Calluses and corns are thick, protective layers of skin caused by friction and pressure.
Calluses tend to be larger, have less defined edges, and are rarely painful.
Corns are smaller, often have a hardened center, and can be painful.

Plantar warts and calluses may look similar and both tend to appear on load-bearing parts of the foot.
However, warts often have black or brownish dots and are caused by the human papillomavirus instead of pressure and friction.
