Flat Feet and Lower Limb Pain: Can Your Feet Cause Knee, Hip or Leg Pain?

Flat Feet and Lower Limb Pain: Can Your Feet Cause Knee, Hip or Leg Pain?

If you have flat feet, you may have been told that they are the reason your knees, hips or lower back hurt.

But is that actually true?

The answer is more complicated than “flat feet are bad.”

Some people have completely flat feet and never experience pain. Others develop foot, ankle, knee or hip symptoms that may be influenced by the way their feet move and how their body handles load.

The important question isn’t simply:

“Do I have flat feet?”

It’s:

“Are my foot mechanics contributing to my symptoms?”

At Restorative Touch Physiotherapy on Hamilton Mountain, we assess how your foot, ankle, knee and hip work together rather than assuming that your foot shape is automatically the cause of your pain.

This guide explains what flat feet are, how they may influence the rest of the lower limb, when they matter, whether exercises can help, and when orthotics might be worth considering.

What Are Flat Feet?

Flat feet, also called pes planus, occur when the arch along the inside of the foot is lower than usual or appears to flatten when you stand.

Everyone’s feet are different.

Some people naturally have:

• High arches
• Moderate arches
• Low arches
• Flexible arches
• Rigid arches

Having a low arch doesn’t automatically mean something is wrong.

In fact, many people with flat feet have no symptoms whatsoever.

Why Do Some People Have Flat Feet?

Flat feet can be completely normal and may be influenced by genetics, age and the development of the foot.

Other factors can contribute to changes in the arch, including:

• Previous injuries
• Changes in body weight
• Pregnancy
• Tendon problems
• Arthritis
• Changes in activity
• Age-related changes

Some people have had flat feet their entire lives.

Others notice that their arch has gradually become flatter.

A newly developing or rapidly changing flat foot—particularly if it is painful—deserves an assessment.

Are Flat Feet Bad?

No.

This is one of the biggest misconceptions about foot mechanics.

A flat foot isn’t automatically a damaged foot.

Your feet are designed to move.

The arch naturally changes shape as you walk, run and stand.

The problem isn’t necessarily that your foot pronates or that your arch lowers.

The question is whether your foot is tolerating the demands you’re placing on it.

For example, a person who walks 30 minutes per day may have no symptoms despite having flat feet.

That same person may develop pain after suddenly starting a running program.

The issue may be the rapid increase in load rather than the shape of their foot.

What Is Pronation?

Pronation is a normal movement of the foot.

During walking and running, the foot changes position as it accepts and transfers load.

When people talk about “overpronation,” they are usually referring to a greater amount or duration of pronation.

But pronation itself isn’t inherently harmful.

Your body is remarkably adaptable.

The amount of pronation that is normal for one person may look different from another person’s.

Can Flat Feet Cause Knee Pain?

They can potentially contribute to knee symptoms in some people, but flat feet aren’t automatically the cause.

The foot and knee are connected through the entire lower limb.

Changes in foot movement can influence how the tibia and knee move.

However, knee pain is influenced by many factors, including:

• Muscle strength
• Activity level
• Training load
• Previous injury
• Body weight
• Hip strength
• Knee movement
• Recovery
• Sleep
• Overall physical capacity

So if you have flat feet and knee pain, it doesn’t automatically mean:

“Your arches need to be corrected.”

Instead, we need to determine whether your foot mechanics are actually relevant to your symptoms.

Can Flat Feet Cause Hip Pain?

Potentially, but again, the relationship isn’t that simple.

Your foot, ankle, knee and hip function as a kinetic chain.

Changes at one joint can influence movement elsewhere.

However, hip pain can have many causes.

Your physiotherapist may assess:

• Hip strength
• Hip mobility
• Walking mechanics
• Running mechanics
• Single-leg control
• Foot and ankle movement
• Training load

If your feet are contributing to the problem, they can be addressed as part of the overall treatment plan.

Can Flat Feet Cause Shin Pain?

Foot mechanics may play a role in some lower-leg problems, particularly when combined with increased activity.

For example, someone who suddenly increases their running mileage may develop shin pain.

Their foot mechanics may be one factor.

But other factors could include:

• Training volume
• Running frequency
• Surface
• Recovery
• Strength
• Previous injury
• Calf capacity

Treating only the foot may therefore miss the bigger picture.

Can Flat Feet Cause Plantar Fasciitis?

