Pes Cavus (High-Arched Foot)

Pes cavus, also known as a high-arched foot, is a foot shape in which the arch is higher than normal. In some people it causes no significant problems, while in others it can lead to foot pain, pressure points, ankle instability, calluses, difficulty fitting shoes, and problems during walking or sports.

Pes cavus is not a single condition with one cause. The deformity can range from mild and flexible to severe and rigid, and it may be associated with muscle imbalance, neurological conditions, previous injury, or individual foot structure. Treatment depends on the cause, severity, flexibility, symptoms, and how much the deformity affects daily life.

What Is Pes Cavus?

Pes cavus describes a foot with an abnormally high longitudinal arch. Compared with a normal foot, less of the sole may contact the ground while standing.

Because weight is concentrated on smaller areas of the foot, increased pressure may develop beneath the heel, outer border of the foot, and forefoot.

The deformity may involve not only the arch but also the heel, forefoot, toes, and ankle. For this reason, the entire lower limb should be evaluated rather than looking at the arch alone.

What Does a High-Arched Foot Look Like?

Typical findings may include:

• An unusually high arch
• Reduced contact between the midfoot and the ground
• A heel that tilts inward
• Increased pressure under the heel or forefoot
• Clawing or bending of the toes
• Prominence along the outer side of the foot
• Difficulty fitting normal shoes
• Uneven shoe wear

Some patients have a high arch in both feet, while others may have a more pronounced deformity on one side.

What Are the Symptoms of Pes Cavus?

Pes cavus does not always cause pain, but symptomatic patients may experience a wide range of problems.

• Pain beneath the ball of the foot
• Heel pain
• Pain along the outer side of the foot
• Recurrent ankle sprains
• Feeling that the ankle is unstable
• Painful calluses
• Claw toes or hammer toes
• Difficulty walking on uneven ground
• Foot fatigue during prolonged standing
• Difficulty with running or sports

Why Does Pes Cavus Cause Foot Pain?

In a high-arched foot, body weight may not be distributed evenly across the sole. Increased pressure can become concentrated beneath the heel and metatarsal heads.

If the heel also tilts inward, more load may pass through the outer side of the foot. This can contribute to recurrent ankle sprains, stress on the lateral foot, and instability.

Toe deformities can further change pressure distribution and create painful calluses or shoe irritation.

What Causes Pes Cavus?

Pes cavus can develop for different reasons. Some patients have a naturally high arch without an underlying disease, while others develop the deformity because of muscle imbalance or a neurological condition.

Possible causes may include:

• Inherited foot structure
• Neuromuscular conditions
• Muscle imbalance
• Previous nerve injury
• Previous trauma
• Residual deformity from childhood
• Other neurological disorders affecting the lower limb

Identifying the underlying cause is especially important when the deformity is progressive or significantly different between the two feet.

Pes Cavus and Neurological Conditions

A high-arched foot can sometimes be associated with neurological or neuromuscular conditions that alter the balance between muscles controlling the foot.

One example is Charcot-Marie-Tooth disease, but several other conditions can also contribute to cavus deformity.

When pes cavus is progressive, severe, associated with weakness, or markedly asymmetric, further neurological assessment may be considered depending on the clinical findings.

What Is Cavovarus Foot?

Many patients with pes cavus also have an inward tilt of the heel. This combination is often described as a cavovarus foot.

The inward heel position can shift weight toward the outer side of the foot and may increase the risk of ankle instability and recurrent sprains.

Determining whether the heel deformity is flexible or rigid is an important part of treatment planning.

Why Do People With Pes Cavus Have Recurrent Ankle Sprains?

When the heel tilts inward and the foot loads more heavily along its outer border, the ankle may be more likely to roll outward.

Repeated sprains can further weaken the lateral ankle ligaments and create chronic instability.

In some patients, treating the ankle ligaments alone may not be sufficient if the underlying cavovarus alignment continues to place the ankle at risk.

Pes Cavus and Peroneal Tendon Problems

A cavovarus foot may increase stress on the peroneal tendons along the outer side of the ankle.

Patients may experience pain, weakness, swelling, or tendon injury in this region, particularly when recurrent ankle instability is also present.

Evaluation should therefore include the tendons and ankle ligaments as well as the shape of the foot.

Pes Cavus and Claw Toes

Muscle imbalance can cause the smaller toes to bend and develop clawing or hammer toe deformities.

These toe changes may create pressure on the tops or tips of the toes and can make footwear uncomfortable.

