The forefoot is the front part of the foot: everything from the ball of the foot forward to the tips of the toes. It is one of three regions, alongside the midfoot arch and the hindfoot, which is the heel and ankle. It takes the load every time you push off, which is why so much foot pain starts there.
Where the Forefoot Begins and Ends
The forefoot has 19 bones. Five are the metatarsals, the long bones that run from the middle of the foot toward the toes. The other 14 are the phalanges, the toe bones. Each toe has three phalanges except the big toe, which has two. The metatarsals are numbered 1 to 5 starting at the big toe, so when a report mentions the “fourth metatarsal,” it means the long bone leading to the fourth toe.
The back border is the Lisfranc joint, where the forefoot meets the midfoot, roughly across the top of the foot where it is highest. It is not a single joint but a cluster of them, where the bases of the long bones fit against four small bones of the midfoot.1PubMed Central. Anatomy of the Lisfranc joint complex: An illustrated review with surgical approach These joints are staggered rather than in a straight line, stepping back about 20 mm from the big-toe side to the outside.2PubMed Central. Anatomy of the Lisfranc joint complex: An illustrated review with surgical approach That staggered fit locks the bases together, which makes this area stiff and stable. A “Lisfranc injury” refers to this boundary joint, and it is often missed as a simple sprain.
You can find the border on your own foot. Press along the top of the foot from the toes back until you feel the bump where the long bones end. The forefoot is roughly the front third to two-fifths of the foot’s length. The ball of the foot, the padded area under the heads of the long bones, is part of the forefoot; your arch belongs to the midfoot.
Each long bone has a base at the back, a shaft in the middle and a rounded head at the front, and doctors use those three names to say where a fracture or tender spot is. The head forms the knuckle-like joint at the base of the toe, where the long bone meets the first toe bone. That is why pain “in the toe” can actually come from the joint at the base of the toe, which sits under the ball of the foot rather than in the free part of the toe.
How the Five Metatarsals Are Arranged
The ends of the metatarsals form a gentle curve, with the second metatarsal typically reaching furthest forward.3PubMed Central. Normal Values of Metatarsal Parabola Arch in Male and Female Feet The first is shorter than the second, and the third, fourth and fifth get steadily shorter, the fifth about 15 to 17% shorter than the second.4PubMed Central. Normal Values of Metatarsal Parabola Arch in Male and Female Feet The curve spreads the push-off across several bones rather than one.
The bones are not equally strong. The first metatarsal is the widest of the five.5PubMed Central. First metatarsophalangeal joint: Embryology, anatomy and biomechanics It is much sturdier in cross-section than the others, even allowing for its length.6PubMed. Cross-sectional geometry of the human forefoot The second to fourth are the weakest despite carrying high pressure, so these middle bones are where stress fractures most often occur.7PubMed. Cross-sectional geometry of the human forefoot Soft tissues such as the plantar fascia and the toe-bending muscles help protect these shafts from strain.8PubMed. Cross-sectional geometry of the human forefoot
A stress fracture usually shows up as pain on top of the foot that grows with walking or running, with tenderness at one spot on the bone. Swelling may appear without any single injury. Early X-rays can look normal, so follow-up imaging may be needed.
The Big Toe Joint and Its Two Small Bones
The big toe joint links the first metatarsal, the first toe bone and two sesamoids, small pea-sized bones under the metatarsal head.9PubMed Central. First metatarsophalangeal joint: Embryology, anatomy and biomechanics The toe can bend a lot up and down but resists side-to-side movement.10PubMed Central. First metatarsophalangeal joint: Embryology, anatomy and biomechanics During sport this joint can carry up to eight times body weight.11PubMed Central. High-Resolution MRI of the First Metatarsophalangeal Joint: Gross Anatomy and Injury Characterization It copes because it is supported by tendons on top, ligaments on the sides and a padded tissue pad underneath that wraps around the sesamoids.12PubMed Central. High-Resolution MRI of the First Metatarsophalangeal Joint: Gross Anatomy and Injury Characterization
The sesamoids absorb shock and protect the tendon that bends the big toe.13PubMed Central. First metatarsophalangeal joint: Embryology, anatomy and biomechanics They also act like pulleys, giving the toe muscles more leverage.14PubMed Central. First metatarsophalangeal joint: Embryology, anatomy and biomechanics The tendon runs between the two small bones, in a groove beneath the metatarsal head, which gives it a better angle to pull and keeps it from being pressed flat under body weight. When the tendon is pinched or the bones are irritated, bending the big toe down, as in pushing off, tends to be the movement that hurts. Pain directly under the big toe joint may therefore involve these bones. Stiffness in the big toe joint changes how you walk and shifts load to other toes.
