I ordered a pair of the dark yellow socks that arrived today. They had a sticker that said they were imperfects, a fact not made known in the company's advertisement. I tried them on and found that they do not spring back into shape, but stay baggy after they are taken off. The top has a single thread holding the knitting in place, so when it goes, the sock will unravel. I don't think they will last long. You get what you pay for...and sometimes less.
