Corns vs Calluses: What’s the Difference?

Corns and calluses are both types of thickened skin that develop when the feet are exposed to repeated pressure or friction.

Although they may look similar, corns and calluses are actually different conditions and often require slightly different treatment approaches.

Understanding the difference can help you manage them more effectively and prevent them from returning.

What Are Corns?

Corns are small, concentrated areas of thickened skin that usually develop on parts of the foot where pressure is focused.

They commonly appear on:

• the tops of toes

• between toes

• the sides of toes

• areas where shoes rub against the skin

Corns have a hard centre which presses into the surrounding skin and can cause discomfort or pain.

Because corns are usually quite small but deeper than calluses, they can sometimes feel tender when pressure is applied.

What Are Calluses?

Calluses are larger areas of thickened skin that develop in response to repeated friction or pressure.

They most often appear on weight-bearing areas of the foot, including:

• the heels

• the balls of the feet

• the sides of the feet

Unlike corns, calluses tend to be broader and more spread out.

They are usually not painful, although very thick callus can sometimes become dry or cracked over time.

If the skin on the heels becomes excessively thick, it may lead to cracked heels or heel fissures, which can cause discomfort when walking.

Corns vs Calluses: Key Differences

Although they are both caused by pressure, there are several differences between corns and calluses.

Corns	Calluses
Small, focused area of thick skin	Larger, spread-out area
Often have a hard centre	Usually evenly thickened
Caused by direct pressure or rubbing	Caused by repeated friction

Understanding these differences can help determine the most appropriate treatment.

Are Corns and Calluses Dangerous?

Most corns and calluses are not dangerous and can often be managed with simple foot care measures.

However, they can sometimes become painful, particularly if the pressure causing them continues. Thick calluses may crack and become uncomfortable, while corns can become increasingly tender due to the pressure they place on the underlying tissues.

You should be particularly cautious if you have:

• Diabetes

• Poor circulation

• Reduced sensation in your feet

• Peripheral neuropathy

In these cases, even relatively minor areas of thickened skin can potentially lead to complications. If you have any of these conditions, it is often best to seek professional advice before attempting treatment yourself.

What Causes Corns and Calluses?

Corns and calluses both develop as a protective response when the skin experiences repeated pressure or friction.

Common causes include:

Tight or Poorly Fitting Shoes

Shoes that squeeze the toes or rub against certain areas of the foot can cause pressure points. Sometimes high heels which shift body weight onto the front of the foot, increasing pressure on the toes and ball of the foot can contribute as well.

Walking or Standing for Long Periods

People who spend long hours on their feet may be more prone to thickened skin.

Foot Structure or Biomechanics

Certain foot shapes or walking patterns can increase pressure in specific areas.

Walking Barefoot

Without the cushioning of footwear, the skin may thicken to protect itself.

Why Do My Corns and Calluses Keep Coming Back?

One of the most frustrating aspects of corns and calluses is that they often return after treatment.

This is because corns and calluses are not usually the primary problem themselves. Instead, they develop as the skin's natural response to repeated pressure or friction.

Common reasons they return include:

• Wearing tight or poorly fitting footwear

• Changes in foot shape

• Walking or standing for long periods

• Certain foot structures, such as bunions or hammer toes

• The way pressure is distributed through your feet when walking

Even when a corn or callus is removed, it may return if the underlying cause of the pressure remains.

For this reason, successful treatment often focuses not only on removing the thickened skin but also on identifying and addressing why it developed in the first place.

Should You Cut Corns or Calluses Yourself?

No. It is generally not recommended to cut, shave or attempt to remove corns and calluses using blades, scissors or other sharp instruments at home.

Trying to remove thickened skin yourself can:

• Damage healthy skin

• Cause pain or bleeding

• Increase the risk of infection

• Make the problem worse

This is particularly important if you have diabetes, poor circulation or reduced sensation in your feet.

If you wish to manage thickened skin at home, it is usually safer to:

• Use a gentle foot file

• Moisturise regularly

• Wear well-fitting footwear

• Seek professional advice if symptoms persist

When it comes to treating corns and calluses, gradual and gentle management is usually the safest approach.

How to Treat Corns and Calluses at Home

In many cases, mild corns and calluses can be managed with simple foot care.

However, it’s important to treat them safely and avoid methods that could damage the skin.

Reduce the Source of Pressure

Identifying and addressing the cause of pressure is the most important step.

This may include:

• wearing shoes with a wider toe box

• choosing well-cushioned footwear

• avoiding tight or narrow shoes

Reducing friction helps prevent the thickened skin from returning.

Moisturise the Skin

Keeping the skin hydrated helps soften thickened areas.

Foot creams containing ingredients such as urea are often used to help break down thick skin and improve hydration.

Regular moisturising can also help prevent dry skin and cracked heels.

Gently File Thick Skin

Using a foot file or pumice stone can help reduce callus build-up.

This should be done gently, ideally after bathing when the skin is softer.

Avoid:

• cutting the skin yourself

• using sharp tools

• aggressively filing the area

• 
  

Over-filing can damage the skin and lead to irritation.

Protective Padding

In some cases, protective padding or cushioning can help reduce pressure on the affected area.

Toe separators or protective pads may be helpful if corns develop between toes.

Do Corn Plasters Work?

Medicated corn plasters are widely available, but they are not usually recommended by podiatrists.

Many corn plasters contain salicylic acid, which works by breaking down thickened skin. However, the acid does not only affect the corn itself — it can also damage the healthy skin surrounding it.

This can lead to:

• Pain and irritation

• Skin breakdown

• Increased risk of infection

• Difficulty assessing and treating the corn properly

For people with diabetes, poor circulation or reduced sensation, medicated corn plasters can be particularly risky.

While they may temporarily soften the corn, they do not address the underlying cause of the pressure and often do not provide a long-term solution.

Can Corns and Calluses Be Prevented?

Although it is not always possible to prevent corns and calluses completely, there are several things you can do to reduce your risk.

These include:

• Wearing well-fitting shoes with adequate toe room

• Avoiding shoes that rub or create pressure points

• Moisturising regularly to maintain healthy skin

• Wearing appropriate socks

• Managing any underlying foot conditions

• Seeking advice early if you notice pressure areas developing

Regular foot care and addressing problems early can often help prevent thickened skin from becoming painful or difficult to manage.

When Should You See a Podiatrist?

While mild cases may improve with home care, professional treatment is sometimes necessary.

You should consider seeing a podiatrist if:

• the corn or callus becomes painful

• the skin becomes very thick

• home treatments are not improving the problem

• the area becomes inflamed or infected

• you have diabetes or circulation problems

• 
  

A podiatrist can safely remove thick skin and identify the underlying cause of pressure.

Addressing the root cause helps prevent corns and calluses from returning.

Preventing Corns and Calluses

Good foot care habits can reduce the likelihood of developing thickened skin.

Helpful steps include:

• wearing well-fitting shoes

• avoiding excessive pressure on certain areas of the foot

• moisturising regularly

• gently managing thick skin when it develops

Maintaining a consistent foot care routine at home can help keep the skin healthy and prevent many common foot problems.

Final Thoughts

Corns and calluses are very common foot conditions caused by repeated pressure or friction.

Although they may look similar, they have different characteristics and can develop in different areas of the foot.

Understanding the difference between corns and calluses can help you manage them more effectively and prevent them from returning.

If thickened skin becomes painful or persistent, professional advice from a podiatrist may help address the underlying cause.
