What are Plantar Warts?

Plantar warts are small, rough growths that develop on the soles of the feet due to a viral infection caused by the human papillomavirus (HPV). These warts typically appear on weight-bearing areas such as the heels or balls of the feet, where pressure can cause them to grow inward beneath thick layers of skin. While generally harmless, plantar warts can be painful, especially when walking or standing.

What causes Plantar Warts?

Plantar warts are caused by direct contact with HPV, which thrives in warm, moist environments such as locker rooms, public showers, and swimming pools. The virus enters the skin through small cuts, cracks, or weakened areas on the feet. People with weakened immune systems or those who frequently walk barefoot in public areas are at a higher risk of developing plantar warts.

Symptoms of Plantar Warts

Common signs of plantar warts include:

  • A small, rough, grainy lesion on the sole of the foot

  • Thickened or callused skin over the wart due to pressure

  • Tiny black dots (clotted blood vessels) within the wart

  • Pain or tenderness when walking or applying pressure

Prevention & Treatment

To prevent plantar warts, it’s important to wear protective footwear in public areas, keep feet clean and dry, and avoid direct contact with warts on yourself or others.

Treatment options vary depending on the severity of the wart. Mild cases may resolve on their own, while persistent warts may require medical intervention. Common treatments include:

  • Over-the-counter salicylic acid to gradually remove the wart

  • Cryotherapy (freezing the wart with liquid nitrogen)

  • Prescription medications or stronger topical treatments

  • Surgical removal in severe cases

If you have persistent or painful plantar warts, consult a podiatrist for an appropriate treatment plan.
