O'Keefe Massage Therapy

The OMT Guide to Foot Health

Build a stronger arch, a healthier ankle and a better foundation.

Your feet are doing far more than holding you up.

Every time you stand, walk, turn, climb stairs or push off the ground, the foot is simultaneously managing force, sensing the surface beneath you, adapting its shape, storing and releasing elastic energy, stabilizing the body and helping move blood back up the leg.

A healthy foot is therefore not simply a foot with a "good arch." It is a foot that can feel, adapt, load, spring, stabilize and move. That distinction matters.

At O'Keefe Massage Therapy, I tend to look at the foot less like a rigid foundation and more like an intelligent suspension system. It needs enough mobility to absorb force and adapt to the ground, enough strength to control that movement, enough sensation to tell the nervous system what is happening and enough stiffness at the right moment to propel the body forward.

The goal of foot health is not to make the foot rigid. The goal is to restore and maintain its options.

Understanding the Architecture of the Foot

The human foot contains 26 bones and a remarkably complex system of joints, ligaments, fascia, tendons, nerves, blood vessels and muscles. The foot itself contains 19 intrinsic muscles, while additional muscles originating in the lower leg control the foot through long tendons crossing the ankle.

Structurally, it can be viewed in three regions.

The hindfoot contains the talus and calcaneus. The talus receives the weight of the body from the tibia while the calcaneus forms the heel and provides the large attachment point for the Achilles tendon.

The midfoot contains the navicular, cuboid and three cuneiform bones. This region is central to the architecture and adaptability of the arches.

The forefoot contains the metatarsals and toes. Beneath the first metatarsal head are usually two small sesamoid bones that help the great toe and its flexor system manage considerable force during propulsion.

The ankle itself is not one simple hinge. The talocrural joint, formed between the tibia, fibula and talus, produces most of what we recognize as ankle dorsiflexion and plantarflexion. Below it, the subtalar joint between the talus and calcaneus helps the foot adapt through complex combinations of inversion, eversion, rotation and translation.

Farther forward, the midfoot and forefoot joints allow the foot to deform under load and then become progressively stiffer as the body moves toward push off.

This changing stiffness is one of the most important concepts in understanding healthy feet.

The Arch Is Not One Arch

Most people think of "the arch" as the curve running along the inside of the foot. That is only part of the story.

The foot contains a medial longitudinal arch, a lateral longitudinal arch and a transverse arch crossing the foot from side to side.

The medial longitudinal arch receives most of the attention, but research published in Nature demonstrated that the transverse curvature of the human foot contributes substantially to longitudinal stiffness. In that work, the transverse arch accounted for more than 40 percent of the foot's longitudinal stiffness.

That changes how we should think about arch health. A healthy arch is not simply a high medial arch. It is a three dimensional structure capable of changing shape.

During loading, the foot should deform enough to absorb and distribute force. Later in the stride, it must become sufficiently stiff to create an efficient lever for propulsion.

The arches are supported by bone geometry, ligaments, the plantar fascia, intrinsic foot muscles and several muscles originating in the lower leg. Among the important dynamic contributors are tibialis posterior, fibularis longus, flexor hallucis longus, flexor digitorum longus and the intrinsic muscles under the foot.

So rather than asking, "Is my arch high enough?" a better question is:

"Can my foot control its arch while accepting and producing force?"

The Plantar Fascia: More Than a Tight Band Under the Foot

The plantar fascia is a strong connective tissue structure extending from the calcaneus toward the toes.

When the toes, particularly the great toe, extend during push off, tension increases through the plantar fascia. This contributes to the classic windlass mechanism, helping raise and stiffen the arch so the foot can become a more effective propulsive lever.

But the modern understanding of foot mechanics goes beyond a passive windlass. Researchers have demonstrated that the intrinsic muscles within the arch can actively influence elastic energy storage and return. Flexor digitorum brevis, for example, can contract while its tendinous components stretch and recoil. The researchers described the foot as behaving more like an active suspension system than a passive spring.

That is an important idea for foot health. We do not simply want to stretch the bottom of the foot. We want to maintain the tissue's ability to load, sense force and respond to force.

The plantar fascia and Achilles tendon also have an important mechanical relationship through the calcaneus, although it is inaccurate to describe them simply as one continuous piece of tissue. Anatomical research supports a functional relationship while also showing that complete fiber continuity is not consistently present.

This is one reason calf mobility, calf strength and foot function should rarely be considered separately.

---

Your Foot Is Also a Sensory Organ

This may be the most overlooked aspect of foot health.

