Corns are circular, cone-shaped areas of toughened skin on the feet usually due to repeated pressure and friction from ill-fitting footware. Corns commonly occur on the tops of the toes. Unlike a callus, a corn has a central, thickened area. A callus is a more diverse thickening of the skin. A corn can form under a callus or be surrounded by one.

Someone may be at an increased risk for corns if they have another foot problem such as hammertoes. A deforming condition such as hammertoes can cause the skin on the top of the effected toe to rub against shoes. If a corn forms, a doctor should be consulted to check for possible underlying causes, such as bone spurs.

To prevent corns, shoes should be selected for optimal foot health. Shoes should have a wide toe box. Narrow toe boxes as are common in shoes with pointed toes can cause undue pressure on the surfaces of the feet, especially the toes. Heels should be low or moderate in height. High heels place more pressure on the toes and the ball of the foot. Shoes should have adequate support and cushioning.

There are several treatment options for corns. Over-the-counter treatment options for corns include corn pads, foot baths, pumice stones, lotions, and callus removers. If a corn becomes painful, medical treatment is suggested. A doctor can recommend the best treatment for the corn. If the corn is removed but the underlying cause of the corn is not corrected, the condition may recur. Severe cases may require surgery.

Corns that are left untreated or are improperly cared for may get infected. If someone with a corn continues to wear ill-fitting shoes, the constant pressure will not allow the corn to heal. If a person tries to remove the corn by cutting it, the area becomes prone to infection. When dealing with corns, it is best to seek medical advice.
