Blisters on the feet are fluid-filled sacs that form on the skin's surface due to friction, pressure, or irritation. These common nuisances typically occur in response to wearing ill-fitting shoes, prolonged friction from walking or running, or excessive moisture accumulation. When friction or pressure disrupts the layers of skin, the body's defense mechanism kicks in, leading to the formation of blisters. Footwear that is too tight, loose, or made of abrasive materials can easily cause blisters, especially during vigorous physical activities. Additionally, sweaty feet trapped in damp socks or shoes create a favorable environment for blister development. To prevent blisters, it is crucial to wear properly fitted, breathable shoes and moisture-wicking socks. Keep feet clean and dry, and apply lubricants or padding to areas prone to friction. If blisters do form, resist the urge to pop them, as this can increase infection risk. Instead, protect the blistered area with a clean bandage and allow it to heal naturally. If you would like more information about effective prevention techniques for foot blisters, it is suggested that you speak to a chiropodist who can provide you with the knowledge you are seeking.

Blisters can usually be treated at home, however, if you have recurring blisters or experience significant discomfort or pain, please consult with Emily Yu, B.Sc from Uptown Foot Care Clinic. Our specialist 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. 

Treatment 

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. 

Prevention

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.
