I bought these hoping to solve the black sock problem.  If I liked them I was going to buy two more and have 18 pairs of perfectly matched socks.  I do this every couple years.

These were fine socks so I'm rating 4 stars.

I found them very thin and very elastic-like.  By elastic-like I mean that if I pull them on strongly, the heel will be up my leg and hang out of the shoe.  This is easy to fix, pull them on gently.  I like a little more substance in my socks, and in winter, these didn't provide much warmth.

If you like thin, light weight socks, these might be right for you.  I'll keep them for back-ups.