Flat feet can be one factor associated with plantar heel pain, but they aren’t necessarily the sole cause.

Plantar fasciitis—or more accurately, plantar heel pain—is often influenced by the amount of load placed on the plantar tissues.

Common triggers include:

• Increasing running
• Increasing walking
• Standing for long periods
• Changes in footwear
• Increased body weight
• Reduced calf capacity
• Changes in activity

If you have flat feet and plantar heel pain, treatment should focus on your symptoms and your ability to tolerate load—not simply on trying to create a higher arch.

Can Flat Feet Cause Ankle Pain?

Flat feet can sometimes be associated with increased stress around the ankle and foot.

This may be particularly relevant if you also have:

• Ankle instability
• Previous ankle sprains
• Tendon pain
• Arthritis
• Significant changes in foot structure

However, ankle pain can occur for many reasons.

A proper assessment can determine whether your foot mechanics are relevant.

Can Flat Feet Cause Lower Back Pain?

This is one of the most common claims you’ll see online.

The reality is more nuanced.

Your feet influence the way you interact with the ground, and lower-limb movement can influence movement throughout the body.

But there is no simple rule that says:

flat feet = lower back pain.

Back pain is complex and can be influenced by:

• Strength
• Activity
• Work demands
• Sleep
• Stress
• Previous injury
• Physical conditioning
• Sensitivity of the nervous system

If you have flat feet and back pain, your feet may be worth considering—but they shouldn’t automatically be blamed.

How Do I Know If My Flat Feet Are Causing My Pain?

This is the most important question.

You can’t determine it simply by looking at your feet.

A physiotherapy assessment may include:

Standing assessment

Your physiotherapist may look at your foot and arch while you’re standing.

Walking assessment

They may assess how your foot moves while walking.

Single-leg movements

Tasks such as a single-leg squat or step-down can show how your foot, knee and hip work together.

Strength testing

Your calf, foot, ankle, knee and hip strength may all be assessed.

Mobility assessment

Your ankle and foot mobility can influence how your lower limb handles load.

Functional testing

If you’re a runner or athlete, your assessment may include sport-specific movements.

The goal is to determine whether there is a meaningful connection between your foot mechanics and your symptoms.

What Is a Flexible Flat Foot?

A flexible flat foot means that the arch appears flattened when you’re standing but can reappear when the foot isn’t bearing weight or when you change how you’re loading it.

Flexible flat feet are common and aren’t necessarily problematic.

Many people with flexible flat feet participate in:

• Running
• Soccer
• Basketball
• Weightlifting
• Hiking
• Other sports

without experiencing symptoms.

What Is a Rigid Flat Foot?

A rigid flat foot doesn’t change shape as easily.

A rigid or newly developing flat foot, especially when accompanied by pain, stiffness or difficulty walking, may warrant further assessment.

This can sometimes be associated with structural changes or conditions affecting the bones, joints or tendons of the foot.

Can You Fix Flat Feet?

This depends on what you mean by “fix.”

You generally can’t completely change the underlying bone structure of your foot through exercises.

But you may be able to improve:

• Foot strength
• Calf strength
• Balance
• Lower-limb control
• Tolerance to walking or running
• Symptoms

And those things may matter much more than whether your arch looks perfectly curved.

The goal of physiotherapy isn’t necessarily to create a textbook-looking arch.

It’s to help your foot become strong, comfortable and capable.

Exercises for Flat Feet

Exercises can help improve foot and lower-limb strength and control.

They aren’t designed to magically rebuild your arch overnight.

Here are some examples.

Exercise 1: Short Foot Exercise

Sit or stand with your foot flat on the ground.

Without curling your toes, gently draw the ball of your foot toward your heel to create a subtle shortening of the foot.

Hold for approximately 5–10 seconds.

Relax.

Repeat 8–12 times.

Important: Don’t aggressively claw your toes into the floor.

The goal is controlled foot activation.

Exercise 2: Calf Raises

Stand with your feet approximately hip-width apart.

Slowly rise onto your toes.

Pause at the top.

Lower yourself slowly.

Start with:

2–3 sets of 10–15 repetitions.

As you become stronger, progress to single-leg calf raises.

Your calf muscles play an important role in walking, running and absorbing and producing force.

Exercise 3: Single-Leg Balance

Stand on one leg.

Maintain your balance for 20–30 seconds.

Progress by:

• Closing your eyes
• Standing on a less stable surface
• Reaching with the opposite leg
• Performing a small squat

Start with:

3 × 20–30 seconds per side.

