Corns and Calluses

The pressure of calluses

Our feet play an important role in getting us around. When we walk or stand, our feet carry the burden of our body weight, as well as bearing the various pressures of movement and the constraints of footwear.

Sometimes, pressure placed on the foot becomes out of balance and extra friction falls on particular areas of the foot. When this happens, the body may respond to the pressure by producing thickening in the surface layer of the skin. These hard patches of skin are called calluses and are part of the body’s defense system to protect the underlying tissues. If the cause of pressure is not relieved, calluses become painful.

If pressure becomes concentrated in a small area, a hard corn may develop. Sometimes the pressure of the corn or callus may produce inflammation that can result in acute pain, swelling and redness.

Soft corns may form between the toes where the skin is moist sweat or inadequate drying. These appear white and rubbery and are also caused by excessive friction.  Corns and calluses are most often found on the balls of the feet or the tops of toes. They can also be found on heels and even along the sides of toenails.

What causes calluses and corns?

Calluses and corns are generally symptoms of underlying problems and in some cases, early warning of more complex foot disorders. Because they are caused by continuous pressure in one particular area, they may indicate abnormalities or deformity in bone structure or in the way a person walks.  Often calluses and corns are caused by ill-fitting or inappropriate footwear.

Who gets calluses and corns?

Almost everyone! In fact, calluses and corns affect more people than any other kind of foot problem. Some people have a natural tendency to develop calluses because of their skin type. For instance, elderly people have less fatty tissue and elasticity in their feet and because of a lack of padding; calluses may form on the bottom of the foot. Also, people who work in occupations that require them to spend a lot of time on their feet are prone to developing calluses.


Over-the -counter remedies such as corn paint and plasters generally only treat the symptoms – not the problem.  Also, they can easily damage the healthy skin surrounding the corn if not used properly. It is strongly recommended that commercial preparations only be used following professional advice.

It is important that you never cut corns or calluses yourself. In the warm, moist confines of enclosed shoes, infection can easily develop and small cuts can quickly become serious wounds.

Seeing your podiatrist

Jonathan and Wendy Hagon can not only recommend ways to relieve pain and get rid of the corn or callus, but can also help with isolating the cause and preventing the problem recurring.

To treat painful corns, your podiatrist will gently remove some of the hard skin of the callus so that the center of the corn can be removed.  To allow the callus to heal and prevent future cases, your podiatrist may redistribute pressure on the foot with soft padding and strapping or deflective appliances that fit easily into your shoes. For corns on the toes, small foam wedges are useful for relieving pressure in affected parts.

For older patients suffering from calluses on the soles of the feet, extra shock absorption for the ball of the foot can help to compensate for loss of natural padding.

Your podiatrist may also discuss the type of footwear most likely to cause corns and calluses. In some cases, special shoe inserts (orthoses) may be prescribed to reduce excessive weight bearing forces on the foot and provide long term relief.

Regular visits to your can help prevent foot problems, alleviate pain, and help keep you on your feet and mobile. So come in and see Jonathan or Wendy at Shore Footed Podiatry Ltd, at 157 Kitchener Road, Milford.  We are open 6 days a week and you can easily make an appointment on (09) 4891011.
