Metatarsalgia is a generic term indicating pain localized in the front part of the foot, in the region of the metatarsal heads — the bony prominences that form the “ball” of the foot, just before the toes. It is one of the most common causes of foot pain, with an estimated prevalence of 10% in the general population and much higher percentages in athletes and women who wear high-heeled footwear.

The pain is typically described as a sensation of “walking on pebbles” or “having a stone in the shoe.” It worsens with prolonged standing, walking barefoot on hard surfaces, and with inadequate footwear. It improves with rest and by taking off shoes.

Metatarsalgia is not a specific diagnosis but a symptom that can have multiple causes. Conservative treatment — with custom orthotics, exercises, and appropriate footwear — is effective in the vast majority of cases.

Anatomy: The Forefoot

The forefoot is composed of five metatarsal bones (numbered I to V, from the big toe to the little toe) and the phalanges of the toes. The metatarsal heads are the distal ends of the metatarsals that form the anterior support of the foot.

During the push-off phase of gait, the forefoot bears up to 125% of body weight. The load is normally distributed evenly among all metatarsal heads, with a greater percentage on the I metatarsal (big toe) thanks to the “windlass” mechanism of the plantar fascia.

When load distribution is altered — due to foot deformities, inadequate footwear, or overload — one or more metatarsal heads experience excessive load, causing inflammation, pain, and the formation of calluses (hyperkeratosis).

Causes

Biomechanical Causes

  • Pes cavus (high arch foot): the high arch concentrates the load on the metatarsal heads
  • Hallux valgus (bunion): the deformity of the big toe transfers the load from the I metatarsal (which normally bears 30% of the load) to the lateral metatarsals (II and III)
  • Hallux rigidus (stiff big toe): the limitation of big toe dorsiflexion prevents the correct propulsion mechanism, overloading the central metatarsals
  • Hammer or claw toes: the deformity of the toes exposes the metatarsal heads to direct load
  • Long metatarsal (foot formula): a II metatarsal longer than the I (Greek foot) concentrates the load on its head
  • Flat foot or pronated foot: can alter load distribution

Footwear

  • High heels: a 7 cm heel transfers 80% of body weight to the forefoot (vs 50% barefoot)
  • Tight shoes: compress the forefoot, promoting deformities
  • Thin and hard soles: do not cushion impacts
  • Worn-out shoes: lose their cushioning capacity

Sports Overload

  • Running: the forefoot undergoes repeated loads with each step
  • Jumping: basketball, volleyball, athletics
  • Dance: especially ballet (on pointe)
  • Football/Soccer: running on hard surfaces and the kicking motion

Other Causes

  • Overweight: increases the load on the forefoot
  • Age: the fat pad under the metatarsal heads thins with aging, reducing natural cushioning
  • Metatarsal stress fractures: repeated overload causing microfractures (frequent in the II and III metatarsals)
  • Morton’s neuroma: a thickening of the interdigital nerve causing burning pain between the metatarsal heads (typically between III and IV)
  • Rheumatoid arthritis: inflammation of the metatarsophalangeal joints
  • Metatarsophalangeal synovitis: inflammation of the joint capsules

Symptoms

Pain

  • Location: under the forefoot, in the region of the metatarsal heads (II, III, and IV are most affected)
  • Character: dull, burning pain, “like walking on pebbles”
  • Worsening: prolonged standing, walking (especially barefoot on hard surfaces), running, high heels
  • Improvement: rest, taking off shoes, massage
  • Calluses: the formation of calluses (hyperkeratosis) under overloaded metatarsal heads is an indirect sign of abnormal load distribution

Warning Symptoms

Consult your doctor or physical therapist if:

  • The pain is acute and sudden after an increase in activity (suspicion of stress fracture)
  • The pain is burning and radiates to the toes with a shock-like sensation (suspicion of Morton’s neuroma)
  • The joints are swollen, warm, and painful (suspicion of arthritis)

Diagnosis

Clinical Examination

  • Foot inspection: deformities (hallux valgus, hammer toes, pes cavus), calluses
  • Palpation: pain on pressure of individual metatarsal heads (squeeze test)
  • Metatarsal formula assessment: relative length of the metatarsals
  • Mobility assessment: dorsiflexion of the big toe, metatarsophalangeal mobility
  • Gait analysis: observation of walking and plantar support
  • Postural assessment: alignment of the kinetic chain, pelvis, and lower limbs

Imaging Diagnostics

  • Weight-bearing X-ray: shows metatarsal formula, deformities, stress fractures (in late stages), signs of arthritis
  • Ultrasound: useful for Morton’s neuroma (visualizes the neuroma), synovitis, and bursitis
  • MRI: for early stress fractures (not visible on X-ray), Morton’s neuroma, plantar plate lesions
  • Baropodometry: plantar load examination — identifies areas of hyperpressure and guides orthotic prescription

Treatment

Custom Orthotics

Orthotics are the most effective treatment for metatarsalgia:

  • Metatarsal dome/pad: a raise positioned behind the metatarsal heads that redistributes the load, offloading painful areas
  • Metatarsal offloading: a “window” in the orthotic under the overloaded metatarsal head
  • Arch support: for flat or pronated feet
  • Cushioning materials: the orthotic must be made of materials that absorb impacts

Orthotic prescription should be based on a clinical and baropodometric evaluation. Your doctor or physical therapist or specialist podiatrist will recommend the most suitable orthotic.

