This is the first time I am wearing such a sock. Incredibly good in low temperatures, it did its job and more than that. For indoors during winter, it is just what I need!

Quite good quality and satisfactorily warm, however for people who are size ~43, I would suggest not to take size 40-43, but to go for the next size up.

I wear shoes size 42.5-43.5 (depending on the shoe etc.), I got size 40-43 in the socks and they are small for me. I do wear them, but they are not my size.

Excellent. I didn't try them in extreme conditions but in cold weather around 6-7 degrees and in athletic shoes that are not warm, they were significantly warmer than regular thick socks.

The biggest difference that really impressed me is that for the first time my feet didn't sweat at all while I was hiking all day. The feeling was amazing, just for that they are worth the extra money.

A simple sock that tightens your foot more, nothing more. In terms of warmth, it is the same as the simple sock from the same company. They shed from the first use. Personally, I would never buy them again.

At 9°c when I tried it on a motorcycle for a distance of 30 minutes, it was just fine, I wasn't cold! Nice feel, neither tight nor loose, the right height.. I got a second pair too

If this sock is thermal, then I am an alien. My feet, especially my toes, are ice cubes, so they don't work. The seams are so poorly done that if you turn the sock inside out, you'll be shocked! They are not worth it in my opinion.

Great for both cold and hot weather. You don't feel your feet getting sweaty. I use them for hiking and so far they have performed very well.

Excellent socks! I never imagined that my feet would be at a steady temperature when I wear them (constantly now!). Additionally, they give a great feeling of cleanliness and keep my feet dry because they breathe. Wonderful!

Big cold lover I was looking for a sock to keep my feet warm because even indoors my feet, due to inactivity or long standing, were becoming ice cubes!! I bought two pairs to try and as soon as I saw how warm, how VFM they are I bought another two straight away!!

They give something more than regular socks plus some special socks that I personally bought in the past, but I was definitely expecting something even better. Comfortable fit, breathes well at good levels for the foot... But I wouldn't say it warms you up to satisfactory levels. I'm not asking for crazy performance, but it didn't reach very good standards either. I'm not saying someone shouldn't buy them, but my advice is to look a little further for something better that surely exists.

It is the only sock that has left my husband COMPLETELY satisfied, whose feet have had small bruises the past two winters due to the cold. They do indeed keep his feet warm and protect them from snowstorms.

I didn't expect them to be so warm. On a 3c machine, my foot is warm. Very satisfied, I will buy more pairs!

It does its job and more at a temperature of -5, keeping the feet warm and you really don't feel any cold at all. Compared to other ones I have tried, it is of superior quality and, most importantly, it does exactly what it's supposed to do

Comfortable, warm socks with good breathability that keep the feet warm on cold days.
One of their positive aspects is the feeling after many hours of walking, as they remain dry and warm.
