Yeah, I've got a pair of American made Red Wing loggers that I got for about $400 out the door that have survived 5 years of the often intensive and long hours I pull in staging. Love them to death, but they don't make the steel toe version in America anymore and you can tell the difference between the American made and the Vietnamese made ones visually.
Yeah, $600 is a hell of a lot of money, but they're American made by hand with all American materials by a smaller American company out of Spokane. I'll pay the extra fee for making sure my money goes into the hands of actual workers instead of a faceless corporation that takes advantage of those workers.
The really neat thing is, if you can wait up to a potential 35 week lead time, they'll make you an entirely custom pair of boots even if both of your feet are different sizes, exactly how you like.
ETA: These are the boots
