How to Strengthen Your Feet With Simple Daily Exercises

Your feet contain over twenty muscles that respond to training much like your biceps or glutes, and a few minutes of targeted exercise each day can measurably improve arch support, balance, and resistance to common injuries. The challenge is that most people never think to train these muscles at all. Modern shoes do much of the stabilizing work for you, so the small muscles on the sole of your foot rarely get pushed hard enough to grow stronger. Research over the past decade has built a surprisingly solid case that simple, equipment-free exercises can reverse that neglect and produce changes you can feel within weeks.

Why the Muscles Inside Your Foot Matter

When people think about foot support, they usually picture the arch itself, as if it were a fixed bridge. In reality, the arch is a dynamic structure held up partly by connective tissue (the plantar fascia) and partly by layers of small muscles that live entirely within the foot. Researchers call these the intrinsic foot muscles, and they act like a built-in stabilizing system. When scientists blocked the nerves supplying those muscles in a small experiment, the participants’ arches dropped by almost 4 mm on average, confirming that these muscles actively hold the arch up during standing and walking.¹

A influential paper in the British Journal of Sports Medicine drew a parallel between these foot muscles and the deep core muscles of the trunk. Just as your deep abdominal and spinal muscles stabilize the torso before you lift or twist, the intrinsic foot muscles stiffen the arch before your foot pushes off the ground.² That “foot core” concept is now the guiding framework for most of the exercise programs studied in clinical trials. The idea is straightforward: if you train the foot core, the arch gets more support, and the whole lower limb benefits.

The Short Foot Exercise

If there is one move that shows up in nearly every foot-strengthening study, it is the short foot exercise. You sit or stand with your foot flat on the floor, then try to draw the ball of your foot toward your heel without curling your toes. The arch rises and the foot visibly shortens. It looks subtle, almost like nothing is happening, but the contraction targets the deepest layer of sole muscles.

The short foot exercise has been shown to improve arch height and dynamic foot support by actively engaging the plantar muscles, and reviews describe it as an effective, noninvasive strategy for improving foot shape and reducing pain in people with flat feet.³ In older adults, an eight-week program of short foot exercises increased the size of the abductor hallucis, one of the key arch-supporting muscles, and improved navicular height, a clinical measure of how much the arch drops under load.⁴

The tricky part is learning to activate the right muscles. Most people default to scrunching their toes, which fires the wrong set of muscles. A common teaching cue is to imagine you are trying to grip the floor with the arch itself while keeping your toes long and relaxed. It takes practice, and some people benefit from placing a finger under their arch to feel it lift. Once you can do it seated, progress to standing on one foot, then to holding the contraction while doing a single-leg squat or calf raise.

Toe Curls, Grips, and Marble Pickups

Toe-grip exercises are the other big category of foot strengthening, and they are easier to learn than the short foot exercise. Towel scrunches (placing a towel on the floor and pulling it toward you with your toes), marble pickups (grabbing small objects with your toes and dropping them into a cup), and simple toe curls against the floor all train the toe flexors. These muscles matter for push-off power during walking and for grip on uneven surfaces.

A trial in patients with pain under the ball of the foot found that a toe-exercise program improved toe strength, reduced pain scores, and improved single-leg standing time.⁵ In a randomized trial of home-based rehabilitation, people assigned to toe-grasping exercises showed improvements in both grip strength and step length compared to controls.⁶ And in nursing home residents, a toe-grip training program improved not only foot strength and fall-risk scores but also cognitive test performance, likely because the combined physical and coordination demands provided a mild cognitive stimulus.⁷

These exercises work well as something you do while watching television or sitting at a desk. Two to three sets of ten to fifteen repetitions per foot, done daily, is a common starting point in the studies.

Toe Spreading for Big-Toe Alignment

If you have a bunion or notice your big toe drifting toward the smaller toes, toe-spreading exercises deserve special attention. The “toe spread out” exercise asks you to press your big toe down and away from the other toes while simultaneously spreading the smaller toes apart. It targets the abductor hallucis, the muscle that pulls the big toe back into alignment.

An eight-week trial found that combining a toe-spread-out exercise with an orthosis produced a meaningful decrease in the bunion angle along with a significant increase in the cross-sectional area of the abductor hallucis.⁸ A separate study comparing different foot exercises in people with mild bunions found that the toe-spread-out exercise activated the abductor hallucis about three times more than the short foot exercise, and that pressing the big toe outward against a rubber band boosted activation even further.⁹ So if bunion prevention or management is your goal, the toe-spread-out is the higher-yield move.

