Socks are comfy but I'd classify them more as mediumweight than lightweight. That wasn't the reason for the 2 stars though: when I received, right out of the package the material was already pulling /fraying noticeably at the top of the socks. It's fine and still wearable (especially with long pants covering them) but I'm not sure how long they will last because of this. I'm glad they were a discounted purchase otherwise I would have returned them. And even discounted, if I had seen them at the store in person like this- I wouldn't have purchased. So if these are still around (not sure since they say discontinued) and you're making an online purchase- just be aware. Perhaps I just got the bottom of the barrel pair.
I ordered men's size 13. On receipt I saw that the socks were labeled Unisex XL. However, they were "two sizes too small".
Very comfortable socks and looking forward to wearing them at work.