In advanced deformity, toe position may become rigid and may need to be addressed separately during treatment.

How Is Pes Cavus Diagnosed?

Diagnosis begins with a detailed orthopedic examination. The height of the arch, heel position, flexibility of the foot, toe deformities, ankle stability, muscle strength, and walking pattern are evaluated.

The examiner may also look for differences between the two feet and signs of muscle weakness or neurological involvement.

Because pes cavus is a three-dimensional deformity, examination while standing and walking is particularly important.

Why Are Weight-Bearing X-Rays Important?

Weight-bearing X-rays help evaluate the alignment of the foot while it is supporting body weight.

They can show the degree and location of the cavus deformity, heel alignment, forefoot position, arthritis, and other structural abnormalities.

Additional imaging such as MRI may be considered when tendon, ligament, cartilage, or other soft-tissue problems are suspected.

Is the High Arch Flexible or Rigid?

Flexibility is one of the most important factors when planning treatment.

A flexible deformity can partially correct when the foot is repositioned, while a rigid deformity remains fixed because of structural changes in the joints and bones.

Flexible and rigid cavus feet may require very different treatment strategies.

What Is the Coleman Block Test?

The Coleman block test is a clinical examination used in some patients with cavovarus deformity to help determine whether the inward heel position is flexible and driven primarily by the forefoot.

During the test, the outer part of the foot is positioned on a block while the first ray is allowed to drop freely.

Changes in heel alignment can provide useful information for surgical planning and help identify which part of the deformity is driving the abnormal position.

How Is Pes Cavus Treated?

Treatment depends on symptoms, cause, flexibility, degree of deformity, ankle stability, and the presence of associated tendon or toe problems.

Patients with mild and flexible deformities may often be treated non-surgically. Surgery may be considered when pain, instability, progressive deformity, or functional limitation persists despite appropriate conservative care.

Non-Surgical Treatment for Pes Cavus

Can Insoles Help High-Arched Feet?

Orthotic devices may help some patients by redistributing pressure away from overloaded areas and improving stability.

The design should be based on the patient's specific foot alignment rather than simply adding more support beneath the already high arch.

An orthotic that is appropriate for one type of cavus foot may not be suitable for another, so clinical assessment is important.

Can Pes Cavus Be Corrected Without Surgery?

Non-surgical treatment can reduce pain and improve function in many patients, particularly when the deformity is mild or flexible.

However, orthotics and exercises generally do not permanently reshape a rigid structural deformity.

The aim of conservative treatment is therefore often to improve pressure distribution, stability, comfort, and function rather than completely change the shape of the foot.

When Is Surgery Considered for Pes Cavus?

Surgery may be considered when a high-arched foot causes persistent pain, recurrent ankle instability, progressive deformity, difficulty walking, or significant pressure problems despite appropriate non-surgical treatment.

Surgical planning must identify which parts of the foot are driving the deformity and whether those components are flexible or rigid.

The goal is to create a more balanced, plantigrade, stable foot rather than simply lowering the arch.

Pes Cavus Surgery

There is no single operation for all patients with pes cavus. Surgery is usually tailored to the individual deformity.

Depending on the findings, treatment may involve a combination of tendon balancing, soft-tissue procedures, osteotomies, toe correction, ankle stabilization, or fusion procedures in advanced rigid deformities.

Several procedures may need to be combined because cavus deformity often affects multiple parts of the foot at the same time.

Osteotomy for Pes Cavus

Osteotomy means surgically cutting and realigning a bone. It may be used to correct abnormal alignment in selected flexible or partially flexible cavus deformities.

Depending on the source of the deformity, an osteotomy may be performed in the heel, forefoot, or other bones of the foot.

The exact correction is planned according to standing examination and weight-bearing imaging.

Heel Osteotomy for Cavovarus Foot

If the heel remains significantly tilted inward, a calcaneal osteotomy may be considered to reposition the heel and improve weight distribution.

The purpose is to move the heel toward a more balanced position and reduce excessive loading along the outer side of the foot.

Whether a heel osteotomy is necessary depends on the flexibility and source of the deformity.

Tendon Transfer and Muscle Balancing

Muscle imbalance can play an important role in pes cavus, particularly in patients with neuromuscular conditions.

Tendon transfer procedures may be used in selected patients to reduce deforming forces and improve balance between muscle groups.

Tendon surgery is often combined with bone correction when structural deformity is also present.

When Is Fusion Surgery Used?

