Foot corns and calluses are small areas of thick, raised, hardened skin that cause pain.
They develop when there is excessive friction or pressure on the skin, usually from ill-fitting shoes or from lots of walking.
The medical term for a foot corn is a "Heloma Molle".
Corns and calluses are generally not a serious problem and can be easily treated with a combination of good foot hygiene, medication and orthotics. However occasionally they become infected or cause ulcers in which case surgery may be necessary.
Here we will look at the different types of foot corns and calluses, the common causes, best treatments options and how to prevent them from coming back again.
A callus is an area of thickened, hardened skin, which is usually painless. When the skin is exposed to excessive friction or pressure, it lays down extra layers to try and protect itself – a callus.
A callus can cover a large area but it is usually painless.
Foot calluses generally appear on the sole of the foot (underneath part) particularly around the toes as lots of your weight goes through these parts when you walk.
Foot corns tend to be smaller, more defined and are circular in shape than calluses. They are usually yellow/white in colour and have a transparent plug in the centre. Corns press into deeper layers of skin which causes damage and can make them very painful. In severe cases, foot corns can cause ulceration.
Corns on feet tend to develop either on the top, at the side or in-between toes. There are two main types of foot corns:
Hard corns are the most common type of foot corn. They are small, pale or yellow areas of raised, hardened skin, approximately pea-sized surrounded by a wider area of thickened skin.
Hard corns on feet, aka Heloma Durum, tend to occur over bony areas such as on top of the toes (usually the outer ones), on the side of the little toe or the ball of the foot. They usually develop due to friction from shoes
Soft corns, aka Heloma Molle, look different being white and rubbery. They are usually indented in the middle.
These foot corns are softened by moisture, usually from sweat or from not drying your feet properly. They tend to occur in-between the toes, usually the fourth and fifth toe when the toes rub against each other.
Calluses and corns on feet develop due to constant or repetitive pressure and friction on the skin. The most common causes of foot corns and calluses are:
There are lots of possible causes of foot lumps and your doctor can normally diagnose calluses and foot corns by asking about your lifestyle and looking at your feet and footwear.
They may want to do X-rays if they suspect there may be an underlying problem with the bone which is causing your corns on feet. Occasionally, they may perform a biopsy if there is a significant foot lump.
Treatment for foot corns and calluses aims to alleviate the symptoms and to cure the underlying cause to prevent them from coming back again. Typical foot corn treatment consists of:
You can gradually, gently rub away areas of hardened skin with the foot corn or callus using a pumice stone to get rid of any foot lumps. It helps to soak the foot for about 15-20 minutes first to soften the skin.
There should be adequate space in your shoes to prevent friction and callus formation. Ideally, shoes should have a rounded, wide toe box, have a soft top, be one centimeter longer than your longest toe and be flat (less than 4cm heel). If you have foot abnormalities, your podiatrist can advise you about specially designed shoes.
Foam wedges and toe spacers can help to prevent foot corns developing between your toes, and soft insoles reduce pressure on the bottom of the foot. A podiatrist will be able to advise you what products would best suit you.

You can get special creams designed to rehydrate areas of thick, dry skin which can be particularly useful with calluses. Lanolin is one of the most effective.
A podiatrist can use a scalpel to remove your foot corns or callus, known as trimming or pairing down. This should only ever be carried out by a trained professional. It is a painless procedure and people usually feel instant relief. The procedure may need to be repeated if the foot lump returns.
You doctor or podiatrist may apply a special form of salicylic acid which breaks down the hard skin, softening your foot corn. The skin becomes white and you can then trim or peel away the dead skin so the foot corn no longer sticks out.
Salicylic acid comes in different forms such as plasters, drops and pads and can be bought from a pharmacy but care should be taken when applying as they can burn healthy tissue. Only use them if directed by your doctor/podiatrist, and never use them if you suffer from diabetes or poor circulation as there is a risk of ulcer formation.

Occasionally the skin around corns on feet can become infected in which case it will be red and sore. This can be cleared up with a course of antibiotics, prescribed by your doctor.
If you get recurrent helomas due to a foot abnormality such as bunions, your doctor may recommend surgery to correct the bony deformity.
Foot corns and calluses often return if the cause of them is not properly addressed. There are a number of things you can do to prevent foot calluses and corns developing:
