My current boots have 200 grams of thinsulate and my previous ones had 600 grams. I can't tell the differance warmth wise between the two. If it gets below 20 degrees or so without constant movement I break out the Schnees pack boots.
Everyone is different though. My feet get cold pretty quick.
And as the poster above mentioned try to dry your boots and socks out every night.
