Ankle Pain When Squatting: Causes And The Best Exercises

Squatting looks like a simple movement, but it requires coordinated movement from the ankle, knee, hip, foot, and trunk.

As you lower into a squat, the shin moves forward over the foot and the ankle moves into dorsiflexion.

The deeper the squat, the greater the movement demands can become.

If your ankle hurts when squatting, the cause may be reduced ankle dorsiflexion, a previous ankle injury, joint irritation, tendon problems, altered foot mechanics, or simply a level of load or depth that your ankle does not currently tolerate well.

The location of the pain, the depth at which it appears, and whether you can squat without symptoms in a modified position can provide useful clues.

Why Does My Ankle Hurt When Squatting?

A squat requires the ankle to move while the foot remains in contact with the ground.

Research has found a relationship between ankle dorsiflexion and deep squat performance.

Other research shows that restricting ankle dorsiflexion can change movement at the knee, hip, pelvis, and trunk during squatting.

More recent research also found that people with limited ankle dorsiflexion may compensate with greater hip, pelvic, lumbar, and trunk movement during a bilateral squat.

This does not mean that limited ankle movement automatically causes pain.

Instead, it means that ankle mobility is one factor worth assessing when squatting is painful or feels restricted.

1. Limited Ankle Dorsiflexion

Dorsiflexion allows the shin to move forward over the foot while the heel remains grounded.

If your available dorsiflexion is limited, you may notice that your heels lift, your feet turn outward, your trunk leans forward, or your squat depth changes.

A 2024 study found that ankle dorsiflexion range was associated with deep-squat performance, while other studies have demonstrated changes in lower-limb mechanics when dorsiflexion is restricted.

However, limited dorsiflexion is not automatically a problem.

Some people naturally have different ankle ranges because of anatomy, previous injuries, training history, or individual movement strategies.

The important question is whether the available movement is sufficient for the squat you are trying to perform and whether it is associated with your symptoms.

2. Previous Ankle Sprain

An old ankle sprain can continue to affect movement long after the original pain has settled.

Some people develop persistent changes in ankle mobility, balance, strength, or movement coordination following a sprain.

These changes can become more noticeable during a squat because the ankle has to control a loaded movement through a relatively large range.

A 2021 clinical practice guideline for lateral ankle sprains and chronic ankle instability recommends assessing persistent impairments rather than assuming that symptom resolution means complete functional recovery (Martin et al., 2021).

3. Chronic Ankle Instability

If your ankle feels unreliable, wobbles, or seems as though it might give way during squatting, chronic ankle instability may need to be considered.

A 2024 study specifically examining squat biomechanics found that people with chronic ankle instability had less weight-bearing dorsiflexion and altered ankle, hip, and knee mechanics during squatting.

This is particularly relevant from a physiotherapy perspective.

The issue may not simply be “weak ankles.”

Balance, movement coordination, dorsiflexion, motor control, and the way the ankle shares load with the rest of the lower limb can all be relevant.

4. Anterior Ankle Impingement

Pain at the front of the ankle during a deep squat can sometimes be associated with anterior ankle impingement.

This condition is commonly suspected when anterior ankle pain is reproduced during dorsiflexion or squatting.

A recent review also notes that causes can include post-traumatic changes, instability, osteoarthritis, and repetitive microtrauma.

If the pain feels like a pinch or block at the front of the ankle as you approach deeper squat positions, this pattern is worth mentioning during assessment.

However, front-of-ankle pain does not automatically mean impingement.

5. Ankle Osteoarthritis

Ankle osteoarthritis can cause pain, stiffness, swelling, and reduced joint movement.

A deep squat may reproduce symptoms because the ankle is asked to move through a larger range while supporting body weight.

Previous trauma is a major contributor to ankle osteoarthritis, with approximately 80% of cases described as post-traumatic in a comprehensive review.

If you also have persistent stiffness, swelling, reduced ankle movement, or pain during other weight-bearing activities, joint-related causes may need to be assessed (Herrera-Pérez et al., 2022).

6. Achilles Tendon Problems

The calf-Achilles complex contributes to controlling ankle movement during squatting.

