Causes and Symptoms of Foot Blisters

Blisters, those tiny pockets of annoyance that can develop on the feet, are often the result of friction, heat, and moisture conspiring against our skin. Blisters form as a protective response, shielding the delicate layers of skin beneath from further damage. Ill-fitting footwear, especially new shoes that have not been properly broken in, are common culprits. Extended periods of walking, running, or any repetitive motion can exacerbate the friction, triggering blisters. Additionally, sweaty feet trapped in damp environments provide the ideal environment. The symptoms are tender, swollen patches of skin filled with clear fluid, which may eventually rupture, leaving raw skin exposed. While prevention through comfortable footwear and moisture-wicking socks is key, understanding the causes and symptoms equips you to treat blisters promptly and prevent their unwelcome intrusion. If you frequently develop blisters on your feet, it is suggested that you contact a podiatrist who can provide you with additional prevention techniques.

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 Ernest Levi, DPM of Grand Central Podiatry. Our doctor 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.
