A callus is an area of thickened, hardened skin on the underside of the foot, usually found in the weight-bearing areas (i.e.: the balls of the feet and bottom of the heel). Callus formation is our skin’s way of protecting itself from pain and blisters, by providing extra cushioning in areas exposed to prolonged friction and pressure.  They are similar to corns and are formed by the same processes and causes.

Calluses are normal and usually harmless; almost everyone has them to some extent.  However, if they get too thick, they can cause pain and make walking difficult. An overgrown callus can also crack, fissure, and get infected.  

The most frequent cause of problematic calluses is shoes that don’t fit properly:  Ill-fitting shoes put excessive pressure and force on certain parts of the foot.  Calluses commonly form at the balls of our feet by the base of the toes, which is responsible for bearing most of our body’s weight.  

Calluses typically cover a larger area than a corn, and the thickened skin is evenly distributed through the callus (conversely, the thickened skin in a corn is concentrated in its center).   Calluses also usually form on the weight-bearing underside of the foot, whereas corns often form between or on the tops of toes.  

Most calluses do not require medical attention.  However, if you have diabetes or any other condition that causes poor circulation in your feet, you should promptly consult a chiropodist to avoid complications.  You can also see a foot specialist if your callus is causing you pain, irritation and discomfort, or affecting your ability to carry out daily activities.  

A licensed chiropodist will safely remove your calluses using chemical and/or mechanical therapies. See our Callus and Skin Care Services page for more information about how we can treat your calluses. 

If you have recurrent calluses, shoe inserts or custom orthotics may be indicated.  These will address any biomechanical abnormalities affecting your gait that may be contributing to your calluses.  

Never try to cut or shave away your callus with a sharp object.

Our Toronto foot clinic is open Monday-Friday from 9 am-6 pm, Saturdays from 9 am-4 pm and Sundays from 10 am to 4 pm. You do not need a referral to become a patient at our Foot clinic.

To prevent or reduce your susceptibility to developing calluses, you can:

• Wear shoes that fit correctly and comfortably:  Our foot clinic can help you find a proper-fitting shoe that accommodates bony deformities, provides extra support and cushioning, and suits your foot type and gait pattern.  
• Moisturize your feet regularly
• Exfoliate your feet
• Correct any biomechanical abnormalities with orthotics: An orthotic will correct faulty foot mechanics and redistribute your bodyweight appropriately.  This relieves the stress and pressure placed on callus-prone areas.  A chiropodist or foot specialist can assess and prescribe a custom orthotic that specifically accommodates your unique needs. 
• Get periodic medical pedicures:  Our licensed chiropodists provide medical pedicures to address any developing concerns or abnormalities with the feet.  In addition to properly and safely removing any thickened formed calluses, a medical pedicure also strengthens the skin on the feet, which reduces the risk of developing future issues.
