If you have flat feet, you may have wondered: Can insoles actually help, or are they just another temporary solution?
The short answer is yes, insoles can help some people with flat feet. Depending on the design and the individual, insoles may provide external support, influence foot mechanics, redistribute pressure and potentially improve pain or comfort.
However, insoles do not work the same way for everyone, and using an insole does not automatically mean that the underlying structure of a flat foot has been permanently changed.
Research provides some support for using foot orthoses as part of conservative flat-foot management. A 2024 systematic review and meta-analysis found that foot orthoses changed several measures of rearfoot, ankle and knee mechanics during walking in adults with flexible flat feet.
A more recent 2026 systematic review and meta-analysis of randomized trials also found improvements in pain and several biomechanical or radiographic outcomes with insole interventions, although the included participants ranged from children to young adults, so the findings should not automatically be generalized to every adult with flat feet.
So, are insoles good for flat feet? They can be useful for the right person and the right purpose. The important question is what you want the insole to accomplish.
Insoles can help some people with flat feet by providing external support and influencing how the foot interacts with the ground during standing and movement. They may also help reduce pain or improve comfort in some cases.
But an insole is not a universal treatment for flat feet.
Its effectiveness can depend on:
Whether your flat feet are flexible or rigid
Whether you have symptoms
The cause of your flat feet
Your activity level
Your footwear
The shape and firmness of the insole
How well the insole fits your foot and shoe
Whether another condition is contributing to your symptoms
This is why “insoles for flat feet” should not automatically mean “the same insole for everyone.”
An insole creates an additional interface between your foot and the shoe.
Depending on its construction, it may:
Support the arch
Influence rearfoot motion
Change plantar pressure distribution
Influence foot and ankle mechanics
Alter how the foot interacts with the ground
Provide cushioning
Improve perceived comfort
Potentially reduce symptoms in some people
The important distinction is that these are primarily supportive and functional effects.
They are not necessarily the same as permanently changing the anatomical structure of the foot.
For more detail on the difference between support and structural correction, see Can Arch Support Correct Flat Feet? What It Can and Can't Do.
1. They can provide additional arch support
Some insoles are designed with a raised area under the medial side of the foot.
This can provide an additional support surface for someone with a low or flattened arch.
However, the objective isn't necessarily to push the arch as high as possible.
More arch support does not automatically mean better support.
The shape, height, firmness and position of the support need to work with the individual's foot.
2. They can influence foot mechanics
Foot orthoses can change the way the foot and lower limb move during walking.
A 2024 systematic review and meta-analysis involving adults with flexible flat feet found significant effects of foot orthoses on several measures, including peak rearfoot eversion, ankle dorsiflexion, ankle eversion and selected ankle and knee moments.
This means an insole isn't simply a piece of cushioning.
Its geometry can influence how your foot interacts with the ground.
3. They can redistribute pressure
An insole changes the contact surface beneath the foot.
Depending on its design, it can alter where and how pressure is distributed during standing or walking.
This may be relevant if you experience discomfort in particular areas of the foot.
However, pressure redistribution is not automatically beneficial in every situation. A design that works for one foot may feel uncomfortable on another.
4. They may improve comfort
Comfort is one of the most practical reasons people try insoles.
Research involving people with flexible flat feet has found evidence of potential pain reduction with orthoses, although study designs and interventions vary.
A systematic review and meta-analysis published in 2023 found a statistically significant greater reduction in pain in adults using orthoses compared with controls, but the authors concluded that the overall evidence was too heterogeneous to establish a universal benefit.
So the evidence supports potential benefit, not a guarantee.
5. They can provide support during walking and standing
People who spend long periods walking or standing may use insoles to make their footwear feel more supportive.
This can be particularly relevant if flat feet are associated with:
Foot fatigue
Aching
Discomfort after prolonged standing
Discomfort during walking
A feeling of inadequate support
The goal should be improved comfort and function rather than trying to force every flat foot into a particular shape.
Research suggests that insoles can have measurable effects in people with flat feet, but their effectiveness varies according to the outcome being measured and the type of intervention.
This is an important distinction.
An insole may demonstrate an effect on:
Pain
Foot mechanics
Joint loading
Pressure distribution
Certain radiographic measures
Comfort
without necessarily producing the same effect on every outcome.
A 2024 meta-analysis found measurable biomechanical changes with foot orthoses during walking in adults with flexible flat feet.
A 2026 network meta-analysis of randomized controlled trials found significant pain reductions with both insole-only and insole-plus-exercise interventions. It also reported improvements in selected measures such as calcaneal pitch and center-of-pressure displacement. However, the participants ranged from children to young adults, which limits how directly the results can be applied to every adult population.
Earlier research has been more cautious. A systematic review focused specifically on adults with flat feet found that the evidence for foot orthoses was inconsistent and called for better-quality research.
The overall picture is therefore:
Insoles can work, but their effect is not universal, and “work” does not necessarily mean permanently correcting flat feet.
They may.
Pain reduction is one of the better-supported potential benefits of orthotic intervention.
A meta-analysis of patient-reported outcomes found that adults using foot orthoses had a greater reduction in pain than control groups, although the authors emphasized the heterogeneity of the evidence.
Another network meta-analysis found that both foot orthoses and exercise interventions reduced pain in adults with flat feet, with active interventions such as exercise performing better than passive interventions in that analysis.
This suggests that if your goal is to manage flat-foot-related discomfort, an insole may be one part of a broader approach rather than necessarily the entire solution.
This depends on what you mean by “improve.”
If improvement means less pain:
Possibly, yes.
If improvement means greater comfort:
Possibly, yes.
If improvement means different foot mechanics:
Yes, research has demonstrated biomechanical changes with some orthoses.
If improvement means permanently rebuilding the arch:
That is a much stronger claim and should not automatically be inferred from using an insole.
For a detailed explanation, read Can Arch Support Correct Flat Feet?.
They can potentially help when the pain is associated with the way the foot is functioning during weight-bearing activity.
But flat feet and foot pain are not synonymous.
Some people have flat feet without any pain.
Others may have pain caused by another condition that happens to coexist with flat feet.
Possible contributors to foot pain can include:
Plantar heel pain
Tendon problems
Joint problems
Overuse
Poorly fitting footwear
Previous injury
Nerve-related problems
Other musculoskeletal conditions
Therefore, an insole shouldn't be treated as a diagnostic tool.
If pain is persistent or worsening, identifying the cause is more important than simply increasing arch support.
They may.
Foot orthoses have been shown to influence lower-limb mechanics during walking in adults with flexible flat feet. The 2024 meta-analysis found changes in rearfoot, ankle and knee-related biomechanical measures.
For someone who experiences discomfort while walking, the practical question is:
Does the insole make walking more comfortable and manageable without creating new discomfort?
That is often more useful than asking whether an insole is “correcting” the foot.
They may improve perceived support or comfort during prolonged standing for some people.
Standing places continuous load through the feet, and an insole can change the contact surface and pressure distribution.
However, there is no guarantee that an insole will make prolonged standing comfortable for every person with flat feet.
If standing consistently causes pain, particularly if the pain is increasing, consider whether another condition is contributing.
Insoles can influence foot and lower-limb alignment and mechanics while they are being worn.
This is supported by biomechanical research.
The 2024 meta-analysis found significant effects of foot orthoses on rearfoot eversion, ankle motion and selected ankle and knee moments during walking in adults with flexible flat feet.
However, this should not be interpreted as proof that an insole permanently realigns the foot.
An external orthosis and permanent anatomical correction are two different concepts.
Insoles can change how load is distributed beneath the foot.
But reducing pressure everywhere is not necessarily the goal.
A well-designed insole may redistribute pressure from one region to another rather than simply eliminating pressure.
The result can depend on:
Insole geometry
Material
Arch shape
Heel structure
Foot shape
Shoe design
Body weight
Walking pattern
This is one reason why an insole that feels excellent to one person can feel uncomfortable to another.