If the Achilles tendon is sensitive to loading, a deep squat may reproduce pain around the back of the ankle or above the heel.

However, squatting alone cannot diagnose Achilles tendinopathy.

Symptoms during walking, running, jumping, calf raises, and other loading tasks are also relevant.

The 2024 clinical practice guideline for midportion Achilles tendinopathy covers clinical examination, diagnosis, load management, and physical therapy interventions (Chimenti et al., 2024).

7. Peroneal Tendon Problems

The peroneal tendons run along the outside of the ankle and contribute to foot movement and lateral ankle stability.

Problems involving these tendons can cause outer ankle pain and may sometimes occur alongside ankle instability or previous ankle injury (Davda et al., 2017).

If squatting repeatedly causes pain along the outer ankle, particularly after previous sprains, a clinician may assess the peroneal tendons along with the lateral ankle structures.

8. Inner Ankle or Posterior Tibial Tendon Problems

Pain along the inside of the ankle can have several possible causes.

The posterior tibial tendon is one structure that may be relevant because it contributes to foot and arch control.

However, inner ankle pain should not automatically be labelled as posterior tibial tendon dysfunction.

Joint irritation, ligament problems, foot mechanics, and other structures can produce similar symptoms.

A clinical assessment should determine whether the tendon is actually contributing rather than relying on pain location alone.

9. Previous Fracture or Significant Joint Injury

A previous ankle fracture or significant joint injury can affect mobility and the way the ankle tolerates loading.

A deep squat may expose these limitations because it requires a greater combination of ankle movement and weight-bearing than ordinary standing.

If your ankle pain began after a previous fracture or significant injury, that history is important.

Persistent symptoms following major injury may also warrant medical review if they have not been appropriately investigated.

10. Squatting Deeper Than Your Current Capacity

Sometimes the problem is not squatting itself.

You may simply be asking the ankle to tolerate more depth, load, or repetitions than it currently can.

This can happen when someone:

• Starts deep squatting suddenly
• Increases weightlifting volume
• Returns to the gym after a break
• Changes squat technique
• Adds high-volume leg training
• Begins training at greater depth

A 2024 biomechanical review emphasizes that squat depth, stance width, foot rotation, trunk position, and tibial position can all change the mechanical demands of the squat.

Therefore, changing one variable may alter symptoms without necessarily “fixing” the underlying problem.

11. Foot Position Can Change the Ankle Demand

Your foot position can influence how the ankle behaves during a squat.

Changing stance width or foot rotation can change the movement demands placed on the ankle and other joints.

This does not mean there is one universally correct foot position.

A slightly different stance may feel more comfortable for one person because of their anatomy, mobility, training goals, or injury history.

The goal of physiotherapy is not to force everyone into the same squat technique.

It is to determine which movement strategy is appropriate and comfortable for the individual.

Where Does Your Ankle Hurt When Squatting?

The location of the pain can provide useful information, but it cannot establish the diagnosis by itself.

Pain at the Front of the Ankle

Front-of-ankle pain during a deep squat may occur when the ankle approaches its available dorsiflexion.

Possible contributors include restricted mobility, joint irritation, or anterior ankle impingement.

Pain at the Back of the Ankle

Pain behind the ankle may involve the Achilles tendon or other structures around the rear of the joint.

Symptoms during calf raises, running, jumping, or prolonged activity can provide additional clues.

Pain on the Outside of the Ankle

Outer ankle pain may involve the peroneal tendons or lateral ankle structures.

Previous sprains and feelings of instability are particularly relevant.

Pain on the Inside of the Ankle

Inner ankle pain can involve tendons, joints, ligaments, or structures within the foot.

Posterior tibial tendon problems are one possibility, but the location alone cannot identify the cause.

Why Does My Ankle Hurt Only When I Squat Deep?

A deep squat places the ankle through more dorsiflexion than many everyday activities.

You may therefore have enough movement for walking and standing but experience discomfort near the bottom of a squat.

This does not automatically mean deep squatting is damaging the joint.

It may simply mean that your current combination of range, load, speed, and control is not well tolerated.

Why Does My Ankle Hurt When Squatting but Not Walking?

Walking and squatting are different tasks.