The sole of the foot is loaded with sensory receptors continuously reporting pressure, vibration, skin deformation and movement to the nervous system. Four major classes of low threshold cutaneous mechanoreceptors contribute information from the plantar surface. Together with sensory information from muscles, tendons and joints, these signals help the nervous system determine where the body is relative to the ground.

This information contributes to balance, posture, gait and rapid corrections when the ground changes unexpectedly.

Think about stepping onto a rock. Before you consciously analyze what happened, sensory information from the foot has already entered the spinal cord and brain. Your ankle, knee, hip and trunk begin responding.

The foot is therefore both a mechanical interface and a neurological interface between your body and the environment.

Research consistently links plantar sensation with postural control. Reduced plantar sensation, whether from aging or peripheral neuropathy, is associated with impaired balance and increased fall risk.

Do not only strengthen your feet. Keep them neurologically awake.

Walking, varied terrain, appropriate barefoot exposure, balance training and safe sensory stimulation may all provide useful information to the nervous system.

A Quick Map of Foot Innervation

Most sensation and muscular control in the sole ultimately comes through branches of the tibial nerve.

The tibial nerve passes behind the medial ankle through the tarsal tunnel and divides primarily into the medial plantar nerve and lateral plantar nerve.

The medial plantar nerve supplies sensation through much of the medial sole and medial toes while providing motor supply to muscles including abductor hallucis, flexor hallucis brevis and flexor digitorum brevis. The lateral plantar nerve supplies much of the remaining intrinsic musculature and sensation toward the lateral plantar foot.

The top of the foot receives sensory innervation predominantly from the superficial fibular nerve, with the deep fibular nerve serving an important region between the first and second toes. The sural nerve supplies the lateral foot, while the saphenous nerve contributes along the medial side.

Why should a client care about this? Because burning, tingling, persistent numbness, electrical sensations or unexplained sensory changes are not simply "tight fascia." They can represent neural irritation or neurological disease and deserve appropriate evaluation.

---

Blood In: The Arterial System

Healthy feet are metabolically active structures and require a dependable arterial supply. Two primary systems feed the foot.

The anterior tibial artery continues into the foot as the dorsalis pedis artery, supplying the dorsal surface. The posterior tibial artery passes behind the medial ankle and divides into the medial and lateral plantar arteries, supplying the sole.

These arterial systems communicate through the foot, including through the plantar arterial arch, creating important collateral connections.

Two arterial pulse locations are particularly important during clinical examination: the dorsalis pedis pulse on top of the foot and the posterior tibial pulse behind the medial malleolus.

Pulse checks, skin temperature and color can provide clinicians useful information, but they should not be treated as do it yourself diagnostic tests.

---

Blood Out: The Forgotten Foot Pump

The venous side may be even more interesting.

The foot contains dorsal and plantar venous networks. Superficial blood eventually enters vessels such as the great and small saphenous veins, while deep plantar veins communicate with the deep venous system.

The plantar venous system contributes to what is sometimes called the foot pump. When the foot loads and unloads during walking, blood within the plantar venous network is displaced upward. Calf muscle contractions then continue assisting venous return through the leg.

This means the circulation of the lower limb is influenced by movement.

Research measuring venous flow has shown active ankle and foot movements produce considerably greater venous velocities than passive motion, and exercise programs improving calf strength and ankle mobility can improve calf pump function in people with chronic venous insufficiency.

One of the simplest things you can do for your feet and lower legs: move them frequently.

Long periods of sitting followed by no ankle movement remove one of the mechanisms the body normally uses to assist venous return. Ankle circles, ankle pumps, walking and calf contractions are extraordinarily simple interventions with genuine physiology behind them.

The Muscles That Protect the Arch

Healthy feet require cooperation between two muscular systems.

The intrinsic muscles originate and insert within the foot itself. They help control the toes, stabilize the metatarsals, support the arches, modulate stiffness and contribute to balance.

The extrinsic muscles originate in the lower leg and send tendons across the ankle into the foot.

Tibialis posterior provides important dynamic support to the medial arch. Fibularis longus crosses underneath the foot toward the first metatarsal and helps stabilize the transverse and medial architecture. Tibialis anterior controls dorsiflexion and participates in foot positioning. Flexor hallucis longus and flexor digitorum longus contribute to toe control and propulsion. The gastrocnemius and soleus transmit force through the Achilles tendon into the calcaneus and are major producers of ankle plantarflexion and propulsion.

As we age, plantarflexor strength, muscle size and tendon mechanical properties decline, and these changes are associated with reduced walking speed, ankle power and stability.

Maintaining calf strength is not cosmetic. It is part of maintaining the ability to walk powerfully.

---

What About Pronation?

Pronation has acquired an unnecessarily bad reputation.

Pronation is not inherently a dysfunction. It is one of the ways the foot accommodates load and adapts to the ground.

