What is Corn / Callus?

“corn” or a “callus” is a thickened area of skin (hyperkeratosis) on the foot caused by pressure or repeated rubbing on the skin.  Over time, the repetitive friction and irritation causes the skin to produce a protective skin which may vary in size and symptom.

Corn/ Callus or Hyperkeratosis condition on the foot.


In general, thickened skins on top of the toes are called “corns” and on bottom of the foot are called “calluses”. Soft corn can develops between toes (Heloma Mole) and is kept soft by the moisture in the area


  • Ill fitting shoes are the primary cause of corns and/or calluses.
  • People with toe deformities such as hammertoe, claw toe or mallet toe, often suffer from corns because the top of the bent toe rubs against the shoe, causing pain and irritation.
  • Usually, soft corn between the toes are developed due to bony prominences

Symptoms of corns and calluses

  • Thickened skin on top of the toe, between the toes or on the bottom of the foot
  • Pain and redness  over the site of friction or irritation

Conservative Treatment:

  • Proper fitting of footwear
  • Routine reduction of callus by a healthcare professional, especially in patient with diabetes, peripheral arterial disease (PAD) or  immunocompromised
  • Padding to decrease friction on the skin
  • We advise against the use of medicated corn removal pads of any kind in any patient, especially in patients with diabetes, peripheral arterial disease (PAD) or immunocompromised.  The use of “medicated corn removal pads” in those who are at risk can cause infections which can lead to amputation.

Surgical Treatment:

Surgical intervention is recommended only if patient has failed conservative treatment options.  The specific type of surgical intervention depends on clinical findings of your condition.

We encourage you to consult with a foot and ankle  specialist for a complete assessment of your condition.
