My favourite socks IN THE WORLD are the Woolpower ones. I don't know what weight they are, but they're green (durr). But they're SO soft and toasty, and I get cold feet. They're not cheap either. I picked mine up in a sale, I don't think I would have bothered otherwise, but I'm glad I did. My feet are big too (UK size 12) so finding socks to fit can be tricky, and I've not found them in my size since, so I only wear them when I need them. In super cold weather they can be doubled up, under another tougher pair of Bridgedales. I use the 3 season version of them, which I like a lot too, again, not cheap, but lots of wool in them which my feet like, and they last well.
Day to day I've got an old standard pair of Stanley leather work gloves. Tough and simple, no frills, but not very insulating. As they're fairly big I can put another pair of woollen gloves on underneath. I find if I'm doing heavy work/hiking I tend to take them off after while anyway.
