Callus
A callus is a build-up of skin caused by external forces, such as sheering and pressure. The increased force on the skin causes an increase in the formation of keratin to protect the area, which is what we see as thick skin.
Common areas to find calluses are on heels, under the big toe, and under the balls of your feet.
Corn
A corn is similar to a callus, in that it is a build-up of keratin, but is caused by direct pressure. The direct pressure is the reason why corns tend to have a focused area of hard skin, whereas calluses are generally more diffuse.
Contrary to some belief, there is no "root" to a corn. The corn forms a concentrated core of keratin in the centre, which can be removed or "enucleated" by a Chiropodist. Removal paired with alterations in footwear and/or offloading will increase the success of treatment.
