The ball of the foot is the padded area on the sole just behind your toes, sitting directly beneath the heads of the five metatarsal bones. Pain in this region, broadly called metatarsalgia, ranks among the most common foot complaints and can stem from anything from poorly fitting shoes to nerve irritation to tiny stress fractures. Because so many structures converge in such a small space, pinpointing the cause often requires more than just knowing where it hurts.
What Makes Up the Ball of the Foot
Your forefoot contains five long metatarsal bones, and the rounded ends of those bones (the metatarsal heads) sit right at the ball of the foot. A layer of fat, connective tissue, and skin cushions them from below, and a web of ligaments, tendons, and small joint capsules holds them in alignment from above. Two tiny pea-sized bones called sesamoids are embedded in the tendons under the big toe’s metatarsal head, acting like pulleys to help the big toe push off the ground. When you stand, the ball of the foot bears a large share of your body weight, and during walking or running that load multiplies with each step.
The second metatarsal tends to take the most punishment. A mechanical model of metatarsal loading during distance running estimated that bending strain in the second metatarsal was roughly seven times greater than in the first, with shear force also peaking at the second metatarsal head.1PubMed. A mechanical model of metatarsal stress fracture during distance running That concentration of force explains why pain and injury so frequently target the second and third metatarsal heads rather than the others.
The Most Common Reason It Hurts
“Metatarsalgia” is essentially a catch-all label meaning pain under the metatarsal heads. Doctors subdivide it into primary metatarsalgia, which results from structural or biomechanical issues in the foot itself, and secondary metatarsalgia, which is triggered by something elsewhere in the body. In practice, the distinction matters because treatment differs. Primary metatarsalgia often involves one metatarsal that is disproportionately long or angled in a way that forces it to absorb more ground-reaction force than its neighbors. If you have ever had bunion surgery and then developed new pain under the second or third toe, that is a classic case of what surgeons call transfer metatarsalgia: shortening or shifting the first metatarsal during surgery can redirect pressure laterally, overloading the adjacent metatarsal heads.2PubMed Central. The Effect of First Metatarsal Shortening and Sagittal Displacement on Forefoot Pressure in Minimally Invasive Hallux Valgus Correction
A common assumption is that the fat pad under the metatarsal heads simply wears thin over time, leaving the bones unprotected. That idea sounds logical, but research casts doubt on it. A study measuring fat pad thickness under the second and third metatarsal heads found no meaningful correlation between thinner padding and either the frequency or the intensity of metatarsalgia.3PubMed Central. Plantar fat pad atrophy: a cause of metatarsalgia? That does not mean fat pad changes never contribute, but it does suggest that thinning alone is not the straightforward explanation many people assume.
Morton’s Neuroma and Nerve Pain
If the pain in your ball of foot feels like a burning, tingling, or electric-shock sensation between your toes, a Morton’s neuroma is high on the list of suspects. Despite the name, it is not actually a tumor. It is a thickening of fibrous tissue around a digital nerve, usually in the space between the third and fourth metatarsal heads, sometimes between the second and third. Repetitive irritation and compression cause the nerve sheath to scar and enlarge, producing sharp pain that can radiate into the toes.4PubMed Central. Morton’s neuroma – Current concepts review Tight, narrow shoes are a well-known trigger because they squeeze the metatarsal heads together, pinching the nerve in between. Many people describe temporary relief the moment they take off their shoes and rub the ball of the foot, which is a useful clue that a neuroma rather than a bone problem may be involved.
Interestingly, foot arch type does not seem to make much difference in how a neuroma affects the way you walk. A study comparing people with high arches and flat feet who all had Morton’s neuroma found no significant differences in forefoot pressure distribution or gait between the two groups.5PubMed Central. Is Morton’s neuroma in a pes planus or pes cavus foot lead to differences in pressure distribution and gait parameters? In other words, once a neuroma has developed, the shape of your arch does not obviously change how much trouble it causes.
Plantar Plate Tears
Underneath each of your lesser toes (the four toes beside the big toe), a thick ligament called the plantar plate anchors the toe to the metatarsal head. When this structure tears, the toe can drift upward or sideways and the joint becomes unstable. The result is pain directly under the affected metatarsal head that worsens when you push off during walking. Plantar plate rupture is a significant cause of forefoot pain and deformity at the metatarsophalangeal joint.6Foot & Ankle Orthopaedics. Metatarsophalangeal Joint Instability as a Basis for Radiographic Diagnosis of Plantar Plate Rupture; A Cadaveric Study It tends to affect the second toe most often and is sometimes misdiagnosed as a generic case of metatarsalgia. A tell-tale sign is that the affected toe gradually starts to “cross over” its neighbor. If you notice that happening alongside ball-of-foot pain, a plantar plate injury is worth investigating.
