In colder weather, blisters can form on the feet due to a combination of factors related to temperature and moisture. Wearing heavy socks and shoes in the winter can lead the feet to sweat that accumulates inside your socks and shoes. This moisture, combined with reduced evaporation rates in colder temperatures, creates a damp environment around the feet. As a result, the skin becomes softer and more prone to damage from friction and rubbing against socks or shoes. Chilblains, lesions on the hands and feet that appear after exposure to the cold, can also blister. They appear within 24 hours of cold exposure and are caused by tiny blood vessels expanding too quickly once the body is exposed to heat again. If you have foot blisters after cold exposure, it is suggested you consult a podiatrist to conduct an exam and offer options to help with recurrent blister formation from chilblains. 

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 Katie Besselman, DPM of Advanced 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.

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.
