Foot corns are areas of thickened skin about the size of corn kernels. It is caused by excess pressure on one point on the foot. They typically form on top or between toes and often result from wearing shoes that are too tight.

The ideal and quick relief is by putting a thing gauze pad, corn pad or bandage between the affected toes to keep them from rubbing against each other. Softening the corn with oil and then sanding it with a pumice stone can also be beneficial.
