The symptoms of corns and calluses are abnormally thick, hardened skin, usually appearing on the toe joints and soles of the feet, but they can actually show up anywhere.
Corns or calluses are indicative of a bigger problem – poorly functioning arches of the feet.
What causes corns and calluses?
Wearing unhealthy footwear over extended periods of time causes the feet and their function to maladapt.
Corns and calluses occur when movement of the foot inside the shoe creates localized points of inappropriate pressure, rubbing, and friction.
