Blisters on the feet are small pockets of fluid that form as a protective response to friction, heat, or pressure. They commonly occur from wearing ill-fitting shoes, which cause rubbing, or during intense physical activities like running or hiking. Moisture from sweat can worsen friction, increasing the likelihood of blister formation. Other causes include burns, frostbite, or allergic reactions to footwear materials. Infections, such as athlete’s foot, may also trigger blistering, as can certain medical conditions like diabetes or eczema. Repeated stress in specific areas, like the ball of the foot or heel, makes these spots more prone to blisters. Proper footwear, moisture-wicking socks, and reducing friction with protective padding can help prevent blisters. If blisters become frequent, painful, or show signs of infection, it is strongly suggested that you see a podiatrist for a proper diagnosis and effective treatment.

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 Comprehensive Foot & Ankle Center. 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.

Symptoms

(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.
