Blisters form when friction, heat, or moisture causes the upper layers of skin to separate, filling the space with fluid. Some people are more prone to blisters due to skin sensitivity, foot shape, or certain medical conditions that make skin fragile. Wearing shoes that rub, fit poorly, or trap sweat increases the risk, as does going sockless or wearing socks that do not wick moisture. High-impact or repetitive activities, such as running or hiking, can also trigger blisters, especially in warm or damp conditions. Prevention often starts with well-fitted shoes, moisture-wicking socks, and protective padding in friction-prone areas. Applying lubricants or blister prevention patches before activity can help as well. If blisters keep forming or become painful, it is suggested that you see a chiropodist for a diagnosis and appropriate treatment.
Blisters can usually be treated at home, however, if you have recurring blisters or experience significant discomfort or pain, please consult with one of the chiropodists from Complete Family Footcare & Therapy. Our clinicians 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.
