The only negative I'd give these socks is that they're a little on the stout side for a lightweight hiker. They're not super thick by any means, just thicker than I'm used to with lightweight class socks. That being said, they do wick great and so far haven't been too warm for me, I'll try to provide an update after some time in the desert this summer.
For the price they're pretty hard to beat (2 pairs for roughly the price of a single pair of merino socks from some other brands? Yes please!) . They are super comfy, seem like they're going to hold up really well, and they maintain a nice snug fit all day long. There isn't much worse than having a sloppy sock slide down into your boot or bunch up at your heel and I don't think these will ever have a problem with that.
