After seeing a comment that these are not genuine, I thought I would do some research on the government assists publishing website which lists all NATO stock numbers for military contract clothing, and also cross referenced with other NSN databases. 8440-99-130-5787 (as per product image) is the correct stock number for these and it corresponds to the previous generation sock, as socks are now three sizes not a one size. The ISO 9001 mentioned by another is also correct but corresponds to the quality management system used by defense contracts.
Current versions are under the pcs system:
8440-99-908-8241
8440-99-908-8242
8440-99-908-8243

The socks themselves are robust and warm. The quality is as expected this era of kit. There are a few loose threads but they can be woven back into the fabric. It does the job but bells and whistles are absent - there are no special technical names or fibres - just a sock designed for a purpose.
The fit is slightly long on the toes as they are one size and I am a 9. They stay put when inside my boots and haven’t made my boots feel too snug.
I use these for my current roll where I can be in my boots for 12+ hours. They can get a bit sweaty in the warm weather but I have never experienced blisters from them and my feet don’t feel uncomfortable in cooler weather. I haven’t had the black version very long but I have used the green version since being a cadet in the early 2000s
Overall, considering both green and black pairs that I own, theses are a good sock for longer days in the boots where you need a cheap robust sock that isn’t going to be a loss if they get damaged at work.
