Anyone who has walked a long distance in brand new shoes has probably encountered a blister or two. Blisters on the feet often form when shoes are too tight, socks are too thin, and feet are too moist. The main cause of a blister is friction. The skin on the feet can be irritated by rubbing against the inside of a shoe. This causes a reaction from the body to protect itself. The top layer of skin separates from the rest and allows serum to collect underneath, forming a cushion between the layers. Pain from a blister can be prevented by implementing a few easy measures. Changing the shoes to a wider toe box will allow the toes to move freely. If you plan to take a long walk or to exercise, try wearing socks with a double layer that helps provide ample cushioning. Antiperspirant foot sprays can help to keep excessive moisture from building up inside the shoes. Runners who are prone to developing blisters may wish to try using low friction insoles in their shoes. Finally, choose footwear which is made of more flexible materials to reduce friction. If you have developed a blister that will not heal, or if a blister has become infected, it is suggested that you make an appointment with a podiatrist for an evaluation and 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.
