Warts are one of a number of soft tissue conditions of the foot that can be quite painful. They are caused by a virus, which invades the skin through small or invisible cuts and abrasions. They can appear anywhere on the skin, but only those on the bottom of the foot are called plantar warts.
Children, especially teenagers, tend to be more susceptible to warts than adults; some people are immune to warts.