Exercise 4: Step-Down

Stand on a low step.

Slowly lower one heel toward the floor.

Keep your knee controlled over your foot.

Return to the starting position.

Try:

2–3 sets of 8–12 repetitions.

This exercise challenges the entire lower limb rather than just the foot.

Exercise 5: Single-Leg Calf Raise

Stand on one foot with something nearby for balance.

Rise onto your toes.

Pause.

Slowly lower.

Try:

2–3 sets of 8–15 repetitions.

Progress the exercise as your strength improves.

Do Foot Exercises Actually Raise Your Arch?

They may improve your ability to actively control the foot, but exercise isn’t guaranteed to permanently change the shape of your arch.

That’s okay.

A stronger foot doesn’t need to look dramatically different.

What matters is whether it can handle the demands you’re placing on it.

If your goal is to run, hike or play soccer without pain, improving your ability to tolerate those activities is more important than achieving a particular-looking arch.

Should I Wear Orthotics for Flat Feet?

Sometimes.

Orthotics can be helpful for certain people, particularly when foot mechanics appear to contribute to their symptoms.

But having flat feet doesn’t automatically mean you need orthotics.

This is important because many people are sold orthotics simply because someone observes that their arches are low.

A better question is:

“What problem are the orthotics solving?”

What Do Orthotics Actually Do?

Orthotics can alter how forces are distributed through the foot and lower limb.

They may help:

• Reduce symptoms
• Improve comfort
• Modify load
• Support a return to activity
• Make certain footwear more comfortable

They aren’t necessarily designed to permanently “correct” your feet.

And you don’t necessarily need to wear them forever.

Custom Orthotics vs Store-Bought Orthotics

There isn’t a universal winner.

Some people do well with an over-the-counter insert.

Others may benefit from a customized orthotic.

The choice depends on:

• Your symptoms
• Foot shape
• Footwear
• Activity
• Previous injuries
• Your response to treatment

If a less expensive option works, there’s often no reason to spend significantly more.

Do I Need Custom Orthotics If I Have Flat Feet?

Not necessarily.

If you’re pain-free, you generally don’t need orthotics simply because someone tells you your arches are low.

If you’re experiencing pain, an assessment can help determine whether an orthotic is likely to provide meaningful benefit.

Can Orthotics Make Your Feet Weaker?

This is another common concern.

Wearing orthotics doesn’t automatically make your feet weak.

However, orthotics shouldn’t necessarily be your only strategy.

If your foot is painful or lacking capacity, you may benefit from both:

external support + progressive strengthening.

As your capacity improves, your reliance on external support may change.

How Long Should You Wear Orthotics?

That depends on why you’re using them.

Some people use orthotics primarily for activities that provoke symptoms.

Others wear them most of the day.

If you’re new to orthotics, gradually increasing your wear time can help your body adapt.

Your clinician can give you more specific instructions based on the type of orthotic and your symptoms.

What Shoes Are Best for Flat Feet?

There isn’t one universally “best” shoe for flat feet.

The best shoe is generally one that:

• Fits comfortably
• Doesn’t cause pain
• Works for your activity
• Provides an appropriate level of support for you

For some people, a more supportive shoe feels better.

For others, a neutral shoe works perfectly well.

Shoe choice should be based on comfort and function, not simply the appearance of your arch.

Do Flat Feet Prevent You From Running?

Absolutely not.

Many runners have flat feet.

Having flat feet does not mean you need to avoid running.

If running causes pain, the more important questions are:

• How much are you running?
• How quickly did you increase your mileage?
• How strong are your calves and legs?
• How well are you recovering?
• What surfaces are you running on?
• What does your running program look like?

Your feet can often adapt to running when the workload is increased appropriately.

Flat Feet and Running Injuries

If you’re a runner with flat feet and recurring injuries, it may be worthwhile to have your entire lower limb assessed.

Your physiotherapist may look at:

• Foot mechanics
• Ankle mobility
• Calf strength
• Knee control
• Hip strength
• Running mechanics
• Training volume

The goal isn’t to find something “wrong” with you.

It’s to identify factors that may be modifiable.

Flat Feet in Children

Flat feet are extremely common in children.

A child’s arch develops over time, and a low arch does not automatically mean they need treatment.

