Corns are usually a small circular area of thickened hard skin that may appear yellow or white in colour. They can occur on the heels, the ball of the foot or most often on the toes. There are a few types of corn seen commonly on the feet: hard corns, soft corns and seed corns.


Hard Corn

The most common type of corn is a hard corn. As the name suggests they are hard to the touch and may feel like a small stone in your shoe while walking. They appear as hard round masses of yellow skin and are generally uncomfortable or painful on direct pressure.

Seed Corn

Seed Corns are hard structures which look like yellow ‘seeds’ – they most commonly form in areas of callus, but are not usually related to direct pressure.

Soft Corns

Soft corns are also quite common, and usually occur between the toes. These corns appear white and rubbery and are usually very sore when the toes rub against each other.


Corns are usually due to abnormal pressure producing hard skin on a specific area, and over time the hard skin forms into a central hard area or a corn. The area of hard skin then digs down onto good skin beneath, causing pain and discomfort. Pressure can be from poorly fitting footwear or due to the foot structure. If there is an abnormality of structure or in the way the foot functions when you walk, this can create abnormal pressures causing a corn to form.


Clinical Reduction: A podiatrist can reduce the corn. The procedure is usually quick and painless, and the reduction of pain and pressure is usually immediate. Biomechanical assessment: The podiatrist will evaluate your foot structure, movement available in your foot, standing and walking positions. your podiatrist may recommend an insole or orthotic to help reduce the pressure to prevent to corn from reoccurring.
