Calluses develop when the skin produces extra layers in response to constant rubbing or pressure. This often happens on the soles of the feet due to walking or tight shoes, or on hands from manual labor. While they serve a protective purpose, excessive callus buildup can crack or cause discomfort during everyday activities.
Calluses typically appear as dry, thickened, rough, or waxy patches of skin. They may be grayish or yellowish in color and less sensitive than surrounding skin. Unlike corns, calluses usually aren’t painful unless they crack or put pressure on nerves. Some may notice tightness or burning sensations if calluses grow excessively.
Friction from shoes, walking barefoot, sports, or repeated hand use (e.g., writing, weightlifting) are common causes. Wearing ill-fitting footwear or having foot deformities like bunions or hammertoes can increase the risk. People with diabetes should be cautious, as untreated calluses may lead to complications like ulcers.
Soaking the affected area in warm water, gently exfoliating with a pumice stone, and applying moisturizing creams can soften and reduce calluses. Over-the-counter pads or insoles may relieve pressure. In more severe cases, a podiatrist may need to trim the callus or recommend custom orthotics for long-term relief.
Seek medical attention if a callus becomes painful, cracks, bleeds, or shows signs of infection. Individuals with diabetes or circulatory problems should never self-treat foot calluses. A healthcare provider can ensure there are no underlying conditions and help manage symptoms safely and effectively.
