Quick Answer
Blisters on long hikes are usually caused by friction between the skin and the shoe or hiking boot, often due to poorly fitting footwear or inadequate socks. This friction can rub against the skin, creating pressure points that eventually break skin cells and form a blister.
Causes of Blisters
Friction is the primary cause of blisters on long hikes. When your foot slides back and forth inside your shoe, it creates a repetitive motion that can irritate the skin, leading to friction heat. This heat breaks down the skin cells, causing them to separate and form a blister. Wearing shoes that are too tight or too loose can exacerbate this issue.
Prevention Techniques
To prevent blisters, it’s essential to wear properly fitted hiking shoes or boots, with a snug but not constricting fit. Make sure to break in new shoes before embarking on a long hike. Additionally, wear moisture-wicking socks to keep your feet dry and reduce friction. Consider using blister prevention products, such as toe caps or blister shields, to add extra cushioning and protection to high-friction areas.
Treating Blisters
If you do develop a blister, don’t pop it. Instead, apply a bandage or moleskin to protect the blister from further friction. You can also use a hydrocolloid dressing to promote healing and reduce pressure. To prevent infection, keep the blister clean and dry, and avoid sharing foot care tools or equipment with others. If the blister becomes severely painful or infected, seek medical attention.
