Corns vs Calluses: What’s the Difference and Safe Removal Tips

If you’ve ever noticed thick, hardened areas of skin on your feet, you may have wondered whether

they are corns or calluses. These common foot conditions can look similar at first glance, but they

develop for different reasons and often require different treatment approaches.

Both corns and calluses form as the body’s natural response to repeated pressure or friction,

typically from footwear, walking patterns, or foot structure. While they may seem harmless, they

can sometimes become painful or lead to further foot complications if left untreated.

Understanding the difference between corns and calluses — and knowing when professional

treatment is necessary — is an important step toward maintaining healthy, comfortable feet.

In this guide, we’ll explain:

• What corns and calluses are

• The key differences between them

• What causes them to develop

• Safe ways to manage and prevent them

• When to see a podiatrist

What Are Corns?

Corns are small, concentrated areas of thickened skin that develop due to repeated pressure or

friction. They most commonly form on parts of the foot that experience direct pressure, such as the

tops or sides of toes or the balls of the feet.

Unlike calluses, corns tend to have a hard central core that presses into the deeper layers of the

skin. This can make them particularly painful when walking or wearing shoes.

Common locations of corns

Corns often develop in areas where shoes rub against the foot, including:

• The tops of toes

• The sides of toes

• Between toes (known as soft corns)

• Balls of feet

• Areas where toes press against footwearSymptoms of corns

People with corns may experience:

• A small, round patch of hardened skin

• Tenderness or pain when pressure is applied

• A hard central core

• Discomfort when walking or wearing certain shoes

Because corns are concentrated areas of pressure, even a small corn can become quite painful over

time.

What Are Calluses?

Calluses are larger, broader areas of thickened skin that develop when the skin tries to protect

itself from repeated friction or pressure.

Unlike corns, calluses typically do not have a central core and are usually less painful, although

they can still cause discomfort if they become very thick.

Common locations of calluses

Calluses tend to appear on weight-bearing areas of the foot, including:

• The balls of the feet

• The heels

• The sides of the feet

• Areas where the foot experiences repeated pressure during walking

They may also develop on the hands in response to repeated friction from manual work or sports

activities.

Symptoms of calluses

Calluses often present as:

• Thick, rough areas of skin

• Yellowish or hardened skin patches

• Skin that feels less sensitive than surrounding areas

• Mild discomfort or pressure when walkingWhile many calluses are painless, they can sometimes crack or become uncomfortable if they

become too thick.

Corns vs Calluses: The Key Differences

Although corns and calluses are both forms of thickened skin, there are several key differences

between them.

Size and shape

• Corns are typically small, round, and well-defined.

• Calluses are larger and spread across a wider area.

Pain level

• Corns are often painful due to the central core pressing into deeper skin layers.

• Calluses are usually less painful, although thick calluses can still cause discomfort.

Cause

Both conditions are caused by pressure or friction, but the distribution of pressure effects whether

a corn or callus forms.

Understanding these differences is important because treatment approaches may vary depending on

the condition.

What Causes Corns and Calluses?

Corns and calluses develop when the skin attempts to protect itself from repeated stress.

Common causes include:

Ill-fitting footwear

Shoes that are too tight, narrow, or loose can cause excessive friction on certain areas of the foot.

High heels and narrow toe boxes are particularly associated with corns on the toes.

Foot structure and biomechanics

Certain foot shapes or walking patterns can place extra pressure on specific areas of the foot.

Examples include:

• High arches• Flat feet

• Toe deformities such as hammer toes

• Abnormal gait patterns

Repetitive pressure from activities

Activities that involve repeated pressure on the feet can contribute to callus formation.

Examples include:

• Long periods of standing or walking

• Running and sports activities

• Occupations that require prolonged time on your feet

For people working in busy areas such as Sydney CBD hospitality, retail, or healthcare, foot

pressure can accumulate throughout the day.

Lack of protective cushioning

When the natural fat pads of the feet thin with age, the skin may experience increased pressure,

leading to callus formation.

Are Corns and Calluses Dangerous?

In most cases, corns and calluses are not dangerous. However, they can become problematic if they

cause ongoing pain or interfere with walking.

Complications may include:

• Increased discomfort when walking

• Skin cracking or splitting

• Infection if the skin breaks

• Difficulty wearing certain shoes

For individuals with diabetes or circulation problems, thickened skin on the feet can be

particularly concerning. These conditions increase the risk of wounds and infections, which is why

professional podiatry care is often recommended.

Safe Ways to Manage Corns and Calluses

Many people attempt to treat corns and calluses at home, but it is important to approach removal

safely.Improper treatment can sometimes lead to injury or infection.

Keep the skin moisturised

Dry skin is more likely to become thick and cracked.

Using a regular foot moisturiser can help keep the skin soft and prevent excessive buildup.

Reduce pressure on affected areas

Changing footwear or using cushioning pads may reduce pressure on the skin and prevent further

thickening.

Shoes with a wider toe box and good support can help reduce friction.

Avoid cutting or digging into the skin

It can be tempting to remove thickened skin yourself, but cutting into corns or calluses can damage

healthy skin and increase the risk of infection.

Be cautious with over-the-counter treatments

Some medicated corn removal products contain strong acids designed to dissolve thickened skin.

These treatments may not be suitable for everyone and can irritate surrounding skin if used

incorrectly.

For safe and effective removal, professional podiatry treatment is often the best option.

Professional Corn and Callus Removal

A podiatrist is trained to safely assess and treat corns and calluses.

During a podiatry appointment, treatment may include:

Careful reduction of thickened skin

Using sterile instruments, the podiatrist can gently remove excess skin without damaging the

surrounding area.

This procedure is typically quick and can provide immediate relief from pressure and discomfort.

Identifying the underlying cause

Simply removing the corn or callus does not address the reason it developed.

A podiatrist will assess factors such as:

• Foot structure• Walking patterns

• Footwear choices

This helps prevent the problem from returning.

Footwear advice

Your podiatrist may recommend specific types of shoes that reduce friction and pressure on the feet.

Orthotics if needed

In some cases, custom orthotics may be recommended to redistribute pressure across the foot and

prevent recurring skin thickening.

Preventing Corns and Calluses

While treatment can relieve symptoms, prevention is key to long-term foot health.

Choose supportive footwear

Shoes should provide enough space for your toes and offer proper support for your arch and heel.

Use protective cushioning

Padding or insoles can help reduce pressure on certain areas of the foot.

Maintain regular foot care

Keeping the skin moisturised and maintaining healthy nails can reduce friction and pressure.

Address foot pain early

If you notice persistent pressure points or skin thickening, seeking professional advice early can

prevent further complications.

When Should You See a Podiatrist?

It is a good idea to see a podiatrist if:

• Corns or calluses are painful

• Thickened skin keeps returning

• You have difficulty walking comfortably

• The skin becomes cracked or inflamed• You have diabetes or circulation issues

Early assessment can prevent minor problems from becoming more serious.
