Thanks guys, just as I expected - if they were good all of us would be using them and we'd all know about it.
I agree on the base layer of silk and then wool or fleece socks in insulated boots although I'm going to give the styrofoam inserts a try just for the heck of it. Errr, that is, when it gets below 55 or 60! Oh wait, we won't see that temp until spring.
Good shootin' to you all.
