Corns and Calluses
Corns are small circles of thick skin that usually develop on tops and sides of toes or the sole of the foot. However, they can form anywhere. Corns are often caused by wearing shoes that fit poorly. Shoes that are too lose can allow your foot to slide and rub. Certain shoe designs that place excessive pressure on an area of the foot, for example, high heeled shoes can squeeze the toes.
Corns often occur on bony feet as there is a lack of natural cushioning. They can also develop as a symptom of another foot problem, such as bunions. Where the joint of big toe points outwards, as the big toe begins to point inwards towards the other toes on same foot. Hammer toe-where toe is bent and fused at the middle joint.
Calluses are hard, rough area’s of skin that are often yellowish in colour. They can develop on the:
feet, usually around the heel area or on the skin under the ball of the foot.
Calluses are larger than corns and do not have such well defined edges. As callused is thick, it is often less sensitive to touch than the surrounding skin. Calluses form when skin rubs against something, bone, shoe, or ground. They often form over the ball of the foot because it takes most weight when walking or running.