Sesamoid trouble is easy to mistake for other pain. Sesamoiditis is irritation of these bones, often in dancers and runners. A sesamoid can also fracture from repeated impact. Some people are born with a sesamoid in two pieces, which can resemble a break on X-ray.
Ligaments, Muscles and the Fat Pad
Under each smaller toe joint sits a tough pad called the plantar plate, a term you may see on a scan report.15PubMed. Histologic anatomy of the lesser metatarsophalangeal joint plantar plate The plates join with ligaments running across between the metatarsal heads.16PubMed. Histologic anatomy of the lesser metatarsophalangeal joint plantar plate Together they form a strong band that stops the forefoot from spreading too wide.17PubMed Central. Pathological anatomy and dynamic effect of the displaced plantar plate and the importance of the integrity of the plantar plate-deep transverse metatarsal ligament tie-bar The plantar plate also stops the toe from being pushed upward at its base, which is why damage to it lets the toe lift or drift. These structures are small, so repeated overload, such as long periods on the ball of the foot, can strain them gradually rather than through one injury.
A plantar plate problem classically causes pain under the second toe joint. The toe may drift sideways or lift off the ground, and swelling at the base of the toe is common. Early care can prevent the toe from deforming further.
Small muscles between the metatarsals may brace the forefoot joints when weight is on the ball of the foot.18PubMed Central. The origins and function of the interosseous muscles of the foot Active muscle contraction, not just stretching of the sole’s tissue band, is the main source of foot stiffness at push-off.19PubMed Central. Foot stiffening during the push-off phase of human walking is linked to active muscle contraction, and not the windlass mechanism Simple ways to work them include scrunching a towel with your toes, lifting the big toe alone and then the other toes, and the “short foot” move, where you shorten the foot without curling the toes.
A fat pad under the forefoot acts as a natural shock absorber.20Boston Sports. The Role Of Regenerative Medicine In Orthopedics It can thin with age, past surgery, steroid injections or heavy overload, reducing cushioning.21Boston Sports. The Role Of Regenerative Medicine In Orthopedics
Nerves and Blood Vessels of the Forefoot
Nerves supplying the toes pass along the sole between the metatarsals, splitting near the toe joints. They lie near the toe-joint ligaments and a small fluid sac between the metatarsal heads.22SAGE Journals / Ultrasound. Sonographic anatomy and technique to image the plantar digital nerves and aid identification of a Morton’s neuroma The spaces here are narrow, which makes the nerves vulnerable to pressure. Blood reaches the toes through arteries on the top and the sole of the foot.
An irritated nerve can cause burning or tingling into two neighbouring toes. It may feel like a pebble or a folded sock under the ball of the foot, and taking off tight shoes often brings relief.
Common Problems Rooted in Forefoot Anatomy
A bunion is a progressive deformity in which the big toe leans toward the others and the first metatarsal drifts outward.23PubMed. Hallux valgus and the first metatarsal arch segment: a theoretical biomechanical perspective As the bones shift, the joint capsule weakens and the sesamoids slide out of their groove.24Clinics in Podiatric Medicine and Surgery. Pathologic anatomy of hallux abducto valgus The tendons then pull in a direction that worsens the lean.25Clinics in Podiatric Medicine and Surgery. Pathologic anatomy of hallux abducto valgus One theory is that a flattening arch tilts the first metatarsal and starts the process.26PubMed. Hallux valgus and the first metatarsal arch segment: a theoretical biomechanical perspective
The bump is largely the head of the first long bone sticking out sideways. The joint can become red, swollen and sore where the shoe rubs, and a fluid-filled sac may form over it. Because the deformity changes slowly, many people notice it only when shoes start to pinch.
