What is a plantar callus?

A plantar callus is a thick, hardened area of skin that develops on the sole of the foot. Calluses are often caused by repeated friction or pressure, such as from walking or running barefoot, or from wearing shoes that don't fit properly. Plantar calluses can be unsightly and uncomfortable, and they can sometimes lead to pain or infection. In most cases, plantar calluses can be treated with simple home remedies, such as soaking the foot in warm water and Epsom salt, and applying a moisturizer. However, if a plantar callus is severe or painful, it may be necessary to see a doctor for treatment.
