Excellent socks and warm. Your feet don't sweat easily, but if they do, they dry quickly. They are thick socks, I recommend them more for boots although I didn't have a problem with sneakers either.

I bought the codes 2062-2065 from this specific company, and after a few weeks of use, I realized that they have no durability in my everyday life.
The sock with code 2065 makes you sweat excessively when wearing mountaineering boots during walking, and as soon as you make the mistake of standing in the cold for a while, your feet freeze due to the accumulation of moisture caused by foot sweat inside the sock.
The sock with code 2062, with a thinner knit, does not have this problem. It works better in similar conditions, and you sweat noticeably less, if at all. However, it also has the same behavior - as soon as you stand, your feet get equally cold.
Furthermore, despite following the product's care instructions, I found that the thick sock, 2065, has developed pilling from the first wash, and the 2062, after wearing it only three times, has whitened on the heel and toes.
I have the impression that they need to reconsider certain aspects of their thermal sock composition. For me, success would be a composition of 100% merino wool and terry knit throughout the sock, with no shrinkage in the wash, etc.

a nice thick sock but that's about it... thermal? Not even close... in ten degrees with humidity in athletic shoes, you could feel the cold on your toes.

I would spend the money for such a nice feeling sock... as for durability, only time will tell... but as for the thermal aspect that I bought it for... no way

"Pleasant surprise" was the first feeling.
I had bought thermal socks from other brands without seeing these ones, at first I was a little hesitant but then I felt very different.
Tight "bound" with satisfactory thickness without slipping, they don't "burn" your feet and cause problems like fungus on your toes.
They are not knee-high but a little lower, however, with boots and winter pants, no problem.
I bought a set of three but after the first impressions, I will buy more at the first opportunity, it's a waste of time buying more expensive ones.
P.S: I used them for walking and indoors-outdoors at work, there was no hard test like hiking.
