Very good! The foot doesn't sweat at all, they are a bit heavy but comfortable. I ordered them one size smaller than what I wear and they fit me perfectly, just instead of black, I received green ones

Very good construction, lightweight and durable.
Pay attention to the sizes.
I wear a 44.5 in sports shoes and I bought the size 42 which is okay with a sports sock.
They do not have lining, so you will definitely need a warm sock

Very mediocre. They are not waterproof, they collect a lot of moisture very quickly, resulting in the sock becoming wet and NOT warm at all. They are not suitable for distribution.
