There's only one surefire way to get left behind during a marathon: Wear an uncomfortable pair of underwear that keeps slipping, riding up, falling down, or chafing your poor thighs. The best women's underwear for running isn't a luxury — it's a must if you want to go the distance, compete, or beat your personal record.
For starters, they share a lot of the same features. Moisture and sweat-wicking underwear with cooling details like mesh panels are right up there among the most important features you need to keep your temperature regulated during a sweaty session. Fabrics are everything and, ideally, your running underwear will be constructed from a blend of breathable cotton, nylon, and spandex. To keep rubbing and chafing at bay, look for flat-lock seams that help the fabric lay flat against your skin. And never underestimate the power of a seamless and tagless design that keeps visible panty lines and itchy tags out of your life.
After these details are dealt with, the best underwear for running really depends on the style you prefer. This list has a little bit of everything — from the best workout thongs that are actually comfortable to high-waisted compression underwear that prevents aches and pains from getting in the way of a good run. Give your favorite sneakers a run for their money by investing in a few great pairs of underwear that will make your runs far more comfortable.
