I'm a bit of a connoisseur of these socks, since I wear them every day and have been ordering multiple packs for years. They start to wear thin after a year or two, but early on are typically nice and cushy. Just got 3 new packs in, the teal ones have two different color thread and when I washed them they all shrunk way more than past orders of same socks. Feels thinner. Not same quality, or I received knock-offs. Really disappointing, have to find a new go-to sock.