Walking involves repeated smaller ankle movements, while a deep squat requires the ankle to move further while the foot remains planted.

This can reveal a mobility limitation or load-related sensitivity that is not obvious during walking.

The contrast is useful during physiotherapy because the clinician can compare how the ankle behaves during different functional tasks.

Why Does My Ankle Hurt When Squatting but Not Standing?

Standing requires relatively little ankle movement.

Squatting progressively increases ankle dorsiflexion and lower-limb loading.

If symptoms appear only as you descend, the range or loading introduced by the squat may be relevant.

A physiotherapist may observe whether changing squat depth, foot position, heel elevation, or movement speed changes the symptoms.

Why Does My Ankle Hurt When Squatting With My Heels Down?

Keeping your heels on the ground requires the ankle to move forward into dorsiflexion as you descend.

If dorsiflexion is restricted or painful, this position may expose the limitation.

However, lifting the heels does not automatically mean that something is wrong.

Squat mechanics vary between individuals, and heel elevation can intentionally change ankle and lower-limb demands.

The important question is whether your chosen technique is appropriate for your goals and tolerated by your ankle.

Why Does My Ankle Hurt When Squatting After an Old Sprain?

An old sprain can leave changes in ankle mobility, balance, strength, or movement coordination.

Research on chronic ankle instability has found altered squat mechanics, including reduced ankle dorsiflexion on the involved side.

If the painful ankle is the same side as your previous injury, this history is worth discussing with a physiotherapist.

It does not automatically mean that the old sprain is the direct cause of the current pain.

Can Tight Calves Cause Ankle Pain When Squatting?

A tight-feeling calf can be associated with restricted ankle movement, but it is not automatically the cause of ankle pain.

Dorsiflexion depends on more than calf flexibility.

Joint mobility, muscle-tendon properties, previous injury, pain, anatomy, and movement strategy can all influence the available range.

This is why repeatedly stretching the calf without understanding the actual limitation may not solve the problem.

Can Weightlifting Shoes Help Ankle Pain During Squats?

An elevated heel can change the ankle position required to reach a particular squat depth.

Some people use weightlifting shoes for this reason.

However, changing footwear modifies the movement demands.

It does not necessarily address why the ankle is painful.

If you consistently need a particular shoe to avoid ankle pain, it may be useful to assess the underlying mobility, loading, or movement issue.

Can Body Weight Cause Ankle Pain When Squatting?

Body weight affects the load placed through the lower limbs during a squat.

However, ankle pain should not automatically be attributed to body weight.

Joint health, previous injury, mobility, strength, training volume, squat depth, and load tolerance can all contribute.

A physiotherapy assessment should focus on the factors that can actually be modified rather than reducing the explanation to body weight alone.

Can Squatting Damage Your Ankles?

Squatting is not inherently harmful to healthy ankles.

The ankle is designed to move and tolerate load.

Problems can occur when an underlying condition is present or when the combination of range, load, volume, or training frequency exceeds the person’s current tolerance.

There is therefore an important difference between “squatting hurts my ankle” and “squatting is damaging my ankle.”

Pain is a reason to assess the movement, not automatic proof of tissue damage.

Should You Stop Squatting If Your Ankle Hurts?

Not necessarily.

If symptoms are mild and you can move safely, modifying the squat may be more useful than completely stopping lower-body exercise.

Depending on the cause, modification might involve temporarily reducing:

• Squat depth
• External load
• Repetitions
• Training frequency
• Speed
• Other exercises that significantly aggravate the ankle

The goal is to maintain appropriate activity without repeatedly provoking symptoms.

If pain is increasing or affecting normal weight-bearing, assessment is more appropriate than repeatedly testing the ankle.

Can Ankle Mobility Exercises Help?

They can help when restricted mobility is genuinely contributing to the movement problem.

But mobility exercises are not automatically appropriate for every ankle condition.

A person with a genuine mobility restriction may benefit from targeted mobility work, while someone with significant joint irritation, acute injury, or another underlying condition may need a different approach.

The aim is to improve useful movement without repeatedly aggravating symptoms.

Can Strengthening Help Ankle Pain During Squats?

Strengthening can be useful when reduced muscle capacity contributes to the problem.

