ullfrotte socks - shoe size

[Ogden]

Thinking about the next pair of shoes. Normally I wear ullfrotte knee-socks,
and now I want to buy boots for an extended trip up to 6000m.
The knee-socks are made of 600g material, and probably will not be warm
enough (?!).
1.If I choose the ullfrotte arctic socks (800g): warm enough?
2.Can I wear the knee-socks + a pair of socks, or is it bad for circulation?
3.I prefer the shoes to be very tight. Do I really need roomy shoes for 6000m
(or do I need shoes roomy enough for the thick socks, and I can still have
a tight feeling)?

Thanks+Greetings

I really wouldn't recommend ullfrotté socks at all. If you compare (warmth and lifetime) to other brands of technical wool socks, the ullfrotté ones are, more or less, crap. I assume you are planning some kind of climbing tour if your going up to 6000? Are you used to high altitudes?
Anyway, I would recommend plastic climbing shoes with liners(if you're going to climb), and smartwool or devold socks. And as always when hiking, of course, use two pairs of socks.
