Corns and Calluses


Corns and calluses are thick, hardened layers of skin that develop as the skin tries to protect itself against friction or pressure. They often form at higher pressure points on the bottom of the feet, or in between the toes if they are squeezed together in shoes.

Corns and calluses can cause pain and discomfort as when pressure is applied while standing and walking. Treatment entails trimming off the hard skin in a painless and non-invasive way, and addressing the source of friction and pressure.

About Corns and Calluses

Corns and calluses typically appear as:

  • A dry, thickened, rough area of yellowish skin
  • A hardened raised bump of skin
  • Tenderness or pain under the hard skin

Corns are smaller and deeper than calluses and have a hard centre. Due to this, they can be painful when pressed as they irritate the surrounding nerves in the skin. They typically form where there is more focal area of pressure or friction.

Calluses vary in size and shape and are often larger than corns. They are usually painless but can become painful when they are too thick. They generally form where there is a more diffused area of pressure or friction. Typically areas include the balls of the feet, and the heels.


Corns and calluses are caused by friction and pressure over a period of time. Some causes of it are:

  • Your foot biomechanics. The way your foot moves and how pressure is applied to the bottom of the foot while walking and running may lead to certain areas experiencing higher pressure than others. This leads to corns and calluses forming in these areas.
  • Wearing ill-fitting shoes. Tight and narrow shoes can squeeze areas of your feet causing high pressure spots. Also if your shoes are too big and loose, your foot may repeatedly slide and rub against the inside of the shoe.

When to seek medical help

If a corn or callus becomes painful and uncomfortable, seek help from your Podiatrist.

Individuals with poor sensation and blood flow in their feet such as diabetics should also seek regular routine care for their corns and calluses with a Podiatrist. This is because an untreated corn or callus can lead to a foot wound. These individuals should also seek advice before self-treating the corn or callus as even a minor injury can also lead to an infected open wound.

How We Help

To prevent and manage corns and calluses, we can help you with in the following ways:

  • Trimming away the hard skin. We can assist in paring down the thickened hard skin and trimming off the corn with a scalpel. This is non-invasive and pain-free. We would advise against using a sharp object to do so yourself at home as that can lead to a minor injury and cause an infection.
  • Thin the thickened hard skin safely on your own. Use a nail file, emery board or pumice stone to rub and thin the corn or callus safely on your own in the shower. This helps to remove a layer of thickened hard skin. If you’re unsure on how to do so, we can advise you on the best ways to do so.
  • Moisturise your corns and calluses. Use moisturiser on your corns and calluses to soften the hard skin build-up over time.
    Shoe selection and advice. Wearing shoes that are an appropriate size with good stability features can help even out pressure on the bottom of your feet and reduce corn and callus formation. By understanding your foot type and shape, we can advise on the appropriate shoes for you.
  • Foot orthotics. Foot orthotics can help even out the pressure on the bottom of your feet further by contouring your arch and heel areas. It can also improve your foot biomechanics so there are no high pressure areas on your feet when you walk and run.
