I've worn many Danner boots over the decades, and will outright say the only ones worth a shit are the ones USA made. The China and other Asian produced versions are shit and fall apart with only moderate use. I'm a daily wearer of boots, when I buy a pair I go everywhere with them, and use them hard for all sorts of work and walking. I don't hesitate to spend a few hundred on a pair of boots, but when I do I expect two years out of them, minimum, and the Chinese Danners would only give me 9-12 months before stitching fell apart, soles split or separated, etc. I have a pair of Portland made Ft Lewis I bought back in '93, still wear them from time to time today, and they've seen a ton of miles while wearing out four sets of Vibram soles with not a single stitch popped. That's quality there, without a doubt.
Red Wing, same thing but to a lesser degree. I got two years off my first pair of Chinese made steel toe loggers with finally swapping out due to sole wear, they held up pretty well, but were a royal bitch to break in and took a lot of mink oil to get there. I got a second pair, same exact thing, hard to break in and nearly a whole can of mink oil into them to get them comfortable. Third pair, got the US made loggers and boy is there a difference. At least another half pound for the pair vs the Chinese versions, and you can tell that's in heavier duty leather and a denser sole. I got them home and put on the first thin coating of mink oil for water proofing of the leather, and let them dry for a few hours. I put them on to do the expected first run of breaking them in around the house, and they gave me zero pain whatsoever. They are so nice though, they're my off work wearing boots and I'll rotate them into work wear next year. You know something is comfortable when you want to wear steel toes for every day boots.
I can get Justin's for work with zero out of pocket, and I still pay for Red Wings. They're worth every penny, especially the Wisconsin made ones. A simple side by side comparison of them to the boots on my feet showed me the construction difference, it's no contest.
Made in USA. It matters in many ways, equally as important for the producer as it is the consumer.
