Warm moist environments, such a bathrooms or locker rooms, are the most likely places for contracting the virus that causes plantar warts. To help reduce your risk, the American Podiatric Medical Association suggests the following: avoid walking barefoot, especially high-risk places; change shoes and socks daily; keep your feet clean and dry; avoid contact with warts on other people; and don’t ignore skin growth or changes.
