How to Fix Ankles That Roll In (Overpronation)

Overpronation responds to a combination of targeted strengthening, improved ankle mobility, supportive footwear, and sometimes orthotics. The ankles roll inward because the muscles and tendons responsible for holding up the arch and controlling the heel cannot keep up with the demands placed on them, and fixing the problem means addressing those specific weak links rather than just bracing against the motion. The approach that works best depends on why your feet are pronating in the first place, which varies more than most people realize.

What Is Actually Happening When Your Ankles Roll In

When you stand or walk, your foot naturally rolls slightly inward as it absorbs the impact of each step. This inward roll is called pronation, and a modest amount of it is normal and healthy. Overpronation is what happens when the foot rolls too far inward, causing the arch to flatten excessively and the ankle bone to visibly tilt toward the midline. The navicular bone, the small bone on the inner side of your foot just in front of the ankle, drops noticeably toward the ground. That drop is measurable: clinicians check it by comparing the height of the navicular when your foot is in a neutral position versus when it relaxes into its natural standing posture.¹

The navicular drop test is simple enough to approximate at home. Sit in a chair with your feet flat on the floor, knees bent at a right angle, and have someone mark or note where the navicular bone sits. Then stand up and relax fully into your normal posture. If that bone drops more than about 10 millimeters, you are likely overpronating. Research has connected pronated feet not only to foot and ankle pain but also to issues further up the chain, including chronic low back pain.²

The Root Causes Are Usually Muscular, Not Skeletal

People often assume overpronation is a bone-structure problem they are born with, and while skeletal anatomy plays a role, the more common and more fixable causes are muscular. Three main culprits deserve attention.

The first is the posterior tibial tendon. This tendon runs behind the inner ankle bone and is the primary dynamic stabilizer of the arch. When it weakens or degenerates, the arch loses its main support, and the foot flattens out under load. Posterior tibial tendon dysfunction is the most common cause of adult-acquired flatfoot, and when left untreated it progresses from mild pain and weakness to visible deformity and joint damage.³ People with this dysfunction show significantly greater rearfoot eversion and arch collapse compared to healthy controls.⁴

The second culprit is the group of small muscles on the sole of your foot, called the intrinsic foot muscles. These muscles maintain the arch’s shape and help distribute force during walking.⁵ When researchers electrically stimulated these muscles in lab settings, the arch stiffened and lifted, directly counteracting the flattening that happens under load.⁶ Conversely, when these muscles fatigue, navicular drop increases, meaning the arch collapses further.⁷ If you notice your feet rolling in more at the end of a long day or toward the end of a run, intrinsic muscle fatigue is a likely contributor.

The third is limited ankle dorsiflexion, the ability to pull your toes toward your shin. When you cannot bend your ankle far enough, your foot compensates by collapsing inward to find the range of motion it needs. A systematic review identified limited dorsiflexion as one of the main factors causing overpronation.⁸ Tight calves are extremely common in people who sit at a desk all day or who wear heeled shoes regularly, making this one of the easiest causes to screen for and address.

Exercises That Target the Problem

The most-studied exercise for overpronation is the short foot exercise. You perform it by sitting or standing and trying to shorten the sole of your foot by pulling the ball of the foot toward the heel without curling the toes. Imagine you are trying to dome the arch upward using only the muscles on the bottom of your foot. This exercise activates the intrinsic foot muscles that support the arch and has been shown to improve arch height, foot posture, and pain levels.⁹ In clinical trials, short foot exercises significantly improved navicular drop and foot posture scores, with large effect sizes.¹⁰

Strengthening the tibialis posterior muscle, the one behind the inner ankle, is the other critical piece. Two exercises commonly used in research are foot adduction resistance and foot supination resistance, both performed with an elastic band. For the adduction exercise, you sit with your foot flat on the floor while the band pulls it outward, and you resist by sweeping the foot inward. For the supination exercise, you stand on the edge of a step and turn the sole of the foot inward against resistance.¹¹ A six-week program combining tibialis posterior strengthening with iliopsoas stretching improved navicular drop, muscle activation, and dynamic balance in young adults with flat feet.¹²

A reasonable starting routine would combine short foot exercises, banded tibialis posterior work, and calf stretching. Performing these three to five days per week for at least six weeks is the window most studies used to demonstrate meaningful improvement. You do not need exotic equipment. A resistance band and a step are enough.

