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.
In this guide we’ll explain:
What corns are
What calluses are
The key differences between them
What causes them
How they can be treated
When you should see a podiatrist
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.
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.
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.
A Word of Waring!
Please stay away from medicated corn pads!
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.
