Really snug, but not uncomfortable
Size: Large, Color: Black
I don't know why these were so much tighter than all the other UA socks I've bought over the years. Not uncomfortable, just really tight when putting them on.

Leg part is TIGHT
Size: X-Large, Color: Black
I am a size 15, and the foot portion is comfortable enough, but the fit of the leg portion is so exceedingly tight that I can't wear them for long, which makes them worthless. I would return them if I didn't already toss the packaging.
