Corns, Callus, and Cracked Heels

Corns and callus develop when the body tries to protect itself from pressure or friction by thickening the surface layers of skin. While both are forms of thickened, hardened skin, they are different conditions.

Corns & Callus


What are Corns?


Corns are small areas of dead or thickened skin with a hard centre. They can be extremely painful but are very easily treated.


Hard corns develop from repeated pressure and are usually found on the tops or edges of the toes or the soles of the feet. Soft corns form between the toes due to pressure and moisture.


What is Callus?


Callus is a dense, flat area of hardened skin caused by repeated strain, friction or pressure. It typically occurs on the big toes, sides, balls or heels of the feet.


Causes of Corns and Callus


Corns and callus develop from repeated friction and pressure. Common causes include:

  • Ill-fitting shoes and socks
  • Bony prominences
  • Wearing shoes without socks
  • Smoking


Treatment of Corns and Callus:


Although corns and callus are different, both are easily treated. Treatment is performed painlessly by your podiatrist in the clinic, with instant relief after just one session.

Your podiatrist will also identify the underlying cause and provide advice on how to minimise and prevent them from recurring.


Cracked Heels (Heel Fissures)


What are Cracked Heels?


Cracked heels occur when the skin on your heels becomes dry, hard, flaky or crusty. This skin loses flexibility and splits, creating painful fissures.


Cracked heels can be treated effectively in the clinic, and self-care for prevention will also be discussed at your appointment.


Causes of Cracked Heels


Cracked heels are often caused by:

  • Going barefoot, wearing thongs or open-backed footwear
  • Standing for long periods
  • Naturally dry skin
  • Fungal infections
  • Obesity
  • Diabetes
  • Certain medications


Signs & Symptoms:


  • Dry, thick, rough or painful skin around the heel
  • Deep cracks in the skin
  • Bleeding around the heel


Treatment of Cracked Heels


Treatment is similar to that for corns and callus. Using specialised equipment, your podiatrist will remove the dry, hard skin and smooth the area. For deeper cracks, dressings may be applied to promote healing.


Ongoing prevention and management may include regular podiatry visits, specific creams and footwear changes.
