Calluses are hard, thick patches of skin that develop on the feet in response to pressure or friction. They are yellowish or pale in color and feel lumpy to the touch, but because the affected skin is thick, it may be less sensitive to touch than the skin around it. Calluses are often bigger and wider than corns, with less-defined edges. They commonly appear where the skin frequently rubs against something, such as a bone, footwear, or the ground. Calluses usually do not cause much discomfort, but they may become painful when a person puts pressure on them while walking in shoes.

There are over-the-counter products available to manage calluses, but they contain harsh chemicals that can injure the surrounding healthy skin if not applied precisely. It is important to follow the instructions exactly when using these products. A healthcare provider can diagnose calluses by looking at the skin, and no tests are required.

Home remedies for calluses include soaking and filing the feet and using a moisturizer. Pumice stones and creams are also recommended. However, if a callus or corn makes it hard to walk or do other activities, it may be wise to see a foot specialist (podiatrist). The doctor may find a structural problem with the feet or suggest special padding or shoe inserts to redistribute the forces that cause friction and pressure inside shoes.
