Plantar Warts are a small growth on the skin that develop when the skin is infected by a virus. Warts can appear on the heels or other weightbearing areas of your feet, but typically they appear on the bottom (plantar side) of the foot. Plantar Warts most commonly occur in children, adolescents, and the elderly.
Plantar warts grow deep into the skin. Usually this growth occurs slowly, with the wart starting small and becoming larger over time.
