What Can Cause Foot Blisters?

Blisters are a natural defense mechanism the body develops against damaged skin. They are defined as a small area that is filled with liquid over the raw skin, and will gradually drain when new skin has formed. One of the most common causes of blisters is excessive friction, and this can happen from shoes and socks that are worn. Additional reasons why blisters can develop can include an allergic reaction from poison oak, ivy, or sumac, or from medical conditions, such as eczema or autoimmune diseases. It is beneficial to cover foot blisters with a protective pad, and this may be helpful in preventing the blister from draining prematurely. Wearing shoes that fit correctly is often an answer to limit blisters developing on the feet. If you would like more information about the cause and management of foot blisters, it is suggested that you consult a podiatrist who can provide you with the information you are seeking.

Blisters may appear as a single bubble or in a cluster. They can cause a lot of pain and may be filled with pus, blood, or watery serum. If your feet are hurting, contact one of our podiatrists of Tri-Town Podiatry. Our doctors can provide the care you need to keep you pain-free and on your feet.

Foot Blisters

Foot blisters are often the result of friction. This happens due to the constant rubbing from shoes, which can lead to pain.

What Are Foot Blisters?

A foot blister is a small fluid-filled pocket that forms on the upper-most layer of the skin. Blisters are filled with clear fluid and can lead to blood drainage or pus if the area becomes infected.


(Blister symptoms may vary depending on what is causing them)

  • Bubble of skin filled with fluid
  • Redness
  • Moderate to severe pain
  • Itching

Prevention & Treatment

In order to prevent blisters, you should be sure to wear comfortable shoes with socks that cushion your feet and absorb sweat. Breaking a blister open may increase your chances of developing an infection. However, if your blister breaks, you should wash the area with soap and water immediately and then apply a bandage to the affected area. If your blisters cause severe pain it is important that you call your podiatrist right away.
