For those days you don't feel bright, endūr has an awesome selection of neutral colours too! Love the tab on the back of the socks to help grip and pull on.
Best part about these (other than the slick colours) is that the little flap on the back helps them stay up above your shoe. Haven't had an issue with my socks slipping off!
Got a few pairs of these for road running. Very comfy and I don’t notice them when I have them on.
