Blisters can arise for a variety of causes. When running, they might be caused by excessive friction, wetness, and perspiration. However, blisters can occur when people do not wear socks and walk (or run) often in ill-fitting shoes, according to the Cleveland Clinic.
When this happens, the skin layers might split and the holes fill with fluid to avoid additional harm, according to podiatrist Tony Gavin to Runner’s World. According to the Cleveland Clinic, these blisters are known as friction blisters, and the fluid is clear.
Aside from friction blisters, you should be aware of two more forms of blisters: blood blisters and heat blisters. Blood blisters arise when the skin is squeezed and blood vessels are ruptured, causing blood to pool in the region and form a blister (per Cleveland Clinic). According to Healthline, these blisters might be red, black, or even dark purple. Heat blisters can also induced by sunburns, burns, or warming up after frostbite (via Cleveland Clinic).
Blisters can heal on their own, but they are more unpleasant when jogging. Fortunately, there are various methods for treating blisters for a more comfortable run. Here are some strategies for jogging with a blister.
