👉 In the context of medicine, a calloused skin is characterized by the formation of calluses. Callouses are often found on the soles of feet and can be caused by repeated friction or pressure from shoes, especially those with rubber sole. These callouses may become infected, leading to redness, swelling, and pain. In some cases, callouses can also be a sign of an underlying skin condition such as ulcers or infections. It's important to consult a healthcare provider for proper diagnosis