Likewise, a low arch does not automatically mean a weak or unhealthy foot, and a high arch does not automatically mean a strong one.

What matters more is whether the foot can move through its available range under control without persistent pain, instability or progressive deformity.

A foot needs both mobility and stiffness. Too little adaptability can increase loading elsewhere. Too little control can allow motion to exceed what the tissues comfortably tolerate.

The objective is not to freeze the foot in a theoretically perfect position. It is to build capacity.

---

The OMT Foot Health Routine

Research examining intrinsic foot muscle programs generally supports several weeks of consistent training rather than looking for an immediate structural transformation. Reviews suggest intrinsic foot strengthening can improve strength, balance and aspects of arch function, although the overall certainty of evidence ranges from low to moderate depending on the outcome. Short foot programs lasting roughly six to eight weeks appear more meaningful than very short interventions.

The following is an evidence informed maintenance routine rather than a treatment program for a specific injury.

For maintenance, performing the strengthening portion approximately three times per week is reasonable. Foot and ankle exercise trials commonly use training frequencies around three sessions weekly, and longer programs tend to outperform very short interventions.

The objective is not exhaustion. It is increasingly precise control followed by progressively greater capacity.

Once these movements are easy, resistance, single leg loading, reaching, step downs, uneven surfaces and eventually hopping or more athletic tasks can be introduced when appropriate.

---

Your Three Point Foot

One useful cue during standing and exercise is to imagine three areas contacting the ground: the heel, the base of the great toe and the base of the little toe. This is sometimes called the foot tripod.

It is not an instruction to grip the floor. Instead, allow pressure to remain distributed while the arch and toes remain responsive.

If the big toe side of the foot constantly lifts during a calf raise, squat or single leg stance, the body may be avoiding load through an important part of its propulsion system.

If the toes claw violently into the floor merely to maintain balance, the task may currently exceed the foot's ability to control it. Reduce the difficulty and rebuild from there.

---

The Great Toe Matters

The great toe and first metatarsophalangeal joint play an important role in weight bearing, balance and propulsion.

When the great toe extends during the latter part of walking, tension through the plantar fascia contributes to increasing foot stiffness through the windlass mechanism.

That does not mean everyone needs extreme great toe flexibility. It means the joint should retain enough comfortable movement for the activities the person performs.

A useful maintenance practice is simply to move the great toe gently into flexion and extension, then practice keeping it connected to the floor during calf raises and balance work.

Persistent stiffness, swelling or pain at this joint deserves evaluation rather than increasingly aggressive stretching.

---

Train Sensation, Not Just Strength

This is where foot care becomes particularly interesting.

Because plantar sensory information contributes to balance and movement control, carefully exposing healthy feet to different sensory environments may provide useful nervous system input.

Walking barefoot around the home, standing briefly on different safe textures, practicing controlled balance on a firm surface and using gentle manual stimulation of the sole all change the sensory information reaching the nervous system.

This does not mean everyone should throw away their shoes or walk barefoot outdoors. It means that a healthy foot benefits from opportunities to participate in movement rather than being permanently immobilized.

Emerging research continues to investigate plantar sensory stimulation as a rehabilitation strategy. An especially interesting 2026 physiology study found that warming the sole increased the sensitivity of low threshold plantar mechanoreceptors. That does not yet prove that warming the feet improves clinical balance or prevents injury, but it reinforces the concept that plantar sensation is physiologically modifiable.

For a healthy individual, something as simple as warming the feet before mobility and balance training may therefore be an interesting sensory strategy.

Barefoot and Minimalist Training: Useful Tool, Not Religion

Minimalist footwear and barefoot training have become polarizing subjects. The evidence suggests a more reasonable middle ground.

A 2025 systematic review and meta analysis found foot exercises and minimalist footwear can increase aspects of foot strength and modify some biomechanical variables, but the certainty of much of that evidence was low to very low. Another review found increases in intrinsic muscle strength and size after minimalist footwear interventions in healthy individuals.

This does not mean minimalist shoes are universally superior. It suggests that reducing external support can act as a training stimulus for some feet.

The important word is training.

Someone who has spent decades in supportive footwear should not suddenly begin walking miles barefoot or switch immediately to highly minimal shoes. Bones, tendons, fascia and muscles adapt according to loading history. Change the load gradually.

Minimal footwear is best viewed as one possible tool within a larger strategy, not an ideology.

---

Toe Spacers: Potentially Useful, Not Magical

Toe spacers have become another popular foot health tool.

Their most defensible application is in conservative management of conditions such as hallux valgus rather than as a universal requirement for healthy feet. Systematic reviews suggest separators may help certain people with hallux valgus, particularly when combined with exercise or other conservative approaches.

