You will love your boots 10X more if you break them in by running in them, truck through mud and water and crap with them, clean them with soap and water, remove the soles and leave them out to dry. Only after they have shrunk a half size and fit your foot absolutely pefect would I but waterproofer and protectant on them. My OCS boots which never got anything but trashed and left out to dry are the most awesome fitting boots I own. I treated a new pair of jungles right when I got them, and they never have broken in and fit as well as my OCS boots.
