Lacrosse Alpha Burlys early, Schnees when colder, always poly liner sox and wool, medium to heavy, depending on temps.
I'm not a neoprene fan any more. I have a pair of Arctic Muck Boots which are super comfortable, very warm so not for mild weather, BUT I haven't worn them too much in the woods, but the rips and nicks in the neoprene uppers are discouraging. We've got fairly thick cover here with lots of little bushes, dead sticks, etc. maybe those boots are for marshy, grassy areas only. All rubber only for me or RBLT's(Schnees or LLB).
