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.

Having severe neuropathy in my feet and no sock could keep them warm, I decided to try these and they really helped me a lot.
They kept my feet warm and helped with blood circulation in my feet.
Excellent!

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.

They are very comfortable, fit perfectly on the foot, and do not make the foot sweat no matter how many hours you wear them. It's the first time I see socks that don't leave any fluff. The only negative is that they are expensive, like all thermal socks.

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.
