Foot blisters are a common problem for hikers, runners, and other athletes. They can be painful and debilitating, and can even lead to infection. There are a number of things you can do to avoid foot blisters, including wearing the right shoes, socks, and insoles; keeping your feet dry; and breaking in your shoes gradually.
Wearing the right shoes is one of the most important things you can do to avoid foot blisters. Shoes should be well-fitting and supportive, and should provide enough room for your toes to move freely. Avoid shoes that are too tight or too loose, and make sure they are made of a breathable material, such as leather or mesh.