Footwear

  • Shoes with rigid rocker sole: the rocker sole reduces pressure on the forefoot during the propulsion phase
  • Wide toe box: to accommodate the forefoot without compression
  • Low heel: maximum 3-4 cm for daily use
  • Good cushioning: sole with adequate impact absorption capacity

Physiotherapy

  • Manual therapy: mobilization of metatarsophalangeal joints and metatarsals
  • Stretching: of leg and foot muscles (gastrocnemius, soleus, plantar fascia)
  • Strengthening: of intrinsic foot muscles to improve arch support and load distribution
  • Taping: tapes that offload the metatarsal heads
  • Shockwave therapy: effective for chronic resistant forms

Medications

  • Topical NSAIDs (gel) applied to the painful area
  • Ice: 15-20 minutes after activities
  • Corticosteroid injections: under ultrasound guidance for metatarsal synovitis or bursitis

Exercises for Metatarsalgia

The forefoot comprises five metatarsal bones and toe phalanges; metatarsalgia is pain under the metatarsal heads caused by abnormal load distribution during weight-bearing activities. Exercises aim to strengthen the intrinsic foot muscles, improve metatarsophalangeal joint mobility, and stretch leg muscles. Your doctor or physical therapist will adapt the program.

Strengthening Intrinsic Foot Muscles

Recovery Times

Cause Indicative Times
Metatarsalgia from footwear 2-4 weeks with footwear change and orthotics
Biomechanical metatarsalgia 6-12 weeks with orthotics and exercises
Stress fracture 6-8 weeks with offloading and rest
Morton’s neuroma Variable, from weeks to months

Prevention

  • Appropriate footwear: avoid high heels and tight shoes, prefer cushioning shoes with a wide toe box
  • Orthotics: if pes cavus or hallux valgus is present
  • Strengthening intrinsic foot muscles: daily exercises
  • Regular stretching: gastrocnemius, soleus, plantar fascia
  • Weight management: overweight increases the load on the forefoot
  • Gradual progression of sports activity: avoid sudden increases in running volume

Frequently Asked Questions (FAQ)

Does metatarsalgia heal?

Yes, metatarsalgia responds very well to conservative treatment (orthotics, footwear, exercises). Once the biomechanical cause is corrected or inadequate footwear is removed, the pain improves in a few weeks. Surgery is rarely necessary.

What shoes should I use for metatarsalgia?

Ideal shoes have: a wide toe box that does not compress the forefoot, a rigid rocker sole, good cushioning, and a low heel (max 3-4 cm). Avoid: high heels, tight and pointed shoes, flip-flops, flat and thin-soled shoes. Your doctor or physical therapist or podiatrist will recommend the most suitable shoes.

Are orthotics essential for metatarsalgia?

Orthotics with a metatarsal dome/pad are the most effective treatment for biomechanical metatarsalgia. They are not always essential (if the cause is only inadequate footwear, changing it is enough), but in most cases, they significantly accelerate recovery. Custom orthotics based on baropodometry are preferable to generic insoles.

Is metatarsalgia the same as Morton’s neuroma?

No. Metatarsalgia is a generic forefoot pain; Morton’s neuroma is a specific cause of metatarsalgia: a thickening of the interdigital nerve (typically between the III and IV toes) that causes burning pain and tingling in the toes. Neuroma requires specific treatment (orthotics with a raise, infiltrations, possibly surgery).

Can I run with metatarsalgia?

During the acute phase, it is advisable to reduce or suspend running, replacing it with low-impact activities (swimming, cycling). Running should be resumed with appropriate footwear and possibly with sports orthotics, on soft surfaces (grass, dirt), gradually increasing volume. Your doctor or physical therapist will guide your return to running.

Do high heels cause metatarsalgia?

Yes, high heels are one of the main causes of metatarsalgia. A 7 cm heel transfers 80% of body weight to the forefoot (vs 50% without a heel). Prolonged use of high heels causes chronic overload of the metatarsal heads, promotes hallux valgus, hammer toes, and Morton’s neuroma. If you cannot avoid them completely, limit their use and alternate with low-heeled shoes.
