When we walk or stand, our body weight is carried first on the heel and then on the ball of the foot, where the skin is thicker, to withstand the pressure. When this pressure becomes intense, growths, in the form of corns and callus, may appear.
Corns always occur over a bony prominence, such as a joint.
There are five different types of corns. The two most common are hard and soft corns. These develop in a similar way to hard corns. They are whitish and rubbery in texture, and appear between toes, where the skin is moist from sweat, or from inadequate drying. A state registered chiropodist will be able to reduce the bulk of the corn, and apply astringents to cut down on sweat retention between the toes.
