Seven short bones cluster in the rear and middle of each foot, anchoring every step from heel strike to toe-off. Together with the longer metatarsals and the smaller toe phalanges, they create the complete 26-bone skeleton of the human foot. Knowing how these seven bones fit together explains why a single twist on a stair can sideline you for weeks, and why your heel often aches more than your toes after a long run.
Below you’ll find each tarsal bone named and located, its role in movement and weight-bearing explained, and a practical way to match common foot pain to the right bone.
The Tarsal Bones Form the Posterior Half of the Foot Skeleton
Short, dense, and arranged in a tight cluster, the tarsals give the foot its shape from the ankle down to the ball of the foot. Each foot contains exactly seven of them, and together they make up the back half of the foot skeleton.
Three bone groups fill the entire foot skeleton, and confusing them is one of the fastest ways to misread anatomy charts:
- Tarsal bones (7 per foot): the rear and middle sections, including the heel and ankle bones.
- Metatarsal bones (5 per foot): the long bones of the forefoot that connect the midfoot to the toes.
- Phalanges (14 per foot): the small toe bones, two per big toe and three per each of the other four.
The naming also trips people up because tarsals sound like carpals. Carpal bones sit in the wrist, not the foot, and the two clusters share no bones, no joints, and no functions despite the similar name. Standard anatomy references treat them as separate skeletal groups, and so should you when you study the foot.
Counting all three groups gives you the 26 bones per foot. Memorize that number, and the rest of the foot skeleton falls into place around it.
Seven Tarsal Bones Grouped Into Hindfoot, Midfoot, and Forefoot
Seven unfamiliar names become manageable once you split them into three regions that match how the foot actually moves. This regional grouping turns memorization into a spatial problem rather than a list-memorization problem, which is how anatomy students usually tackle it.
Hindfoot: Calcaneus and Talus
Two bones anchor the hindfoot. The calcaneus, your heel bone, sits below the ankle and absorbs the first shock of every step. The talus sits directly above it, forming the ankle joint where your shin bones meet your foot. Together these two bones handle all the force that travels down from your leg.
Midfoot: Navicular and Cuboid
Two more bones bridge the hindfoot and forefoot. The navicular sits on the medial, or inner, side just in front of the talus. The cuboid sits on the lateral, or outer, side in front of the calcaneus. These bones act like a flexible keystone between the rigid heel and the mobile forefoot.
Forefoot Tarsals: The Three Cuneiforms
Three cuneiform bones line up side by side just behind the metatarsals: the medial cuneiform closest to the big toe, the intermediate cuneiform in the middle, and the lateral cuneiform closest to the little toe. The name comes from the Latin for wedge, which describes their tapered shape perfectly.
Naming them for their wedge shape only hints at their role; seeing where each one sits and what it does makes the anatomy stick.
Each Tarsal Bone Has a Distinct Location and Identity
Every bone in this cluster has a personality, a location, and a job that none of the others can cover. Walking through each one in turn builds a mental map you can use whenever you point to a spot on the foot.
The calcaneus is the largest tarsal bone and the largest bone in the entire foot. It forms the heel and absorbs impact with every heel strike, whether you’re walking, running, or landing from a jump. Its dense, boxy shape spreads weight across a wide surface.
The talus is the only foot bone with no muscle attachments, because its job is purely mechanical. It articulates directly with the tibia and fibula, the two lower-leg bones, to form the ankle joint, then transfers that load downward into the rest of the foot.
The navicular sits on the inner side of the midfoot between the talus and the cuneiforms. Press your thumb into the arch just below the ankle bone and you’ll feel its bony curve. The cuboid sits opposite it on the outer midfoot, meeting the calcaneus behind and the fourth and fifth metatarsals in front.
The three cuneiforms are wedge-shaped and sit side by side like keys on a keyboard. Each one connects to one of the first three metatarsals: medial cuneiform to the first metatarsal on the big-toe side, intermediate to the second, and lateral to the third. They lock the forefoot to the midfoot and help maintain the transverse arch of the foot.
Once you can place each tarsal, the picture expands from static structure into what those bones actually accomplish under load.
Tip: Picture the foot as a short stone bridge. The calcaneus and talus are the two anchor piers, the navicular and cuboid form the keystone span, and the three cuneiforms are the cobblestones that lock the bridge’s far end to the road beyond.
Tarsal Bones Support Weight, Enable Movement, and Shape the Gait
Mechanically, the tarsal bones do three jobs at once: they bear weight, they move, and they adapt the foot’s shape to whatever surface you’re standing on. Each region of the foot handles a different mix of these jobs.
The calcaneus and talus absorb the body’s full weight with each step and transfer it into the foot. The talus receives load from the tibia, then passes it backward into the calcaneus and forward into the midfoot, acting like a distribution hub.
Midfoot tarsals behave like a flexible bridge that locks and unlocks during walking. When your foot lands, these bones are loose and mobile so the arch can flatten and absorb shock. When you push off, they lock tight so the foot becomes a rigid lever for propulsion. This lock-unlock cycle is called the windlass mechanism, and it is one of the most elegant features of human gait.
The cuneiforms and cuboid act as stable platforms that guide metatarsal alignment and preserve arch height. Without them the forefoot would splay under load, and every step would feel like stepping on a marshmallow.
Walking, running, climbing stairs, and balancing all depend on these mechanics. Runners rely on the windlass mechanism for spring. Stair climbers rely on the subtalar joint for stability. Even standing still requires the tarsals to constantly micro-adjust, which is why tired feet ache after long periods of stillness.
