Pretty good quality for the price. I love thin socks (thick bulky socks are uncomfortable) and these are exactly what I was looking for. The color doesn't seem to bleed. I wear a size 7 and they fit fine (not sure what's up with the 9-11). They also fit my boyfriend, who suddenly needed to steal my socks, so they seem sufficiently stretchy. They don't roll down or slide down my socks into my shoes so yay!
