Have you had a blister on your foot? This fluid-filled pocket can be painful. Things can get messy if it becomes infected. There are many causes, but one of the top reasons is friction. The doctors at the New Jersey Podiatric Physicians & Surgeons Group are giving answers to the most commonly asked questions.

Where can blisters form on your feet?

The most common spots are the back of the heel, the sides of the foot, and the pinky toes. With each rub against a sock or shoe, the discomfort can increase. A blister forms beneath a thin layer of dead skin.

What is inside the fluid?

If you’re wondering what’s inside the fluid, here’s your answer: water and proteins. We encourage patients to keep the area clean and dry to avoid infection.

Why do people get blisters?

The culprit is friction or excessive rubbing. The top causes are improperly fitting shoes or repetitive activities, like sports. Another problem is sweaty feet, which can increase friction even more. As layers of your skin begin to separate from each other, fluid fills the gap in the form of a blister.

What can I do for prevention?

There are many benefits of wearing the right pair of shoes, and avoiding blisters is on the list. We encourage patients to choose comfortable shoes with support. Don’t forget to wear socks to reduce friction. For sports players, select shoes designed for physical activity.
