I can't speak from experience regarding most of the asian manufactured stuff, except for Rocky Boots. They were great when they were made in the US, in Nelsonville, Ohio, where I attended college, and could buy 2nds for a great price. I purchased them into the timeframe they moved production to China. That was the last pair I bought, the soles wore away quickly after two hunting seasons.
I did buy a pair of Silvas that are made in China, have had 4 seasons of light use on them, very comfortable, Vibram soles (have been good for tromping around after grouse in northern Wisconsin).
I like decent boots. I do like Irish Setter/ Redwings, on a personal note. Hard to enjoy a good hunt with uncomfortable feet.
A friend told me about an online source, "Zips"? or Zipps?, might be worth a look.