Sesamoiditis and the Big Toe
Pain at the ball of the foot directly under the big toe is a different animal from pain under the lesser metatarsal heads. Here, the two sesamoid bones bear the load, and they can become inflamed (sesamoiditis) or even fracture. Sesamoiditis tends to creep up gradually. It is especially common in runners and dancers who repeatedly push off from the big toe. The condition is considered relatively rare in the broader population and can be easily overlooked, which sometimes leads to delayed treatment and prolonged discomfort.7PubMed Central. Hallucal sesamoiditis on a bipartite sesamoid bone: An uncommon cause of chronic great toe pain A complicating factor is that some people are born with a sesamoid bone that is naturally divided into two pieces (a bipartite sesamoid), which can look like a fracture on an X-ray and confuse the diagnosis.
Stress Fractures
When the mechanical load on a metatarsal exceeds the bone’s ability to remodel and repair, a stress fracture can develop. These are hairline cracks rather than full breaks, and they typically come from a sudden increase in activity: starting a new running program, switching to minimalist shoes without a gradual transition, or ramping up training volume too fast. The second and third metatarsals are the most vulnerable, consistent with the outsized forces those bones experience during forward propulsion.1PubMed. A mechanical model of metatarsal stress fracture during distance running The pain usually starts as a dull ache during activity, progresses to pain during normal walking, and eventually hurts at rest if ignored. Early stress fractures often do not show up on standard X-rays. An MRI or bone scan may be needed if clinical suspicion is high.
Freiberg Disease
A less well-known but significant cause of ball-of-foot pain is Freiberg disease, a condition where the blood supply to a metatarsal head (usually the second) deteriorates, causing the bone to gradually collapse. It is the fourth most common form of osteochondrosis and shows a strong tendency to appear in adolescent female athletes, though it can occur across a wide age range.8PubMed. Freiberg Disease and Avascular Necrosis of the Metatarsal Heads Pain tends to be localized precisely over the affected metatarsal head and worsens with activity. Because it involves structural changes inside the bone, it requires imaging to confirm, and treatment ranges from rest and stiff-soled shoes to surgery in advanced cases.
How High Heels and Shoe Choice Play a Role
Footwear is one of the most modifiable risk factors for ball-of-foot pain, and the data on heel height is unambiguous. As heel height increases, peak pressure under the forefoot rises significantly, shifting toward the first metatarsal head and the big toe.9PubMed. The effects of increasing heel height on forefoot peak pressure Even a modest heel tilts the body’s weight forward, forcing the ball of the foot to absorb forces that the heel and midfoot would normally share. Over time, this can contribute to neuromas, calluses, metatarsalgia, and accelerated wear on the plantar plate.
Sole stiffness matters too, and not always in the direction you would expect. A study of older adults with forefoot pain found that harder shoe soles produced peak pressures across the forefoot that were up to 23% higher than softer soles. Surprisingly, the participants did not rate the softer shoes as more comfortable, despite the measurable pressure reduction.10Gait & Posture. Effects of shoe sole hardness on plantar pressure and comfort in older people with forefoot pain That disconnect between pressure data and perceived comfort is worth knowing: your shoes may be adding stress to the ball of your foot even if they feel fine while you are wearing them.
High Arches, Flat Feet, and Forefoot Loading
If you have unusually high arches, your forefoot and heel take on a disproportionate share of your body weight because the midfoot does not contact the ground as fully. Research confirms that people with high arches report foot pain at substantially higher rates than those with normal arches and show significantly elevated pressure-time integrals under the forefoot.11PubMed. The effect of pes cavus on foot pain and plantar pressure The correlation between higher forefoot pressure and pain held regardless of whether the high arch was idiopathic or related to an underlying neurological condition. For people with high arches who develop ball-of-foot pain, addressing pressure distribution through orthotics or shoe choice is often the first line of treatment.
Rheumatoid Arthritis and the Forefoot
Ball-of-foot pain is not always a local mechanical problem. Systemic inflammatory diseases, especially rheumatoid arthritis, frequently target the forefoot joints early and persistently. Ongoing inflammation in the small joints of the toes leads to cartilage destruction, ligament weakening, and eventual dislocation of the toes at the metatarsophalangeal joints, producing painful calluses and difficulty walking.12Foot & Ankle Orthopaedics. Ultrasonographic Assessment of Synovitis with Lessor Toe Deformity Due to Rheumatoid Arthritis
What makes this particularly tricky is that standard disease-activity scores used to monitor rheumatoid arthritis do not include the foot joints. Even when blood tests and hand-joint exams suggest the disease is in remission, about a quarter to a third of patients still have active inflammation (synovitis) in their foot joints.13PubMed. Active Foot Synovitis in Patients With Rheumatoid Arthritis: Unstable Remission Status, Radiographic Progression, and Worse Functional Outcomes in Patients With Foot Synovitis in Apparent Remission If you have rheumatoid arthritis and your ball-of-foot pain persists despite systemic medications, it is worth asking your rheumatologist whether imaging of the foot joints specifically has been done.
