Too Bulky For Sz 9 Men
Mark Long
These socks are so bulky I just cannot wear them with shoes unless the shoes are a size or more too large. I only wear these around the house. The stocking part is way longer than normal.

Not Quite "40 Below"
Dane D'Arcangelo
I really do like these socks, however 40 below is a gross over exaggeration. I work outdoors and have been wearing these socks with my un-insulated boots since the weather started to cool down in October. They were very comfortable and did the trick, but once the temperature went below freezing these socks could not keep my feet warm anymore. Granted my boots are un-insulated, but socks boasting "40 Below" in the title should do fine in 30 degree (F) weather? Overall I like these socks and if they didn't call themselves "40 below" I would have given them a 4 out of 5

Great socks!

I bought two pairs of socks for my husband to wear in the barn. He said they keep his feet very warm and made in the USA. Great!

Not good.
I wore these socks for the first time the other day at a night football game. My feet were cold before the first quarter. After the game, I though I may have had frostbite, toes were frozen. The outside temperature was around 28-32 degrees and my feet were not wet. Very disappointed. Back to my old socks.

Best socks for winter
Stephen Irle
These are so soft and insulate your feet so well. These are by far the best socks to wear during the cold winter months. I think these do run a little big. The large size is a bit too large for me, (I'm size 11) so I tried a medium and it fit perfectly.
