What are Corns and Calluses

Corns and calluses are common foot conditions that can cause discomfort and pain. They are characterized by thickened, hardened, or raised areas of skin that develop due to repeated friction or pressure on the feet. While they may seem like minor annoyances, corns and calluses should not be ignored as they can lead to complications if left untreated.


Corns are small, localized areas of thickened skin that usually develop on the tops or sides of the toes. They are typically round or cone-shaped and can be painful when pressed. Corns are often caused by ill-fitting footwear or abnormal foot mechanics, which cause excessive friction and pressure on specific areas of the feet.


Calluses, on the other hand, are larger and generally develop on the soles of the feet. They are flat and less painful compared to corns, but can still cause discomfort. Calluses are typically a result of excessive friction and pressure from activities such as walking or running. They can also develop due to bony deformities or dry skin.

Causes of Corns and Calluses

Understanding the causes of corns and calluses can help you prevent their development or recurrence. Here are some common factors that contribute to these foot conditions:

Ill-fitting footwear

Wearing shoes that are too tight or too loose can lead to the formation of corns and calluses. Tight shoes can squeeze the toes together, causing friction and pressure, while loose shoes can cause the feet to slide and rub against the shoe, leading to the development of these skin abnormalities.

Friction and pressure

Activities that involve repetitive friction and pressure on the feet, such as walking or running, can cause corns and calluses to form. Pressure points can develop when the weight of the body is not evenly distributed, leading to the thickening of the skin to protect the underlying tissues.

Abnormal foot mechanics

If you have abnormal foot mechanics, such as flat feet or high arches, you may be more prone to developing corns and calluses. These conditions alter the way weight is distributed on the feet, leading to areas of increased pressure and friction.

Bony deformities

Certain bony deformities, such as bunions or hammertoes, can contribute to the development of corns and calluses. These deformities often result in misalignments or protrusions of the bones, causing friction and pressure on specific areas of the feet.

Dry skin

Dry skin lacks the natural moisture and elasticity that help protect the feet from friction and pressure. As a result, dry skin is more prone to developing corns and calluses. Moisturizing your feet regularly can help prevent the occurrence of these skin conditions.

Symptoms of Corns and Calluses

Identifying the symptoms of corns and calluses is crucial in managing and treating these conditions. Here are some common signs to watch out for:

Thickened, hardened, or raised areas of skin

The primary characteristic of corns and calluses is the thickening and hardening of the skin. You may notice a localized area of skin that feels rough and raised compared to the surrounding healthy skin. Corns usually have a conical shape, while calluses are more flattened.

Tenderness or pain

Corns and calluses can be tender or painful to touch, especially when pressure is applied to them. The discomfort can range from mild to moderate, depending on the severity of the condition. Walking or wearing tight shoes may exacerbate the pain.

Flaky or dry skin

In some cases, corns and calluses can cause the skin to become flaky or dry. This is particularly common if the affected area is constantly subjected to friction and pressure.

Waxy, translucent appearance

Severe or longstanding corns and calluses may develop a waxy, translucent appearance. This is due to the buildup of dead skin cells and the hardening of the skin. The affected area may appear white or yellowish in color.

Prevention of Corns and Calluses

Preventing corns and calluses is key to minimizing discomfort and reducing the risk of complications. Here are some measures you can take to prevent their development:

Wear properly fitted shoes

One of the most effective ways to prevent corns and calluses is to wear shoes that fit properly. Avoid shoes that are too tight or too loose, as they can cause excessive friction and pressure on the feet. Opt for shoes that have adequate room in the toe box and provide good support.

Choose shoes made of soft materials

Choosing shoes made of soft materials, such as leather or suede, can help reduce the friction and pressure on your feet. Soft materials allow for better flexibility and breathability, decreasing the likelihood of corns and calluses.

Use protective pads or cushions

If you are prone to developing corns or calluses, consider using protective pads or cushions on the affected areas. These can provide a barrier between your feet and your shoes, reducing friction and pressure. Make sure to choose pads or cushions that are specifically designed for corns and calluses.

Moisturize your feet regularly

Keeping your feet moisturized is essential in preventing dry skin, which can increase the risk of corns and calluses. Apply a quality foot moisturizer daily, focusing on the heels and other areas prone to thickening. Avoid applying moisturizer between the toes, as excessive moisture can lead to fungal infections.

Keep your feet clean and dry

Maintaining good foot hygiene is crucial in preventing the development of corns and calluses. Wash your feet regularly with mild soap and warm water, and make sure to dry them thoroughly, especially between the toes. Moisture between the toes can create an environment that promotes fungal growth.

Home Remedies for Corns and Calluses

In addition to prevention measures, there are several home remedies that can help manage corns and calluses. These remedies are not intended to replace professional medical advice, but they can provide temporary relief and promote healing. Here are some home remedies you can try:

Soaking your feet

Soaking your feet in warm water can help soften the corns and calluses, making them easier to remove. Add some Epsom salt or mild soap to the water for added benefits. Soak your feet for about 15-20 minutes, and then gently rub the affected areas with a pumice stone to remove the dead skin.

Using a pumice stone

A pumice stone is a natural exfoliating tool that can help smooth out rough skin caused by corns and calluses. After soaking your feet, gently rub the pumice stone on the affected areas in a circular motion. Be careful not to scrub too hard, as it can cause further irritation or injury to the skin.

Applying moisturizer

After removing dead skin with a pumice stone, apply a moisturizer to keep the skin hydrated and prevent dryness. Look for a foot cream or lotion that contains ingredients like urea or salicylic acid, as they can help soften the skin and promote healing.

