How Blisters Form on the Feet

Blisters on the feet develop when repeated friction or pressure causes the outer layer of skin to separate from the underlying layers, allowing fluid to collect in the space between. This clear fluid cushions the damaged tissue and protects it as it heals. Wearing shoes that are too tight or lack adequate support can cause blisters on the toes, heels, or sides of the feet. Excess moisture, long-distance walking, and high-friction activities can also contribute. Sometimes, blisters form due to burns, allergic reactions, or infections that affect the skin on the feet. A podiatrist can evaluate the cause, drain painful or infected blisters under sterile conditions, and recommend protective footwear or custom padding to prevent recurrence. If you have a painful or infected blister on your foot, it is suggested that you promptly schedule an appointment with a podiatrist for a diagnosis and safe treatment options.

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.
