Looking at my kit and how it performed last Winter, I think the major weak point is the boots.
Up to now I have been using Neoprene Muckboots over thick and thin layered wool socks, but it is usually the soles that let the system down and there is just no room for an extra insole.
I've been looking at Pac Boots but their availability is fairly limited over here, the main brand that seems to be available is Seeland and I've been looking at their Snow Kings.

Does anyone have any experience of these boots?
I'm particularly interested in whether the felt sole is removable or whether there is room to add an insole that is.
