What it is: All warts are viruses and easily transmitted via moist contact. Plantar refers to the soles of the feet, where the wart is found. “They are easily contracted and a difficult problem to eradicate once infected,” says Dr. Youner. Prevention, namely wearing flip-flops instead of walking barefoot in your gym locker room or at a public pool, is crucial.
How to treat: Most of the time, you are going to wind up at the podiatrist’s office to solve this one. But if you’d rather try the DIY route first, purchase a bottle of salicylic acid 17% ($10.49, walgreens.com) at your local drugstore and apply it before bed to the affected area using a cotton ball. Leave it overnight, then gently scrub the wart with a pumice stone in the morning to reduce its size. Over time, you may rid your foot of it completely (but unlikely).
