Darn Tough VermontDarn Tough Men's #1953 Mountaineering Micro Crew Extra Cushion Socks

Perfect socks. I've had them in the Himalayas, and they're warm and comfy.

Fits shoe size 9.5 perfectly, very warm and I bought from a friends recommendation who lives near canada

Brilliant, well made, warm, nice cushioning but not as thick thermal socks which means you can still fit your shoe on. True to size. I am a size 9 and got a medium.

Great comfortable fit no seam rubbing, working 12 hour days at minus 2° and feet feeling warm and dry highly recommend. Will be interesting to see how long they last, price high but will be worth it if they last.

Comfortable and don’t move in the boot. Fine weave with no irritable joins.

…They’re not going to keep your feet warm if you sitting still in a cold environment, you need to be generating body heat so that warm blood is going through your toes to keep them warm and then the socks will contain that heat creating a warm ecosystem in your boots. If you’re sedentary you’re going to need a heat source such as toe warmers or heated insoles.
