where do calluses on your feet come from
Callus A callus is an area of thickened skin in response to repeated friction, pressure, or other irritation. Rubbing that is too frequent or forceful will cause blisters rather than allow calluses to form. Since repeated contact is required, calluses are most often found on feet because of frequent walking and incorrectly fitting footwear. Calluses are generally not harmful, but may sometimes lead to other problems, such as anskin ulceration or infection or cause the sufferer to try and offload the effected painful area, which can place excessive stress on the asymptomatic side.
Tarsus (skeleton) The talus bone or ankle bone is connected superiorly to the two bones of the lower leg, the tibia and fibula, to form the ankle joint or talocrural joint; inferiorly, at the subtalar joint, to the calcaneus or heel bone. Together, the talus and calcaneus form the hindfoot.[1]
