I have since worn them for more than 170 miles of running and walking with no discomfort or pain. They are lightweight and breathable, which has been helpful during long runs in the heat.
I love love love this lip balm. I compare it to the $24 version from Summer Fridays, which I've been splurging on - I love that brand because it lasts so long and is so high quality, but this $4 E.l.f. version feels comparable and, more excitingly, comes in smaller versions so I can stock my totes and bathroom with them whether I'm at home or on the go. It's hydrating, lightweight, doesn't get sticky, and adds a perfect ~subtle~ gloss whether I'm using it alone or on top of a lip color. I love the vanilla flavor so much, it's got a similar vibe to the birthday cake flavor that Glossier sometimes carries.