They can be useful for some people with flat feet.
An arch-support insole provides additional support beneath the medial side of the foot and can influence foot mechanics.
However, the highest or firmest arch is not automatically the best arch support.
The goal is appropriate support rather than maximum pressure.
If you're trying to understand the role of arch support specifically, see:
How Does Arch Support Help Flat Feet?
And if you're trying to determine whether you actually need arch support:
Do Flat Feet Need Arch Support?
There is no single insole specification that is ideal for everyone with flat feet.
When evaluating an insole, consider:
Arch shape
The contour should correspond reasonably well with your foot rather than creating a painful pressure point.
Firmness
The support should provide the intended function without feeling excessively hard or intrusive.
Cushioning
Some people benefit from additional cushioning, particularly when comfort is the main objective.
Heel support
The rearfoot section can influence how the foot sits within the shoe.
Thickness
An insole that is too thick can reduce the space available inside the shoe and affect fit.
Shoe compatibility
An insole must work with the shoe.
A supportive insole in a poorly fitting shoe may still be uncomfortable.
Your activity
The requirements of an insole used for everyday walking may differ from those of an insole used for running or prolonged standing.
There is no universal answer.
A very soft insole may feel comfortable initially but may not provide the type of structural support someone is looking for.
A very firm insole may provide a stronger support sensation but can also feel uncomfortable if the contour does not match the foot.
The better question is:
Does the insole provide an appropriate balance of support, pressure distribution and comfort for your foot and activity?
They can cause discomfort if they are poorly fitted or inappropriate for the individual, but discomfort does not necessarily mean that the insole is damaging the foot.
Potential problems include:
Excessive pressure under the arch
Heel discomfort
Changes in how the shoe fits
Friction
Blisters
Increased discomfort during activity
If an insole consistently causes pain, numbness or other concerning symptoms, stop using it and consider getting professional advice.
An insole should generally feel supportive rather than aggressively intrusive.
There is no single adaptation period that applies to everyone.
A practical approach is to introduce a new insole gradually rather than immediately wearing it for an entire day of demanding activity.
Pay attention to:
Arch pressure
Heel comfort
Foot fatigue
Skin irritation
Changes in walking comfort
Any new or worsening pain
If discomfort persists rather than improving with adaptation, the issue may be the fit, design or suitability of the insole.
Some people can use suitable insoles every day.
The important consideration is whether the insole is comfortable, appropriately fitted and compatible with the footwear.
Daily use does not mean you need the same insole in every shoe.
For example, an insole may fit well in a roomy walking shoe but not work well in a low-volume formal shoe.
No.
Having flat feet does not automatically mean you need an insole.
Some people have flat feet without pain, functional limitations or difficulty with everyday activities.
In such cases, an insole may be optional rather than necessary.
If you experience symptoms, however, an insole can be one potential conservative-management option.
For more information, see Do Flat Feet Need Arch Support?
Insoles may be worth considering if you experience:
Foot discomfort during walking
Foot fatigue after standing
Discomfort during prolonged activity
A feeling that your footwear lacks support
Symptoms associated with flexible flat feet
A need for additional support during a particular activity
They may also be considered as part of a broader conservative-management program.
However, the presence of flat feet alone does not establish that an insole is required.
Insoles and exercise serve different purposes.
Insoles
An insole provides external support.
It can influence the interaction between the foot and the ground and may alter certain biomechanical measures.
Exercise
Exercise targets active function, such as strength, mobility and movement control.
Evidence comparing approaches suggests that exercise can be an important component of flat-foot management. A network meta-analysis found that both exercise and orthoses reduced pain, while active interventions performed better than passive interventions for pain in that analysis.
This means you don't necessarily have to choose between the two.
Depending on your situation, appropriate footwear + insoles + exercise may address different aspects of the problem.
This is not a simple either-or question.
Barefoot walking and wearing an insole represent very different mechanical environments.