Wearing comfortable shoes

While prevention is key, wearing comfortable shoes can also provide relief from existing corns and calluses. Opt for shoes that have a wide toe box, good arch support, and cushioning. Avoid narrow or pointed-toe shoes that can worsen the condition.

Using corn pads or cushions

Corn pads or cushions are over-the-counter products that can provide temporary relief from the pain and pressure of corns and calluses. These pads are typically made of soft, flexible materials and have a hole in the center corresponding to the affected area. They can help cushion the affected area, reducing friction and pressure.

Treatment Options for Corns and Calluses

If home remedies and prevention measures are not effective in managing your corns and calluses, it may be necessary to seek professional treatment. A podiatrist or foot specialist can offer various treatment options depending on the severity of your condition. Here are some treatment options that may be recommended:

Trimming or debriding the thickened skin

A podiatrist can trim or debride the thickened skin of corns and calluses using sterile instruments. This procedure aims to safely remove the excess skin and relieve the pressure on the affected area. It is essential to have this procedure done by a trained professional to avoid injury or infection.

Using salicylic acid patches

Salicylic acid patches or plasters can be applied to the corn or callus to soften the skin and promote gradual removal. These patches typically contain a small amount of salicylic acid, which helps break down the thickened skin. Follow the instructions provided and consult a healthcare professional before using these products.

Using custom-made orthotics

If your corns or calluses are caused by abnormal foot mechanics, such as flat feet or high arches, custom-made orthotics may be recommended. Orthotics are shoe inserts designed to correct structural abnormalities and redistribute weight on the feet, reducing friction and pressure. A podiatrist can provide personalized orthotics based on your foot condition.

Surgical removal

In severe cases or when conservative treatments fail, surgical removal of corns or calluses may be necessary. This procedure involves the permanent removal of the thickened skin and underlying tissues. Surgical removal is typically reserved for persistent or painful corns and calluses that do not respond to other treatments.


Cryotherapy, or freezing, can be used to treat resistant corns and calluses. Liquid nitrogen is applied to the affected area, freezing and destroying the thickened skin. This procedure should be performed by a trained professional to minimize the risk of injury or damage to healthy tissues.

When to Seek Professional Help

While corns and calluses can often be managed with home remedies or over-the-counter treatments, there are situations where professional help should be sought. If you experience any of the following, it is important to consult a healthcare professional:

If the corn or callus becomes infected

Corns and calluses can become infected, leading to pain, redness, swelling, and discharge. If you notice signs of infection, such as increasing pain or the presence of pus, seek medical attention immediately. Infections require proper medical treatment to prevent further complications.

If there is severe pain or bleeding

Occasionally, corns or calluses can become particularly painful or start to bleed. This may be a sign of underlying tissue damage or a more serious condition. If you experience severe pain or bleeding, consult a healthcare professional for an evaluation and appropriate treatment.

If home remedies are not effective

If your corns or calluses persist despite diligent home care and preventive measures, it may be time to seek professional help. A foot specialist can assess your condition, provide a diagnosis, and recommend appropriate treatments. They can also address any underlying factors contributing to the development of corns and calluses.

Complications of Untreated Corns and Calluses

Ignoring corns and calluses can lead to complications that can significantly impact your foot health. Some of the potential complications include:


Untreated corns and calluses can become infected, especially if they are exposed to bacteria or fungi. Infections can cause pain, redness, swelling, and the formation of pus. In severe cases, infections can spread to the surrounding tissues or even the bloodstream, requiring immediate medical intervention.


Prolonged pressure and friction on corns or calluses can lead to the development of ulcers. Ulcers are open sores that expose the underlying tissues, making them vulnerable to infection. Diabetic individuals are particularly at risk for ulcers, as their impaired circulation and sensation can delay the detection and treatment of these wounds.


Cellulitis is a bacterial skin infection that can occur when corns or calluses become infected. The infection spreads into the deeper layers of the skin, causing redness, swelling, pain, and warmth. Untreated cellulitis can lead to serious complications and requires prompt medical attention.

Foot deformities

Continual pressure from untreated corns and calluses can result in foot deformities over time. The skin and tissues may become permanently altered, leading to misalignment or malformation of the bones and joints. These deformities can further contribute to the development of corns and calluses, perpetuating a cycle of discomfort and skin abnormalities.

Precautions for Diabetic Patients

Diabetic individuals need to take special precautions when it comes to managing corns and calluses. Diabetes can impair circulation and sensation in the feet, increasing the risk of complications. Here are some precautions to consider:

Avoid self-treatment

Due to the potential risks associated with corns and calluses, it is advisable for diabetic patients to avoid self-treatment. Attempting to remove corns or calluses at home can result in cuts, abrasions, or infections, which can be especially dangerous for individuals with diabetes. It is best to seek professional care from a podiatrist or foot specialist.

Get regular foot check-ups

Diabetic patients should schedule regular foot check-ups with a healthcare professional. These check-ups can help identify any potential issues early on and allow for prompt intervention. A healthcare professional can assess the condition of your feet, provide preventive care, and address any concerns or questions you may have.

Proper foot care

Maintaining proper foot care is essential for diabetic individuals to prevent complications. This includes practicing good foot hygiene, wearing properly fitted shoes, and inspecting your feet daily for any signs of corns, calluses, wounds, or infections. If you notice any abnormalities or changes, contact your healthcare provider immediately.


Corns and calluses are common foot conditions that can cause discomfort and pain. While they can be managed with proper prevention, home remedies, and professional treatment, it is important to seek help if the condition worsens or if there are complications, especially for diabetic patients. By following the recommended precautions and taking good care of your feet, you can reduce the discomfort and risks associated with corns and calluses.