Improving Flat Feet

Flat feet are one of the most common reasons people look into foot exercises in the first place. A randomized trial of a comprehensive exercise program (including short foot exercises, heel raises, and toe curls) found that after just six weeks, participants with flexible flat feet improved their navicular drop by about 4 mm more than the control group and their arch angle by roughly 16 degrees more.¹⁰ Those are clinically meaningful changes, enough to move someone from a clearly flat foot posture toward a moderate arch.

The key qualifier is “flexible.” If your arch appears when you sit down or stand on tiptoe but disappears when you bear weight normally, you have a flexible flat foot, and exercises can help. If the arch is absent in all positions, the cause may be structural (a bone fusion or severe tendon damage), and exercises alone are unlikely to reshape the foot. Most adults with flat feet fall into the flexible category.

Reducing Running Injuries

One of the most compelling findings in this area comes from a randomized trial of recreational runners. Those who did a foot-core exercise program were roughly 2.4 times less likely to develop a running-related injury over a twelve-month period compared to runners who did not.¹¹ The protective effect was strongest between four and eight months of training, suggesting that the muscles need time to adapt before the benefit kicks in. A secondary analysis of the same trial confirmed that foot-core training was an independent protective factor, with runners in the exercise group having about 60% lower odds of injury.¹²

One thing the research does not show is a direct boost to running performance. A trial that successfully increased toe-flexor strength in runners found no change in running economy or joint mechanics during the gait cycle. The researchers suggested the intrinsic muscles primarily function as arch stabilizers rather than power generators, so stronger foot muscles may keep you healthy without making you faster.¹³ That is still a worthwhile trade-off. An injury-free runner who trains consistently will outperform a faster runner who is sidelined for months.

Balance and Fall Prevention

The foot core system plays a large role in balance, and its capacity declines with age.¹⁴ The small muscles of the sole constantly make micro-adjustments to keep your center of mass over your base of support. When those muscles weaken, your balance suffers, and the risk of falls rises.

The older-adult trial mentioned earlier showed that short foot exercises improved not just muscle size but also functional mobility and fall-risk scores.⁴ Similarly, the nursing-home toe-grip training study found improvements in balance-related test scores.⁷ This matters enormously for older adults, for whom a single fall can trigger a cascade of hospitalization, reduced mobility, and further deconditioning. Foot exercises are low-risk, require no equipment, and can be done seated, making them accessible even for people with limited mobility.

What Barefoot and Minimalist Shoes Add

Going barefoot or wearing minimalist shoes (thin sole, no arch support, no elevated heel) is essentially a passive form of foot training. Your muscles have to work harder because the shoe is not doing the stabilizing for you. Populations that habitually wear minimal footwear have arches that are about 9% higher and roughly 27% stiffer than those of people who wear conventional shoes, along with larger intrinsic foot muscles.¹⁵

For runners who transitioned to minimalist shoes, one study found significant increases in both leg and foot muscle volume, with the growth concentrated in the forefoot muscles.¹⁶ Another trial reported a roughly 11% increase in abductor hallucis cross-sectional area after transitioning to Vibram FiveFingers shoes, though other intrinsic muscles did not change significantly.¹⁷

Minimalist shoes are not a substitute for targeted exercises, and the transition itself carries risk. If you jump straight from a cushioned shoe to a zero-drop minimal shoe and keep running the same mileage, you are loading structures that are not ready for it. A gradual transition over several months, combined with the targeted exercises described above, is a safer approach. Walking around your house barefoot is the gentlest possible starting point and still counts as low-level foot training.

Plantar Fasciitis and Foot Pain

Plantar fasciitis, that stabbing heel pain most noticeable with your first steps in the morning, is one of the conditions most commonly linked to foot weakness. A trial comparing three exercise approaches for plantar fasciitis found that all three groups improved in pain, function, and dynamic lower-limb stability over eight weeks. One group did foot-muscle strengthening alone, another added hip exercises, and a third did only stretching.¹⁸ A systematic review noted that while it is hard to isolate the specific contribution of intrinsic muscle strengthening to plantar fasciitis outcomes, there are indications that high-load resistance training for the plantar fascia can reduce pain and improve function.¹⁹

For self-care, rolling the sole of your foot over a firm ball or a foam roller is a popular complement to strengthening. A randomized trial in plantar fasciitis patients found that foam rolling reduced pain and increased ankle range of motion, with foam rolling outperforming static stretching for improving pressure-pain thresholds in the calf muscles.²⁰ Ball rolling is not a strengthening exercise per se, but it loosens tight tissue and makes the strengthening exercises more comfortable to perform.