Whether barefoot activity is appropriate depends on:
Your symptoms
The surface
Activity intensity
Foot strength
Footwear habits
Underlying condition
There is not enough evidence to claim that everyone with flat feet should either use insoles or avoid them.
The appropriate choice depends on the individual's goals and tolerance.
Insoles can support flat feet and influence their mechanics, but “correct” can imply permanent structural change.
A previous network meta-analysis of adult flat-foot studies found that both exercise and orthoses reduced pain, but the interventions did not demonstrate a corresponding realignment of foot posture as measured by navicular drop.
More recent evidence has identified improvements in some biomechanical and radiographic measures with insole interventions, but these findings should not be interpreted as evidence that every insole permanently rebuilds the adult arch.
For the full discussion:
Can Arch Support Correct Flat Feet? What It Can and Can't Do
Not necessarily for every person.
Custom orthoses can be designed around an individual's foot characteristics, but “custom” does not automatically mean “better” for every outcome.
A systematic review of insole types for musculoskeletal conditions highlighted the need for better assessment methods before prescribing particular insoles.
The appropriate choice depends on:
Foot structure
Symptoms
Activity
Footwear
Clinical findings
Insole design
For mild, uncomplicated support needs, a suitable prefabricated insole may be sufficient for some people.
For complex or persistent problems, professional assessment may be more appropriate.
Children are a different population from adults.
Foot development changes with age, and a flat-looking foot in childhood does not necessarily represent the same condition as symptomatic adult flatfoot.
The recent 2026 meta-analysis included participants from childhood through young adulthood, but its findings should not be generalized to all ages without considering developmental differences.
Parents should seek professional assessment when a child's flat feet are painful, asymmetric, rigid or associated with functional difficulties.
Consider professional assessment if you have:
Persistent foot pain
A newly developed flat foot
One foot that is becoming flatter than the other
Swelling
Weakness
Difficulty walking
Increasing difficulty standing
Significant changes in foot shape
Numbness or tingling
Pain that persists despite changing footwear or activity
An assessment can help determine whether you simply have an asymptomatic low arch or whether another condition is contributing to your symptoms.
The research is increasingly informative, but it is not a reason to make universal claims.
A 2024 systematic review and meta-analysis found that foot orthoses produced significant changes in several lower-limb biomechanical measures in adults with flexible flat feet.
A 2023 systematic review and meta-analysis found that orthoses may reduce pain in adults with symptomatic flexible flat feet, although the authors considered the overall evidence heterogeneous.
A 2026 network meta-analysis found significant pain reductions with insole interventions and improvements in selected biomechanical and radiographic outcomes. However, the participant age range was broad, so the results should be interpreted according to the population being considered.
A 2025 meta-analysis in runners with asymptomatic flat feet found that orthoses with specific medial posting produced some changes in ankle and Achilles-loading measures, while arch-support-only orthoses did not significantly change the primary outcomes studied. The authors also emphasized that more research is needed.
Evidence on balance is also mixed. A 2024 systematic review found inconsistent effects depending on the orthosis design and study protocol.
What does this mean in practical terms?
The evidence supports a measured conclusion:
Insoles can be a useful conservative-management tool for some people with flat feet, particularly when the goal is symptom management or changing foot mechanics. But there is no single insole that works for everyone, and using an insole should not automatically be equated with permanently correcting flat feet.
Can insoles help flat feet? Yes, they can help some people, particularly with support, comfort, pain management and foot mechanics.
Insoles provide external support rather than automatically changing the underlying structure of the foot.
Research shows that foot orthoses can influence several foot and lower-limb biomechanical measures.
Some evidence suggests orthoses can reduce pain in adults with symptomatic flexible flat feet.
Newer research supports potential benefits from insole interventions for pain and selected biomechanical outcomes, but study populations and designs vary.
More arch support is not necessarily better.
The right insole depends on foot shape, symptoms, footwear and activity.
Insoles and exercises can address different aspects of flat-foot management.
Not everyone with flat feet needs an insole.
Persistent, worsening, asymmetric or newly developed flat feet should be assessed by an appropriate healthcare professional.