Pain under the metatarsal heads is called metatarsalgia. Older adults with this pain push down harder under the outer metatarsal heads.27PubMed. Plantar pressures and relative lesser metatarsal lengths in older people with and without forefoot pain Their metatarsals are not unusually long, so stiff toe joints or stiffer sole tissues may raise pressure instead.28PubMed. Plantar pressures and relative lesser metatarsal lengths in older people with and without forefoot pain Metatarsalgia is felt under the weight-bearing heads of the long bones, whereas bunion pain is felt at the side of the big toe joint. It often feels like walking on a stone or bruise, and tends to be worse barefoot or in thin-soled shoes. It can accompany a bunion, because a drifting big toe may pass load on to the other bones.
Morton’s neuroma is a thickened, scarred nerve, usually between the third and fourth toes.29PubMed. Morton’s neuroma: review of anatomy, pathomechanism, and imaging It is not a tumour; it is a compressed nerve.30PubMed. Morton’s neuroma It is linked to overload from foot deformity or tight calf muscles.31PubMed Central. Morton’s interdigital neuroma: instructional review
Wider shoes and padding ease bunion pain but do not reverse it. Metatarsal pads placed just behind the sore spot can offload ball-of-foot pain, and calf stretching may help when tight calves contribute. Surgery is usually considered only when pain persists despite these steps.
How Shoes Affect the Forefoot
Round-toe shoes put less pressure on the big-toe side of the foot than pointed shoes in healthy women.32PubMed Central. The effect of shoe toe box shape and volume on forefoot interdigital and plantar pressures in healthy females In older women with painful bunions, though, the toe-box width of their usual shoes showed no link to pressure on the big-toe side.33PubMed Central. Footwear Toe‐Box Shape and Medial Forefoot Pressures in Women With Hallux Valgus
A bunion bump sits on the side of the joint, so pressure there depends on how the shoe’s material and shape meet the bump, not only on the width of the toe box. Stiff or seamed uppers over the bump can rub even in a roomy shoe, while a softer, stretchy upper can be more comfortable.
For a sore forefoot, shop late in the day when feet are largest, and leave about a thumb’s width beyond the longest toe. A rocker or stiff sole can reduce bending at painful toe joints, and lower heels move weight back off the ball of the foot.
Why the Forefoot Needs Extra Care With Diabetes
With nerve damage from diabetes, high pressure under the foot is a proven ulcer risk.34PubMed. Contribution of plantar fascia to the increased forefoot pressures in diabetic patients People with severe nerve damage had roughly double the forefoot pressure of those without.35PubMed. The forefoot-to-rearfoot plantar pressure ratio is increased in severe diabetic neuropathy and can predict foot ulceration Heel pressure did not predict ulcers, only forefoot pressure did.36PubMed. The forefoot-to-rearfoot plantar pressure ratio is increased in severe diabetic neuropathy and can predict foot ulceration
Use a mirror to look under the metatarsal heads, and watch for calluses, redness or blisters that may hide damage. Never walk barefoot. If pressure areas appear, see a foot specialist about cushioned insoles.
A callus forms where pressure is repeated, and with reduced feeling a person may not notice it building up. Thick hard skin can itself raise pressure on the tissue underneath, so ulcers can begin beneath a callus without any pain. A podiatrist or foot specialist should trim calluses rather than the person doing it at home with blades or chemical corn removers.
How Doctors Examine the Forefoot
Plain X-rays are usually enough to assess most forefoot fractures and dislocations.37PubMed Central. High-resolution ultrasound and MRI in the evaluation of the forefoot and midfoot X-rays taken standing, of both feet, help reveal subtle shifts at the Lisfranc joint.38PubMed Central. High-resolution ultrasound and MRI in the evaluation of the forefoot and midfoot Ultrasound or MRI shows soft tissues such as nerves and plantar plates.39PubMed Central. High-resolution ultrasound and MRI in the evaluation of the forefoot and midfoot
Weight on the foot makes a damaged joint show its true alignment. Comparing the injured side with the other foot helps show whether a small gap between bones is a real change or the person’s normal anatomy. That is why an injury that seemed minor may be followed by repeat imaging under load.
At the appointment, the doctor presses each metatarsal head and squeezes the forefoot, and watches you walk and stand. Bring the shoes you wear most, and describe where the pain sits and when it starts.
