When friction from a shoe or sock rubbing against your skin causes the epidermis (top) layer and dermis (underlying) layer of skin to move in opposite directions, the skin becomes irritated, red, and inflamed. Continued friction will cause the epidermis and dermis to separate and fill with fluid or blood, and a blister is formed. Pain from a blister is caused when nerves are stimulated by the fluid. You can help stop blisters from occurring by wearing shoes that fit properly and don’t allow your feet to slip around or rub against them. New shoes or boots should be worn in properly and gradually—before wearing them all day. If you are planning a long walk or hike, you can try taping areas on the foot that are prone to blisters such as the back of the heel, the big toe and the little toe. A podiatrist can show you how to tape your feet properly and also create custom orthotics designed specifically to keep your feet from developing blisters. They can even suggest appropriate footwear for walking and running.
Blisters are prone to making everyday activities extremely uncomfortable. If your feet are hurting, contact the foot specialists of NYC Foot & Ankle Center. Our doctors can provide the care you need to keep you pain-free and on your feet.
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.
