To put it simply: Dealing with blisters is an actual pain. If you’re reading this, you probably already know that blisters are those red, raised areas that look like bubbles and occur mostly on the feet for us runners. Located on the upper layer of skin, they often fill with fluid and may also hurt or itch.
Many runners incur them during races, especially marathons, due to prolonged friction between your skin and sock or shoe. But blisters can pop up at any time, including during training runs, and non-running footwear can be to blame as well.

While most blisters don’t pose a serious health risk, they shouldn’t be taken lightly. A painful blister can sideline a runner — or worse, get infected, especially if you use an unsanitary needle to pop it. Here’s a complete guide for blister treatment and the best products for first aid and prevention.
Common Causes of Blisters
Friction leads to annoying, painful blisters. The culprits are usually our socks, shoes, or both rubbing against our skin. Anything that intensifies rubbing can start a blister, including a faster pace, poor-fitting shoes, and foot abnormalities, such as bunions, heel spurs, and hammertoes. Heat and moisture intensify friction by causing your feet to swell.
Blisters commonly pop up during races or long runs when mileage is increased and friction occurs without intervention. Your body responds to this friction by producing fluid, which builds up beneath the skin that’s being rubbed.