Balance Training Adds a Layer That Strengthening Alone Misses

Overpronation is not just a strength problem. It is also a coordination problem. Your foot needs to sense the ground and react to shifting loads in real time, and that feedback loop depends on proprioception. Balance exercises train this feedback loop, and the research suggests they add benefits beyond what strengthening alone provides. A randomized trial found that combining short foot exercises with balance training on unstable surfaces improved both static and dynamic balance significantly more than balance training alone in people with flat feet.¹³

Interestingly, plyometric exercises like jump landings and hopping drills may outperform traditional short foot exercises for reducing navicular drop and improving dynamic balance. One trial that compared six weeks of plyometric training against short foot exercises with balance training found that the plyometrics group achieved greater reductions in navicular drop and better Y-Balance Test scores across all three reach directions.¹⁴ This makes sense: plyometrics force the foot muscles to stiffen the arch rapidly under high loads, which is closer to what they actually need to do during running or sports. If your overpronation mainly shows up during athletic activity, incorporating controlled jumping and landing drills into your program is worth considering.

Orthotics and Shoe Selection

Foot orthotics work by repositioning the foot inside the shoe, redistributing pressure away from the collapsed arch and providing external support where the muscles are not doing their job. A common question is whether you need expensive custom orthotics or whether a good off-the-shelf pair will do. Research comparing contoured prefabricated orthotics to contoured custom-made orthotics found similar changes in plantar loading between the two, with no statistically significant difference in most variables.¹⁵ For most people with moderate overpronation, a well-made prefabricated insole with good medial arch support is a reasonable first option before spending several hundred dollars on custom devices.

Shoe choice matters too. Motion control shoes, the stiff, heavy category marketed to overpronators, reduce peak rearfoot eversion and knee internal rotation during running.¹⁶ Whether you need a full motion control shoe or a moderate stability shoe depends on the severity of your pronation and whether you are experiencing symptoms. If your pronation is mild and pain-free, stability shoes with a firm medial post may be all you need. If your ankles visibly collapse during running and you have recurring injuries, a motion control shoe or an orthotic-shoe combination is a more aggressive but appropriate choice.

One important caveat: orthotics and supportive shoes are tools, not cures. They manage the symptom by externally controlling motion, but they do not strengthen the muscles that should be controlling the motion internally. The best outcomes come from using orthotics to reduce pain and symptoms while simultaneously working on the strengthening and mobility exercises that address the underlying weakness.

The Case for Less Shoe, Not More

Minimalist footwear seems counterintuitive for someone whose arches collapse, but there is a growing body of evidence that wearing less shoe forces the foot to work harder and may strengthen it over time. A cross-sectional study comparing people who habitually wore minimal shoes to those in conventional footwear found that the minimal-shoe group had arches roughly 9% higher and arch stiffness about 27% greater. The intrinsic foot muscles, particularly the abductor hallucis, were also significantly larger in the minimally shod group.¹⁷

A six-month intervention study found that transitioning to minimal footwear during daily activities increased foot strength, though arch height changes took longer than six months to become significant.¹⁸ And a study of runners who switched to minimalist shoes found significant increases in the size of specific intrinsic foot muscles and a 60% increase in arch stiffness.¹⁹

The key here is transition speed. Suddenly going from a cushioned, supportive shoe to a paper-thin sole while running your usual mileage is a recipe for stress fractures and Achilles tendon problems. If you want to experiment with minimalist footwear, start by wearing it only for short walks and gradually increase the time and intensity over months. Think of it as a training stimulus for the foot, not a permanent replacement for all your shoes from day one.

Gait Retraining Can Change How Your Foot Hits the Ground

Strengthening gives the muscles the capacity to support the arch. Gait retraining teaches your nervous system to actually use that capacity while moving. The approach typically involves running on a treadmill with real-time visual feedback, where you can see a measure of your foot position on a screen and try to keep it within a target range. A gait retraining program using visual biofeedback reduced rearfoot plantar pressure and foot pronation in recreational runners, with the improvements persisting after the intervention ended.²⁰

One specific technique is toe-in running, where you deliberately point your feet slightly inward compared to your normal foot angle. A systematic review and meta-analysis found that toe-in running with visual feedback reduced peak rearfoot eversion, peak pronation, and arch collapse, while also increasing internal arch height.²¹ The evidence for gait retraining is still relatively young, but it is one of the few interventions that directly targets the dynamic pattern of how you pronate rather than just building the muscles or bracing against the motion.

You do not necessarily need a lab with pressure sensors to experiment with gait retraining. Even using a mirror at the gym to watch your knees and ankles during single-leg squats or step-downs gives you visual feedback on whether your arch is collapsing. Training yourself to feel what a well-controlled arch position feels like during loading is valuable practice that carries over to walking and running.

