Causes of Foot Blisters

Your feet often undergo substantial stress and strain. This constant pressure, coupled with friction from ill-fitting footwear or intense physical activities, can result in the formation of painful blisters. These fluid-filled sacs, ranging in size, can impede your ability to stand and walk comfortably. One of the most common causes of blisters on the feet is Ill-fitting shoes, whether too loose or too tight. Friction from sandals, boots, or shoes that rub against your skin may lead to the development of blisters. Likewise, shoes with a narrow toe box or excessive tightness can irritate your foot skin. A number of other factors may cause blisters to form on the feet. Engaging in strenuous activities, such as athletics, running, or hiking, can subject your feet to increased stress and friction, making them more susceptible to blister formation. Prolonged exposure to cold, even above-freezing temperatures, can freeze tissues beneath the skin, resulting in blister formation. Dampness and exposure to a chilly wind can make it worse. Diabetics, particularly those with neuropathy, may experience non-inflammatory sores resembling burn blisters that appear on the feet. Whether it's choosing proper footwear or managing underlying medical conditions, if you are having continual problems with blisters on the feet, it is suggested that you make an appointment with a chiropodist.

Blisters can usually be treated at home, however, if you have recurring blisters or experience significant discomfort or pain, please consult with Paul A. Scotti, D.Ch from West Toronto Foot & Ankle Clinic Inc. . Our chiropodist will assess your condition and provide you with quality foot and ankle treatment. 

What Is a Blister? 

A blister is a small pocket of fluid in the upper skin layers and is one of the body’s natural responses to injury or pressure. Blisters can also result from burns, fungal or viral skin infections, and the feet are particularly prone due to ill-fitting footwear and friction. Friction on the skin causes the upper layer of skin to separate from the lower layers. The space that this separation creates then becomes filled with a liquid called serum, which protects the lower layers of skin. 


If you notice a blister on your foot, you can cover it with a soft bandage or dressing to protect it. Popping the blister is discouraged. Doing so exposes the raw skin underneath it to bacteria and also raises the risk of infection. If a blister pops naturally, let it drain before covering it with a bandage. Blisters usually heal on their own or with home treatment, however, if your blister is recurring, very painful, or appears infected, it is recommended that you see a chiropodist for treatment. 


You can help to prevent blisters by wearing comfortable, well-fitted shoes. Keep your feet dry by wearing moisture-wicking socks and dust your feet with talcum powder if they tend to get sweaty. If you have areas on your feet that are more susceptible to blisters, you might be able to prevent the blister from forming by covering it with a pad.
