I've been playing in the leaves outside all day in my neon yellow M40s, and they kept me nice and warm while also looking quite adorable (if I do say so myself) paired with a black sweater & skirt. I was able to comfortably pull them up the entire length of my legs and then some. I didn't have any trouble keeping them up when I had the top ribbing folded down to about mid-thigh, even when I was leaping into giant piles of leaves in the neighbor's yard ;) My toes even had plenty of wiggle room in the feet. I think they're best described as a warm, fluffy comfort sock.

I'm SO happy with the M40s. Neon yellow is a color I'd normally think twice about getting, but it's absolutely gorgeous and you're guaranteed to turn heads in them.