Fusion procedures are generally reserved for more advanced, rigid deformities or feet with significant arthritis that cannot be adequately corrected with joint-preserving techniques.

Fusion stabilizes selected joints in a more functional position but sacrifices movement at those joints.

The benefits and limitations should therefore be considered carefully during treatment planning.

Recovery After Pes Cavus Surgery

Recovery depends on the number and type of procedures performed.

Because correction may involve bone healing, tendon procedures, and soft-tissue reconstruction, a period of protection and restricted weight bearing may be required.

Rehabilitation is gradually introduced to restore strength, mobility, balance, and walking function.

Complex cavus reconstruction generally requires a longer recovery than isolated treatment of a single tendon or toe.

When Can I Walk After Pes Cavus Surgery?

The timing of weight bearing depends on the procedures performed and the progress of bone and soft-tissue healing.

Patients may initially use a cast or boot and may need crutches or another walking aid.

Weight bearing is increased gradually according to follow-up examination and imaging when necessary.

Can I Return to Sports After Cavus Foot Treatment?

Return to sport depends on the severity of the original deformity, treatment performed, strength recovery, ankle stability, and the demands of the sport.

Low-impact activities may be possible earlier than running, jumping, or sports involving rapid direction changes.

Return to high-impact activity should be progressive and based on functional recovery.

Can Pes Cavus Get Worse?

Some high-arched feet remain relatively stable throughout life, while others may progress over time.

Progressive deformity is particularly important when pes cavus is associated with a neurological or neuromuscular condition.

Increasing weakness, worsening ankle instability, new toe deformities, or a progressively higher arch should therefore be assessed.

When Should You See an Orthopedic Specialist?

An orthopedic evaluation may be appropriate if you have:

• Persistent pain in a high-arched foot
• Repeated ankle sprains
• Chronic ankle instability
• Painful calluses beneath the foot
• Progressive clawing of the toes
• Pain along the outer side of the foot
• Difficulty finding comfortable shoes
• Weakness or progressive change in foot shape
• Difficulty walking or participating in sports

Sudden or progressive neurological symptoms should also be evaluated appropriately because a high-arched foot can sometimes be associated with an underlying neuromuscular condition.

Pes Cavus Treatment in Antalya

High-arched feet can produce very different symptoms from one patient to another. Some patients mainly experience painful pressure beneath the foot, while others present with recurrent ankle sprains, tendon problems, claw toes, or progressive deformity.

During an orthopedic evaluation, arch height, heel alignment, flexibility, muscle strength, ankle stability, toe position, walking pattern, and weight-bearing X-rays can be assessed together.

Depending on the findings, treatment may include footwear modification, orthotic support, rehabilitation, bracing, or individualized surgical reconstruction in patients with persistent symptoms or significant structural deformity.

Frequently Asked Questions About Pes Cavus

What is pes cavus?

Pes cavus is a foot shape characterized by an abnormally high arch. It may be flexible or rigid and can sometimes be associated with other deformities of the heel, toes, and ankle.

Is a high arch always a problem?

No. Some people with high arches have no significant symptoms. Treatment is generally considered when pain, pressure problems, instability, or functional limitations develop.

Why do high arches cause ankle sprains?

A cavovarus foot can place more weight along the outer side of the foot and position the ankle in a way that makes rolling injuries more likely.

Can pes cavus cause calluses?

Yes. Increased pressure beneath the heel and forefoot can cause painful calluses, particularly under areas that repeatedly carry excessive load.

Can orthotics help pes cavus?

Properly selected orthotics may improve pressure distribution and stability in some flexible high-arched feet. Their design should match the individual pattern of deformity.

Can exercises flatten a high arch?

Exercises may improve strength, balance, and flexibility but generally do not permanently reshape a rigid structural high arch.

Is pes cavus hereditary?

It can be. Some people inherit a high-arched foot shape, while other cases are related to neuromuscular conditions or acquired muscle imbalance.

Does pes cavus always require surgery?

No. Many patients can be managed with footwear, orthotics, rehabilitation, and ankle support. Surgery is generally reserved for persistent symptoms, instability, progressive deformity, or rigid structural problems.

What surgery is used for a high-arched foot?

There is no single operation. Treatment may include tendon balancing, osteotomies, toe correction, ankle stabilization, or fusion depending on the individual deformity.

When should a high-arched foot be evaluated?

Evaluation is appropriate when the foot is painful, progressively changing, associated with repeated ankle sprains, or accompanied by weakness, toe deformities, or difficulty walking.
