The Mickey mouse boots are the only boots that Ive used where my feet didnt get cold. I have 1000grm Rockys w/ Gortex which arent bad. Nothing compares to the Mickeys though. The do suck for hikiing so if you walk alot they arent good.
Dont buy the Sportsmans guide re-makes of them. They arent the same. Ive had 3 different Sportsman guide brand boots and all have been junk.
I think nothing ruins hunting more than cold feet. It makes me fidget and just become miserable. Ive never tried using the hand warmers inboots or those huge boot blankets though. One looks like itll be uncomfortable and one looks way to bulky to carry into the woods.