Metatarsal Pads, Bars, and Orthotics
For many causes of ball-of-foot pain, the first practical step is offloading pressure from the affected metatarsal head. Metatarsal pads are small dome-shaped inserts placed just behind the metatarsal heads inside your shoe. The idea is to redistribute weight onto the metatarsal shafts rather than the heads. Studies confirm they work, though results vary by person. In female volunteers, a properly placed metatarsal pad reduced peak metatarsal pressures by roughly 12% to 60%, while male subjects showed more variable responses, with some experiencing pressure increases if the pad was poorly positioned.14PubMed. A quantitative assessment of the effect of metatarsal pads on plantar pressures
Placement turns out to be critical. A study comparing different pad types and positions found that placing the pad slightly distal (toward the toes) tended to produce the best pressure reductions, with an average decrease at the metatarsal heads of about 19% for a small felt pad.15PubMed. Effect of metatarsal pads and their positioning: a quantitative assessment If you buy an adhesive metatarsal pad and stick it too far forward or back, you can actually make things worse, which is why some podiatrists prefer to position them during an in-office visit.
Metatarsal bars, which are built into or attached to the outer sole of the shoe, offer an alternative. Both bars and pads reduce impulse at the second metatarsal head compared with no intervention, but bars are significantly more effective, and an oblique bar orientation outperforms a perpendicular one.16PubMed. Metatarsal bars more effective than metatarsal pads in reducing impulse on the second metatarsal head The trade-off is that bars require shoe modification, which makes them less convenient than a peel-and-stick pad.
When Surgery Enters the Picture
Most ball-of-foot pain responds to conservative measures: better shoes, metatarsal pads, activity modification, and time. When it does not, surgical options exist, though none are simple fixes. For metatarsalgia caused by a disproportionately long or plantarflexed metatarsal, the most widely performed procedure in Europe is the Weil osteotomy, a cut through the metatarsal head that allows the surgeon to shorten or reposition the bone. The technique is effective at relieving pain, but its main complication is postoperative stiffness, with some degree of limited toe flexion or a “floating toe” reported in about 12% to 30% of patients.17Orthopaedics & Traumatology: Surgery & Research. Metatarsalgia
Minimally invasive approaches have gained traction. A distal metatarsal metaphyseal osteotomy (DMMO), performed through a small incision, showed bony healing at three months in the vast majority of patients and produced meaningful improvements in pain and function scores, with late complications in about 8% of cases.18PubMed. Radiographic Outcomes of Minimally Invasive Distal Metatarsal Metaphyseal Osteotomy (DMMO) for primary central metatarsalgia However, both traditional and minimally invasive osteotomies carry the risk of creating transfer metatarsalgia under an adjacent metatarsal, essentially shifting the problem rather than solving it. Poor preoperative planning and surgical technique are frequently cited as contributors to this complication.19PubMed Central. Iatrogenic transfer metatarsalgia after hallux valgus surgery: a comprehensive treatment algorithm That is why imaging the entire forefoot, not just the painful metatarsal, is standard before any surgical decision.
Simple Steps That Actually Help
If you are dealing with ball-of-foot pain and have not yet seen a specialist, a few practical changes are worth trying before anything more involved. Switch to shoes with a wide toe box and a low heel, since even reducing heel height by a centimeter or two lowers forefoot pressure meaningfully. Add a metatarsal pad positioned just behind the painful area, not directly under it. Ice the ball of the foot for 15 to 20 minutes after prolonged standing or walking. If the pain came on suddenly after an uptick in exercise, reduce your mileage or intensity and let the area recover. Persistent pain lasting more than a few weeks, pain that worsens despite rest, or a toe that is visibly drifting out of alignment warrants professional evaluation, since conditions like plantar plate tears, stress fractures, and Freiberg disease can worsen without appropriate treatment.
The ball of the foot is a small patch of anatomy that does an outsized job. Five metatarsal heads, two sesamoid bones, a network of ligaments, and a handful of digital nerves all share that space, and any one of them can be the source of trouble. Knowing which structure is involved is what separates a generic “my foot hurts” complaint from a diagnosis with a clear path forward.