Effects Up the Leg

Your foot is the foundation of the kinetic chain, and what happens at the arch ripples upward. When the arch collapses excessively, the shin rotates inward, the knee follows, and the hip compensates. Over time, this can contribute to knee pain, shin splints, and even ACL strain. A review found that strengthening the muscles acting on the foot may have a meaningful impact on ACL and lateral ankle sprain injury risk.²¹

In a trial of patients with patellofemoral pain (pain around and behind the kneecap), adding short foot exercises to a standard hip-and-knee program produced additional improvements. The researchers noted that better foot mechanics can reduce internal tibial rotation and hip adduction, which in turn decreases the lateral compression on the kneecap.²² If you have nagging knee pain and have been told your arches collapse when you squat, foot-core work is worth adding to whatever hip and quad exercises you are already doing.

How Often, How Long, and What to Expect

Most research protocols call for daily practice, five to seven days per week, with each session lasting about fifteen to twenty minutes. A typical 12-week program described in the literature involves roughly 20 minutes of combined isolated and functional foot exercises, performed five times a week with gradual increases in difficulty.²³ That said, something is far better than nothing. Even a five-minute routine tacked onto your morning could help if you are consistent.

In terms of when you will notice changes, the flat-foot trial saw measurable arch improvements at six weeks. The running-injury trial found the protective effect emerging most strongly between four and eight months. Muscle size changes, when measured with ultrasound, typically appear after about eight weeks. Pain relief tends to come sooner than structural change, often within the first few weeks, likely because the muscles start functioning better before they physically grow.

A practical daily routine might look like this:

Short foot holds: 3 sets of 10 seconds per foot, seated progressing to standing
Towel scrunches: 3 sets of 10 repetitions per foot
Toe spreads: 3 sets of 10 repetitions, pressing the big toe outward
Single-leg balance: 3 holds of 20-30 seconds per foot, on a firm surface progressing to a pillow
Heel raises: 2 sets of 15, focusing on pushing off evenly through all five toes

The whole sequence takes about ten to fifteen minutes. The key progression variable is balance challenge: start seated, move to two-legged standing, then single-leg, then single-leg on an unstable surface.

Children and Developing Feet

Flat feet are extremely common in young children and usually resolve on their own as the arch develops. But for children with persistent flat-foot posture, exercise programs can help. A randomized trial of children aged four to seven with flat feet found that both intrinsic and extrinsic muscle strengthening programs improved foot posture, balance, and mobility, with a combined program showing the best results.²⁴ For kids, the exercises often need to be disguised as games: picking up marbles with the toes, “painting” letters on the floor with the big toe, or walking on tiptoes and heels.

The broader takeaway is that foot muscles are trainable at any age. Whether you are a runner trying to stay injury-free, an older adult working on balance, or a parent concerned about a child’s flat feet, the same basic principle applies: the muscles on the bottom of your foot will get stronger if you ask them to work. The exercises are free, require no equipment beyond a towel and a floor, and the worst side effect is mild soreness in muscles you did not know you had.

The Role of What You Feel Underfoot

An interesting newer line of research involves what the sole of your foot senses, not just what the muscles do. The skin on your sole is packed with mechanoreceptors that feed information to the nervous system about pressure, texture, and ground contour. When you walk barefoot on varied surfaces, those receptors send richer signals than when you walk in a cushioned shoe on flat tile. Researchers have found that adding texture to foot orthoses can alter the activation patterns of the intrinsic foot muscles during walking, with the effects depending on where the texture is placed and what phase of the stride you are in.²⁵ A systematic review found moderate evidence that enhanced plantar sensory stimulation can change muscle activity during walking, though the effects depend on the population and the type of stimulation used.²⁶

This does not mean you need textured insoles. The practical implication is simpler: spending some time each day with your feet exposed to varied surfaces, whether that is grass, gravel, a textured mat, or just a carpeted floor, gives your nervous system more input to work with. That richer sensory environment may help the foot muscles activate more effectively, complementing the targeted exercises you are already doing.