The Kinetic Chain Problem

Your foot does not exist in isolation. When your ankle rolls in, it drags the shin bone into internal rotation, which can push the knee inward into a position called dynamic knee valgus, the knock-kneed look you see during squats or landings. This chain of events can be driven from the bottom up, where the foot and ankle cause the knee to collapse, or from the top down, where weak hip muscles allow the thigh to rotate inward and the knee to follow.²² In many people, both directions are at play simultaneously.

This has practical implications for your exercise program. If your overpronation is partly driven by hip weakness, foot exercises alone will not fully solve the problem. Adding hip abductor and external rotator strengthening, things like clamshells, side-lying leg raises, and single-leg glute bridges, addresses the top-down contribution. A complete approach works on both ends of the chain: strong hips control the thigh, strong foot and ankle muscles control the arch, and the knee in between benefits from both.

Injuries That Overpronation Feeds Into

Overpronation is not just a mechanical quirk. It is a risk factor for several common injuries, which is often what motivates people to address it in the first place.

• Shin splints: Excessive pronation increases strain on the posterior tibial tendon and creates abnormal traction forces along the inner shin, contributing to medial tibial stress syndrome.²³
• Plantar fasciitis: When the arch flattens excessively, it stretches the plantar fascia beyond its normal range during every step, creating excessive tensile forces that can lead to chronic heel pain.²⁴ People with plantar fasciitis show greater total rearfoot eversion during walking compared to healthy controls.²⁵
• Posterior tibial tendon breakdown: The tendon that works hardest to resist pronation is also the one most damaged by it. Chronic overloading leads to degeneration, which causes more pronation, which causes more damage, in a self-reinforcing cycle that can eventually require surgical repair.³

Addressing overpronation early is one of the more effective ways to reduce the risk of these problems, particularly for runners and people who spend long hours on their feet. By the time pain appears, the cycle has often been running for months or years.

When Conservative Measures Are Not Enough

Most people with overpronation will get meaningful improvement from the combination of exercises, footwear changes, and orthotics described above. But some cases, particularly advanced posterior tibial tendon dysfunction or rigid flatfoot deformity, do not respond adequately to conservative treatment. Surgery becomes a consideration when the foot has become structurally deformed and pain persists despite months of rehab.

One of the less invasive surgical options is subtalar arthroereisis, where a small implant is placed in the sinus tarsi, a natural space between the ankle bone and the heel bone, to limit the excessive inward roll. It has been described as a minimally invasive, effective, and low-risk procedure for flexible flatfoot in both children and adults, and can be used alone or in combination with other corrections.²⁶ A comparative study found that combining this implant with a calcaneal osteotomy (a procedure that shifts the heel bone) produced the greatest radiological correction and restored a normal gait pattern on pressure analysis.²⁷

For severe adolescent flatfoot, more aggressive reconstructions combine calcaneal lengthening osteotomy with subtalar arthroereisis, producing dramatic improvements in alignment and functional scores.²⁸ These are real surgeries with real recovery times, though, and they are reserved for cases where the deformity is significant and the person has not responded to non-surgical treatment. The vast majority of people with overpronation will never need to think about surgery.

Children, Adults, and the Flatfoot That Never Left

Flat feet are nearly universal in toddlers because the arch has not yet developed. In most children, the arch forms naturally by around age six to eight. But in a meaningful number of people, it never fully develops, and their adult flatfoot is really a leftover from childhood. Other adults develop flatfoot later in life through tendon degeneration, weight gain, or chronic overuse. The distinction matters because childhood-onset flexible flatfoot tends to be painless and often does not need intervention unless it causes symptoms, while adult-acquired flatfoot from posterior tibial tendon problems is progressive and benefits from early treatment.

If you are an adult who has always had flat feet and has never had pain, aggressive intervention may not be necessary. But if you have recently noticed your arches dropping, or if one foot is flatter than the other, or if you are developing pain along the inner ankle, those are signs that something is actively changing and worth investigating before it gets worse.

Smart Insoles and Pressure Mapping

An emerging technology that may become more relevant over the next few years is pressure-sensing insoles that map how forces distribute across your foot during daily life. These devices use arrays of pressure sensors to track loading patterns in real time, and some incorporate machine learning to identify abnormal pressure signatures that correlate with specific foot problems.²⁹ For overpronation, this could eventually mean getting objective feedback on whether your arch is collapsing during actual daily activity, not just during a brief clinic visit. The technology is still mostly in research stages, but consumer-grade versions are beginning to appear, and they could become a useful self-monitoring tool for people actively working on their foot mechanics.
