I have been selling Red Wing boots as well as other brands for years. I hear people every day saying that the boots are not as good as they used to be. In all honesty this is actually true and not true at the same time. 30 years ago, most shoes had a solid sole made out of 1 material and stitched to the shoe with a physical connection (called a Goodyear Welt) As the generation that wore these shoes has retired and hopefully enjoying some well deserved expedition travel and the younger generation that is taking over is used to wearing tennis shoes and such and demands a softer more flexible work shoe. A shoe is kind of like a tire, a tough hard tire will take al kinds of abuse but doesn't especially do great on a 1000 mile highway trip. Likewise a soft sole will have less weight and give a much softer feel and comfort but will wear down quicker. A harder sole will wear longer but will be harder on the feet and harder to break in.
As for Red Wing. They are a Family owned American company and one of the few that will actually repair and rework shoes in house. They can resole the Supersole and supersole 2.0 shoes on the same equipment they were originally built on. One note here, they can't resole new safety toe shoes but canresole them after wearing for a short while. AlsoSupersoles can't be resoled if you have worn a hole all the way through the midsole.
I also like Justin boots. They are now one of the largest domestic manufacturers of work boots. Enjoy.