However, an assessment may be appropriate if a child has:

• Persistent foot pain
• Difficulty participating in activities
• Significant stiffness
• A noticeable change in foot shape
• Difficulty walking or running
• Symptoms that are affecting their quality of life

Parents shouldn’t feel that every flat foot needs to be “corrected.”

When Should You Be Concerned About Flat Feet?

You should consider an assessment if:

• Your feet are painful.
• Your arch has recently changed.
• One foot is significantly flatter than the other.
• You have difficulty walking.
• You have recurring ankle injuries.
• You have persistent plantar heel pain.
• Your knees hurt during walking or running.
• You’re developing unexplained lower-limb pain.
• Your symptoms are limiting sport or exercise.

A new, painful flat foot deserves particular attention.

Can Physiotherapy Help Flat Feet?

Yes.

Physiotherapy can help determine whether your foot mechanics are contributing to your symptoms and develop a treatment plan around your goals.

Treatment may include:

• Foot strengthening
• Calf strengthening
• Balance exercises
• Ankle mobility
• Hip and knee strengthening
• Gait retraining when appropriate
• Running assessment
• Activity modification
• Orthotic recommendations

The goal isn’t necessarily to “fix” the appearance of your feet.

It’s to improve how your entire lower limb functions.

A Better Way to Think About Flat Feet

Instead of asking:

“Are my flat feet causing my pain?”

Try asking:

“Are my feet strong enough and capable enough for what I’m asking them to do?”

That question is much more useful.

A flat foot that can comfortably handle 10,000 steps per day isn’t necessarily a problem.

A painful foot that struggles with 2,000 steps may need attention—even if it looks completely normal.

Your body’s capacity matters more than whether your anatomy looks perfect.

Frequently Asked Questions About Flat Feet

Are flat feet bad?

No. Flat feet are common and many people with flat feet have no symptoms.

Can flat feet cause knee pain?

They may contribute to knee symptoms in some people, but knee pain has many possible causes. An assessment can determine whether foot mechanics are relevant.

Can flat feet cause hip pain?

Potentially, but there isn’t a simple flat-feet-to-hip-pain relationship. Other factors such as hip strength, activity and previous injuries also matter.

Can flat feet cause plantar fasciitis?

Flat feet may be one contributing factor, but plantar heel pain is usually influenced by multiple factors, particularly how much load the foot is handling.

Can flat feet cause back pain?

There isn’t a simple rule that flat feet cause back pain. Lower-limb mechanics may contribute in some individuals, but back pain is influenced by many factors.

Can exercises fix flat feet?

Exercises can improve foot and lower-limb strength and control, but they aren’t guaranteed to permanently change the underlying structure of your arch.

Do I need orthotics for flat feet?

Not necessarily. Orthotics are most useful when there is a specific reason to use them, such as helping manage symptoms or modify load.

Are custom orthotics better than store-bought orthotics?

Not automatically. The appropriate choice depends on your symptoms, activity, footwear and response to treatment.

Will orthotics make my feet weaker?

Orthotics don’t automatically weaken your feet. They can be used alongside strengthening exercises when appropriate.

Can I run with flat feet?

Yes. Many people with flat feet run without problems. If running causes pain, training load and lower-limb capacity should be assessed.

Should children with flat feet wear orthotics?

Not automatically. Flat feet are common in children. Treatment is more appropriate when symptoms or functional limitations are present.

Can physiotherapy help flat feet?

Physiotherapy can help improve foot, ankle, knee and hip strength and function and determine whether orthotics or other interventions may be useful.

Flat Feet Assessment and Treatment in Hamilton

If you have flat feet and you’re experiencing foot, ankle, knee, hip or lower-leg pain, you don’t necessarily need to “correct” your feet.

First, we need to determine whether they’re actually contributing to your symptoms.

At Restorative Touch Physiotherapy on Hamilton Mountain, we look at the entire lower limb—including your:

• Feet
• Ankles
• Calves
• Knees
• Hips
• Movement patterns
• Strength
• Activity levels

From there, we’ll build a treatment plan around your symptoms and your goals, rather than simply treating the appearance of your feet.

Depending on what we find, treatment may include:

• Foot and ankle exercises
• Progressive strengthening
• Mobility exercises
• Balance training
• Running or gait assessment
• Activity modification
• Footwear recommendations
• Orthotic assessment
• Custom orthotics when appropriate
• Return-to-sport rehabilitation

You don’t need to have a “perfect” arch to have strong, healthy feet.

You need feet that can handle the life you’re asking them to live.

