For feet, you might try a very thin silk sock, then a thinnish wool sock, then, on the outside, neoprene shoe covers that go up your ankle, with a wind & waterproof thin shoe cover over that. I find that works pretty well. I also try to remember to actively wiggle my toes and lighten up on the balls of my feet regularly, from the start, to keep circulation going.
For hands, I'll wear silk glove liners, neoprene gloves, and wind/water proof outter glove covers.
The glove covers I found were PI. Naturally, they don't make a women's version
, but the men's small size was still huge enough to cover the big neoprene gloves.