The Tarsal Tunnel and Major Joints Reveal How the Bones Work Together
The bones themselves are only half the story. The way they fit together creates passages and joints that explain some of the most stubborn foot problems you may develop.
The Tarsal Tunnel
A narrow passageway runs along the inner ankle, shielded beneath a ligament known as the flexor retinaculum. The posterior tibial nerve runs through this tunnel along with tendons and blood vessels, all anchored between the talus and calcaneus on one side and the ligament on the other.
When anything in or around the tunnel swells, the nerve gets squeezed. That compression produces burning heel pain, arch pain, and tingling into the sole, the hallmark symptoms of tarsal tunnel syndrome. The pain comes from nerve pressure rather than from a damaged bone, which is why scans often look normal even when your pain is severe.
Major Tarsal Joints
Several named joints shape the way the tarsals move together:
- Subtalar joint: between the talus and calcaneus, allows the foot to tilt inward (inversion) and outward (eversion).
- Transverse tarsal joint (Chopart’s joint): crosses the midfoot and combines the talonavicular and calcaneocuboid joints, controlling the lock-unlock cycle described earlier.
- Tarsometatarsal joints (Lisfranc’s joint): where the three cuneiforms and the cuboid meet the metatarsal bases, the spot where many midfoot injuries occur.
Inversion and eversion, the side-to-side tilting of the foot, come almost entirely from the subtalar joint. The smooth transfer of force from heel to toe depends on all three joint complexes working in sequence, which is why a single stiff joint can throw off your entire gait.
That whole-joint coordination also explains why tarsal injuries rarely stay isolated to one bone or one region.
Common Injuries and Conditions by Tarsal Bone
Foot pain usually points to a specific bone, and recognizing the pattern helps you describe the problem to a healthcare professional. Use the table below as a quick map from symptom to likely source.
| Tarsal Bone | Common Issue | Typical Trigger | Where Pain Shows Up |
|---|---|---|---|
| Calcaneus | Calcaneal fracture, plantar fasciitis, heel spur | Fall from height, repetitive impact, prolonged standing | Bottom or back of the heel |
| Talus | Ankle fracture, osteochondral lesion | Twisting fall, high-impact sport, motor accident | Deep ankle pain, sometimes without visible swelling |
| Navicular | Stress fracture, accessory navicular syndrome | Sprinting, jumping, overuse in athletes | Aching in the inner midfoot arch |
| Cuboid | Cuboid syndrome, fracture | Twisting injury, direct trauma, ankle sprain | Outer midfoot, sometimes with referred arch pain |
| Cuneiforms | Stress fracture, Lisfranc-related injury | Repetitive forefoot load, heavy lifting, twisting | Top or inner forefoot, worsens with push-off |
A few practical patterns help narrow the source further. Heel pain that hurts most with the first steps in the morning often points to the calcaneus and surrounding plantar fascia. Deep ankle pain after a fall, even without obvious swelling, can hide a talus injury. Midfoot aching in a runner that builds over weeks, rather than appearing after a single event, often turns out to be a navicular stress fracture. Outer-foot pain following an ankle sprain sometimes signals the cuboid has shifted out of place, a condition called cuboid syndrome.
Warning: Severe pain, visible deformity, inability to bear weight, or numbness in the foot after an injury warrants prompt evaluation by a qualified healthcare professional. Bone injuries in the foot can look minor on the outside while being serious underneath.
Match the location of your pain to the table above as a starting point, then describe the trigger and timing clearly when you see a clinician. The combination of where it hurts, when it started, and what made it worse gives a specialist a far better starting point than a vague description that doesn’t pinpoint the problem.
The Bottom Line
Seven tarsal bones form the rear and middle of each foot, and they do far more than fill space. The calcaneus and talus carry your full weight at the ankle and heel. The navicular and cuboid form a flexible midfoot bridge. The three cuneiforms lock the forefoot to the arch. Knowing which bone sits where turns confusing foot pain into a clearer conversation and a faster path to the right kind of help.
FAQ
What are the 7 tarsal bones?
Calcaneus, talus, navicular, cuboid, and three cuneiforms (medial, intermediate, and lateral) make up the complete set within the foot. Each foot contains all seven, for a total of 14 across both feet.
Where are the tarsal bones located in the foot?
it occupy the rear half of the foot, from the ankle joint down to the base of the metatarsals. The calcaneus forms the heel, the talus forms the ankle, the navicular and cuboid form the midfoot, and the three cuneiforms sit just behind the metatarsals in the forefoot.
What is the function of the tarsal bones?
it bear body weight, transfer force between the leg and the ground, and create the flexible-yet-rigid structure the foot needs for walking, running, and balancing. They also form the arches that store and release energy with each step.
How do tarsal bones differ from metatarsal bones?
it are short, dense, and clustered in the rear and middle of the foot, while metatarsals are five long bones that span the forefoot and connect to the toes. Tarsals handle weight transfer and arch shape; metatarsals handle leverage and toe-off.
Which tarsal bone is the largest?
Heel-strike impact is absorbed primarily by the calcaneus, the largest of the seven tarsal bones. It forms the entire heel and is also the largest bone in the foot.
What common injuries affect the tarsal bones?
Calcaneal fractures and plantar fasciitis affect the heel. Talus fractures and osteochondral lesions affect the ankle. Navicular stress fractures affect sprinters and jumpers. Cuboid syndrome and cuneiform stress fractures affect the outer and inner midfoot respectively. A qualified healthcare professional can identify the source through exam and imaging.