If foot, knee, hip or lower-limb pain is limiting your walking, running, exercise or daily activities, book an assessment with Restorative Touch Physiotherapy on Hamilton Mountain.

Let’s figure out whether your feet are actually part of the problem—and what you can do about it. If you have flat feet, you may have been told that they are the reason your knees, hips or lower back hurt.

But is that actually true?

The answer is more complicated than “flat feet are bad.”

Some people have completely flat feet and never experience pain. Others develop foot, ankle, knee or hip symptoms that may be influenced by the way their feet move and how their body handles load.

What Is a Flexible Flat Foot?

A flexible flat foot means that the arch appears flattened when you’re standing but can reappear when the foot isn’t bearing weight or when you change how you’re loading it.

Flexible flat feet are common and aren’t necessarily problematic.

This can sometimes be associated with structural changes or conditions affecting the bones, joints or tendons of the foot.

Can You Fix Flat Feet?

This depends on what you mean by “fix.”

You generally can’t completely change the underlying bone structure of your foot through exercises.

But you may be able to improve:

• Foot strength
• Calf strength
• Balance
• Lower-limb control
• Tolerance to walking or running
• Symptoms

And those things may matter much more than whether your arch looks perfectly curved.

The goal of physiotherapy isn’t necessarily to create a textbook-looking arch.

It’s to help your foot become strong, comfortable and capable.

Exercises for Flat Feet

Exercises can help improve foot and lower-limb strength and control.

They aren’t designed to magically rebuild your arch overnight.

Here are some examples.

Exercise 1: Short Foot Exercise

Sit or stand with your foot flat on the ground.

Without curling your toes, gently draw the ball of your foot toward your heel to create a subtle shortening of the foot.

Hold for approximately 5–10 seconds.

Relax.

Repeat 8–12 times.

Important: Don’t aggressively claw your toes into the floor.

The goal is controlled foot activation.

Exercise 2: Calf Raises

Stand with your feet approximately hip-width apart.

Slowly rise onto your toes.

Pause at the top.

Lower yourself slowly.

Start with:

2–3 sets of 10–15 repetitions.

As you become stronger, progress to single-leg calf raises.

Your calf muscles play an important role in walking, running and absorbing and producing force.

Exercise 3: Single-Leg Balance

Stand on one leg.

Maintain your balance for 20–30 seconds.

Progress by:

• Closing your eyes
• Standing on a less stable surface
• Reaching with the opposite leg
• Performing a small squat

Start with:

3 × 20–30 seconds per side.

Exercise 4: Step-Down

Stand on a low step.

Slowly lower one heel toward the floor.

Keep your knee controlled over your foot.

Return to the starting position.

Try:

2–3 sets of 8–12 repetitions.

This exercise challenges the entire lower limb rather than just the foot.

Exercise 5: Single-Leg Calf Raise

Stand on one foot with something nearby for balance.

Rise onto your toes.

Pause.

Slowly lower.

Try:

2–3 sets of 8–15 repetitions.

Progress the exercise as your strength improves.

Do Foot Exercises Actually Raise Your Arch?

They may improve your ability to actively control the foot, but exercise isn’t guaranteed to permanently change the shape of your arch.

That’s okay.

A stronger foot doesn’t need to look dramatically different.

What matters is whether it can handle the demands you’re placing on it.

If your goal is to run, hike or play soccer without pain, improving your ability to tolerate those activities is more important than achieving a particular-looking arch.

• What surfaces are you running on?
• What does your running program look like?

Your feet can often adapt to running when the workload is increased appropriately.

Flat Feet and Running Injuries

If you’re a runner with flat feet and recurring injuries, it may be worthwhile to have your entire lower limb assessed.

Your physiotherapist may look at:

• Foot mechanics
• Ankle mobility
• Calf strength
• Knee control
• Hip strength
• Running mechanics
• Training volume

The goal isn’t to find something “wrong” with you.

It’s to identify factors that may be modifiable.

Flat Feet in Children

Flat feet are extremely common in children.

A child’s arch develops over time, and a low arch does not automatically mean they need treatment.

However, an assessment may be appropriate if a child has:

• Persistent foot pain
• Difficulty participating in activities
• Significant stiffness
• A noticeable change in foot shape
• Difficulty walking or running
• Symptoms that are affecting their quality of life

Parents shouldn’t feel that every flat foot needs to be “corrected.”

When Should You Be Concerned About Flat Feet?

