Causes and Risks of Blisters on the Feet

Foot blisters form when friction or pressure causes the outer layers of the skin to separate, leading to the formation of a small pocket of fluid. This often happens from wearing shoes that do not fit or from excessive walking or running, increasing the likelihood of skin irritation. Blisters act as the body’s natural defense, protecting the underlying skin while it heals. Wearing shoes that are too tight, damp socks, or having an irregular foot shape can increase the risk of blisters. While most blisters heal on their own, recurrent or painful blisters may signal an underlying issue. A podiatrist can prescribe custom orthotics or recommend footwear changes that can help to prevent further occurrences. For those with conditions like diabetes, a podiatrist’s guidance is especially important to prevent infections and ward off more serious complications. If you frequently have blisters on your feet, it is suggested that you schedule an appointment with a podiatrist to find out why.

Blisters are prone to making everyday activities extremely uncomfortable. If your feet are hurting, contact Scott Samera, DPM of Samera / Foot + Ankle. 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.
