice for 20 mins to reduce inflammation.
- Rest: Avoid running or jumping until pain subsides.
Medical Therapies
- Metatarsal Pads: A specialized lift placed *behind* the ball of the foot.
- Custom Orthotics: Integrates the pad into a full-length support.
- Callus Shaving: Professional debridement removes the pressure point.
3 Exercises for Metatarsalgia
Tight calves force weight onto the forefoot. Stretch daily.
Why it works: Shifts weight back to the heel.
Grip a towel with your toes.
Why it works: Strengthens the transverse arch.
Flex foot up and down.
Why it works: Reduces swelling in the feet.
6. The Definitive Treatment: Offloading
Why Bilt Labs Is The Superior Choice
To cure metatarsalgia, you must physically lift the weight off the painful bone. Custom Orthotics with Metatarsal Pads are the gold standard.
Metatarsal pads are often in the wrong spot, making pain worse.
We precisely position the dome based on your foot impression to lift the bones accurately.
Correct placement is key: The pad goes BEHIND the ball of the foot, not on it.
Relieve the Pressure
Stop stepping on painful pebbles. Lift and separate your metatarsals today.

Your shoes can be the cure or the cause.
The Orthotic Advantage: Placing a custom orthotic with a metatarsal pad into a cushioned sneaker provides the ultimate defense against forefoot pain.
Wide Toe Box
Allows bones to spread naturally.
Cushioned Sole
Replaces the thinning fat pad.
Rocker Bottom
Reduces pressure during push-off.
Clinical Insight
With custom orthotics, you aren't limited to "orthopedic" shoes. You can add structural stability to your favorite sneakers or work boots instantly.
