Plantar warts are noncancerous skin growths on the soles of your feet caused by the human papillomavirus (HPV), which enters your body through tiny cuts, breaks or other vulnerable sites on the skin of your feet.

Plantar warts often develop beneath pressure points in your feet, such as the heels or balls of your feet. This pressure also may cause a plantar wart to grow inward beneath a hard, thick layer of skin (callus).

Most plantar warts aren't a serious health concern and may not require treatment. However, plantar warts can be bothersome or painful. If self-care treatments for plantar warts don't work, you may need to see your doctor to have them removed.
