All their socks are marketed as suitable for sizes 8-12. I am a size 8.5 and feel the socks are a bit too large. They really should consider breaking up the sizing. Possibly 7-10 and 10-13. Just a suggestion.
Socks either fit a size 8 or a size 13. Not both. But most sock makers think they do. The boardroom socks fit a size 10 perfectly and the quality is better than other socks that cost a lot more.
I ordered some socks a year or two ago, and liked them enough that I ordered more. Last time I bought solid-color wool-blend socks; this time I ordered the socks with dots. The first batch is confortable, holding up well, and softened a little with washing. This second batch is comfy also, but I haven't washed them often enough to know how well they'll soften up. I'm very happy with the socks.
Overall experience with Boardroom socks has been pretty good. The items were delivered on time and are of good quality. The only thing that may be slightly off is the texture - it's does not feel soft to touch.