However, a study in healthy young adults found no immediate improvement in ankle range of motion or dynamic balance from simply putting on toe separators.

Use them as a positional or comfort tool if they feel helpful. Do not assume spreading the toes mechanically will substitute for strengthening the foot.

And anything producing numbness, discoloration or significant pressure should be removed.

---

Rolling and Self Massage

A small therapy ball under the foot can feel remarkably effective. It can alter sensation, reduce perceived tension and temporarily change range of motion. Self massage combined with stretching has demonstrated short term effects on ankle flexibility, while newer research in plantar heel pain supports multimodal programs incorporating strengthening, mobility and self massage.

But a useful distinction should be made. You are probably not mechanically "breaking up fascia." Connective tissue is extraordinarily strong.

The immediate effects of rolling are more likely to involve sensory input, pain modulation, local tissue deformation and changes in muscle tone.

Use a ball as input, not punishment.

Thirty to ninety seconds of slow, comfortable pressure is usually more useful than trying to crush the sole of the foot. Then move the foot. The long term adaptation comes from movement and progressive loading.

---

Choosing Shoes

The best shoe is not necessarily the softest shoe, hardest shoe, most minimal shoe or most expensive shoe. It is the shoe that accommodates your foot, fits the activity and allows comfortable movement.

One of the simplest priorities is adequate width. Incorrectly fitted footwear is extremely common and is associated with foot pain, corns, calluses and toe deformities. A 2026 systematic review also identified narrow toed footwear as an important factor associated with hallux valgus.

Your toes should not have to overlap or compress themselves merely to fit inside a shoe. There should be adequate room at the end of the toes, adequate forefoot width and a secure enough heel that the toes do not have to grip continuously to keep the shoe attached.

Beyond that, cushioning, heel height, stiffness and support should reflect individual comfort, activity, symptoms and loading tolerance.

There is no single shoe architecture that every human foot requires.

---

Basic Skin and Nail Health Still Matters

Musculoskeletal health is only one component of healthy feet.

Wash the feet regularly, dry them carefully and pay particular attention to the spaces between the toes. Warm, damp environments promote fungal growth, making breathable footwear, clean socks and adequate drying important.

Toenails generally should be trimmed straight across rather than digging deeply into the corners. Properly fitting shoes also help reduce the risk of ingrown nails.

Look at your feet periodically. Skin changes, unusual callus patterns, blisters and nail changes can reveal loading problems before they become major problems.

Calluses are especially interesting because they often function as a map of repeated pressure. Instead of only asking how to remove them, ask why that area is repeatedly receiving so much load.

---

A Different Way to Think About Foot Health

Instead of constantly asking whether a foot is flat, pronated or structurally imperfect, consider six capacities:

Sensation. Mobility. Strength. Adaptability. Circulation. Load tolerance.

A foot that possesses those capacities can handle an enormous amount of work. A beautiful looking arch without those capacities may not.

Research on intrinsic foot training increasingly supports this functional approach. Foot strengthening programs can improve aspects of dynamic balance and function, while ankle and foot strengthening also appears beneficial for proprioception and postural control.

The foot does not need to be perfectly shaped. It needs to remain useful.

---

When Foot Pain Is Telling You Something Important

Pain should not automatically be interpreted as tissue damage, but neither should persistent foot symptoms be ignored.

Seek appropriate medical or podiatric evaluation when there is persistent or progressive pain, inability to bear weight, significant swelling, repeated ankle giving way, new weakness, burning or numbness, loss of sensation, a wound that does not heal, unexplained skin temperature or color changes, or obvious progressive deformity.

People with diabetes require additional vigilance. The American Diabetes Association recommends routine neurological, skin and vascular foot assessment because peripheral neuropathy and peripheral arterial disease can allow significant injury to develop with surprisingly little pain.

For these individuals, aggressive barefoot training, heat, sharp self treatment of calluses and forceful self massage should not be undertaken casually.

---

The OMT Bottom Line

Your foot was never designed merely to sit inside a shoe. It is a remarkably adaptable piece of human architecture.

It changes shape under load. It stores and returns energy. It senses the ground. It communicates continuously with the nervous system. Its muscles actively change its stiffness. Its movement assists circulation. And every step you take gives it another opportunity to adapt.

Healthy feet do not require endless correction. They require movement, sensation and appropriate load.

Move the ankle. Use the toes. Strengthen the calves. Train the arch. Give the foot room. Let it experience the ground when appropriate. Walk often. And pay attention when sensation, circulation or function begins to change.

The goal is not to create a perfect foot. The goal is to maintain a foot capable of responding to whatever the ground asks of it.
