Not as supportive as expected
Size: Large, Color: Multicolor
I had expected a more fitted and supportive sock. These were replacing some older ones that apparently UA doesn't make anymore. Next time I will look into a more running specific brand. After wearing them a bit more, the fit is loose, there isn't much compression or support, and the light gray looks unclean. They are soft, but that's about it.

Great socks
My husband will only wear 100% cotton socks none of the spandex moisture control etc so these are hard to find in stores but he loves them and they last a while
