Why Do I Get Blisters on My Feet?

Tuesday, 29 March 2022 00:00

Blisters are usually caused by friction of something rubbing against the skin. A red, painful, swollen sore can develop on the foot from constant rubbing of a shoe, sock or other rough surface against the skin. This often turns into a blister. Interestingly, a blister is the body’s way of forming a protective shield filled with liquid to protect more delicate underlying tissue. Blisters can also be caused by less obvious irritants, burns, frostbite, or underlying health conditions. In many cases, one can just leave the blister alone and it will heal with basic care. It is important not to puncture the blister. If a blister gets worse, does not heal, or becomes discolored, it is suggested that you see a qualified podiatrist for proper diagnosis and treatment.


Blisters are prone to making everyday activities extremely uncomfortable. If your feet are hurting, contact Dr. Mark Spier of Maryland. Our doctor can provide the care you need to keep you pain-free and on your feet.

Foot Blisters

Foot blisters develop as a result of constantly wearing tight or ill-fitting footwear. This happens due to the constant rubbing from the shoe, which can often 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.

How Do Blisters Form?

Blisters on the feet are often the result of constant friction of skin and material, usually by shoe rubbing. Walking in sandals, boots, or shoes that don’t fit properly for long periods of time can result in a blister. Having consistent foot moisture and humidity can easily lead to blister formation.

Prevention & Treatment

It is important to properly care for the affected area in order to prevent infection and ease the pain. Do not lance the blister and use a Band-Aid to provide pain relief. Also, be sure to keep your feet dry and wear proper fitting shoes. If you see blood or pus in a blister, seek assistance from a podiatrist.