You should consider an assessment if:

• Your feet are painful.
• Your arch has recently changed.
• One foot is significantly flatter than the other.
• You have difficulty walking.
• You have recurring ankle injuries.
• You have persistent plantar heel pain.
• Your knees hurt during walking or running.
• You’re developing unexplained lower-limb pain.
• Your symptoms are limiting sport or exercise.

A new, painful flat foot deserves particular attention.

Can Physiotherapy Help Flat Feet?

Yes.

Physiotherapy can help determine whether your foot mechanics are contributing to your symptoms and develop a treatment plan around your goals.

Treatment may include:

• Foot strengthening
• Calf strengthening
• Balance exercises
• Ankle mobility
• Hip and knee strengthening
• Gait retraining when appropriate
• Running assessment
• Activity modification
• Orthotic recommendations

The goal isn’t necessarily to “fix” the appearance of your feet.

It’s to improve how your entire lower limb functions.

A Better Way to Think About Flat Feet

Instead of asking:

“Are my flat feet causing my pain?”

Try asking:

“Are my feet strong enough and capable enough for what I’m asking them to do?”

That question is much more useful.

A flat foot that can comfortably handle 10,000 steps per day isn’t necessarily a problem.

A painful foot that struggles with 2,000 steps may need attention—even if it looks completely normal.

Your body’s capacity matters more than whether your anatomy looks perfect.

Frequently Asked Questions About Flat Feet

Are flat feet bad?

No. Flat feet are common and many people with flat feet have no symptoms.

Can flat feet cause knee pain?

They may contribute to knee symptoms in some people, but knee pain has many possible causes. An assessment can determine whether foot mechanics are relevant.

Can flat feet cause hip pain?

Potentially, but there isn’t a simple flat-feet-to-hip-pain relationship. Other factors such as hip strength, activity and previous injuries also matter.

Can flat feet cause plantar fasciitis?

Flat feet may be one contributing factor, but plantar heel pain is usually influenced by multiple factors, particularly how much load the foot is handling.

Can flat feet cause back pain?

There isn’t a simple rule that flat feet cause back pain. Lower-limb mechanics may contribute in some individuals, but back pain is influenced by many factors.

Can exercises fix flat feet?

Exercises can improve foot and lower-limb strength and control, but they aren’t guaranteed to permanently change the underlying structure of your arch.

Do I need orthotics for flat feet?

Not necessarily. Orthotics are most useful when there is a specific reason to use them, such as helping manage symptoms or modify load.

Are custom orthotics better than store-bought orthotics?

Not automatically. The appropriate choice depends on your symptoms, activity, footwear and response to treatment.

Will orthotics make my feet weaker?

Orthotics don’t automatically weaken your feet. They can be used alongside strengthening exercises when appropriate.

Can I run with flat feet?

Yes. Many people with flat feet run without problems. If running causes pain, training load and lower-limb capacity should be assessed.

Should children with flat feet wear orthotics?

Not automatically. Flat feet are common in children. Treatment is more appropriate when symptoms or functional limitations are present.

Can physiotherapy help flat feet?

Physiotherapy can help improve foot, ankle, knee and hip strength and function and determine whether orthotics or other interventions may be useful.

Flat Feet Assessment and Treatment in Hamilton

If you have flat feet and you’re experiencing foot, ankle, knee, hip or lower-leg pain, you don’t necessarily need to “correct” your feet.

First, we need to determine whether they’re actually contributing to your symptoms.

At Restorative Touch Physiotherapy on Hamilton Mountain, we look at the entire lower limb—including your:

• Feet
• Ankles
• Calves
• Knees
• Hips
• Movement patterns
• Strength
• Activity levels

From there, we’ll build a treatment plan around your symptoms and your goals, rather than simply treating the appearance of your feet.

Depending on what we find, treatment may include:

• Foot and ankle exercises
• Progressive strengthening
• Mobility exercises
• Balance training
• Running or gait assessment
• Activity modification
• Footwear recommendations
• Orthotic assessment
• Custom orthotics when appropriate
• Return-to-sport rehabilitation

You don’t need to have a “perfect” arch to have strong, healthy feet.

You need feet that can handle the life you’re asking them to live.

If foot, knee, hip or lower-limb pain is limiting your walking, running, exercise or daily activities, book an assessment with Restorative Touch Physiotherapy on Hamilton Mountain.

Let’s figure out whether your feet are actually part of the problem—and what you can do about it.