Depending on the assessment, rehabilitation may target:

• Calf strength
• Foot and ankle strength
• Balance
• Proprioception
• Lower-limb control
• Progressive load tolerance

For chronic ankle instability, exercise-based rehabilitation is supported by clinical guidelines and recent research.

The programme should still be individualized to the person’s specific impairments.

What Does a Physiotherapist Check?

A physiotherapist may assess:

• Weight-bearing ankle dorsiflexion
• Other ankle movements
• Calf strength and endurance
• Foot position and control
• Balance and stability
• Squat depth
• Squat movement pattern
• Heel position
• Knee and hip movement
• Previous ankle injuries
• Swelling and symptom behaviour
• Training volume
• Recent changes in activity
• Response to different loads

The important part is that the ankle should not always be assessed in isolation.

A squat is a whole lower-limb movement, so the physiotherapist may examine how the ankle interacts with the knee, hip, pelvis, and trunk.

How Can Physiotherapy Help?

If the problem is appropriate for physiotherapy, treatment may include targeted mobility work, progressive strengthening, balance training, movement retraining, activity modification, and gradual return to deeper or heavier squatting.

The treatment depends on what the assessment finds.

For example, someone with restricted dorsiflexion may need mobility work combined with strengthening and functional retraining.

Someone with chronic ankle instability may need a greater focus on balance, strength, and movement coordination.

Someone with tendon-related pain may need carefully progressed loading rather than aggressive stretching.

This individualized approach is more appropriate than prescribing the same ankle exercises to everyone.

Can a Physiotherapist Diagnose the Cause?

A physiotherapist can assess musculoskeletal contributors to ankle pain and determine whether physiotherapy is appropriate.

However, not every cause of ankle pain is a routine physiotherapy problem.

If the history or examination suggests fracture, significant joint pathology, infection, or another condition requiring medical investigation, referral to an appropriate medical professional may be necessary.

Recognizing when physiotherapy is appropriate is part of good clinical practice.

When Is Physiotherapy Not the First Step?

Medical assessment may be more appropriate if:

• The pain followed significant trauma
• You cannot bear weight normally
• There is substantial or rapidly increasing swelling
• The ankle looks deformed
• The joint becomes hot and red
• You have fever or feel unwell
• Pain is severe or rapidly worsening
• Symptoms suggest a fracture or significant joint injury

Physiotherapy can then become part of rehabilitation when appropriate.

Lesser-Known Fact: Your Squat Can Reveal an Ankle Mobility Problem

You may have enough ankle movement for ordinary walking but not enough comfortable movement for your preferred squat depth.

That does not automatically mean you have a “bad ankle.”

It may simply mean that your squat requires a greater combination of ankle range, strength, balance, and load tolerance than your current capacity provides.

Interestingly, research in people with chronic ankle instability has found measurable differences in weight-bearing dorsiflexion and squat mechanics compared with people without chronic ankle instability.

This is why observing the actual movement that causes symptoms can be more informative than testing ankle range alone.

When Should You See a Doctor?

Seek medical assessment if:

• You cannot bear weight normally
• The ankle is visibly deformed
• There is severe or rapidly increasing swelling
• Pain followed significant trauma
• The ankle becomes hot, red, or markedly swollen
• You develop fever or feel unwell
• Pain continues to worsen
• Symptoms persist despite reasonable activity modification

These features may require investigation beyond routine physiotherapy management.

Conclusion

Ankle pain when squatting can have several possible causes, including limited dorsiflexion, a previous ankle sprain, chronic ankle instability, anterior ankle impingement, ankle osteoarthritis, Achilles or other tendon problems, altered foot mechanics, or reduced tolerance to deep loaded movement.

The fact that squatting hurts does not identify the exact cause.

Pay attention to whether the pain appears only at deeper squat depths, whether your heels remain on the floor, where the pain occurs, and whether similar symptoms appear during walking, stairs, running, or other exercise.

If the pain keeps returning or limits your ability to exercise, a physiotherapy assessment can help identify relevant mobility, strength, balance, movement-control, and load-tolerance factors.

When symptoms suggest significant injury or another medical condition, medical assessment should take priority.
