A callus is the condition in which skin becomes tough and hard. It occurs in response to repeated pressure, irritation and friction. It is basically a body’s defense mechanism to protect the foot against friction and pressure. These are usually formed on the base of the foot, inside of the big toe and the heel. Diabetics are more prone to develop calluses.


Calluses are formed due to an excessive amount of pressure on a particular area of the foot. Some other causes include the use of high-heeled shoes, narrow toe dress shoes, obesity, abnormal gait style, high arched feet, flat feet, loss of the fat pad in the sole of the foot and bony prominences.


The signs of the callus include a thickened hard skin patch on the foot or a hard bump at the base of the big toe. Pain occurs due to friction or pressure.

Treatment (non-surgical)

The main treatment is to correct the underlying cause. Calluses and corns normally heal themselves over time. If you want to remove them early you can use a keratolytic agent containing salicylic acid. Creams and lotions may be used to soften the callus and different pads and cushions maybe used to reduct and prevent them. Orthotics can also be used to transfer pressure and allow the callus to heal. It is especially important to take care of your feet and correct these problems if you are diabetic.
