I will give half a vote for red-wings. Some models/parts are NOT USA made, but some are.
My local dealer gives me EXCELLENT customer service, good prices, and is right around the corner in town. That's luck of the draw, though.
Currently wearing red-wings. I have a 8" steel toe boot, american, and the sole is almost smooth, but I've the pair for 2 full years now and wear them every other day. My other pair is a 6" steel toe, american that I've had since about august. They are wearing well.
One time I bought a pair of chinese red-wings from my dealer. They were the only boots that fit at the time. He had to take them back in 3 months under warranty. The second pair (free of charge), came back in 3 months for the opposite seam splitting out (all whilst the american made ones were eating the punishment like candy). When the chinese ones came back the second time, he refused to give me another pair and said he will A) let me walk out of the store empty handed, or B) have the american made ones on my feet. So I picked out the 6" ones, where we went through about 10 pairs to properly fit them. He charged me the price difference between the chinese and american, so they only cost me about $45.
At first the heel structure didn't want to break in, so he worked them with his hands and told me to do so. Haven't had a problem since. Friday, I went in expecting to pay for some laces (since I burn laces, being a welder). Got 2 sets of laces for each of my boots free of charge.
Red-wing might not have the exact boot you're looking for, with the height, features, etc, but they are a good boot as long as you only buy the American made ones. For me, when it comes down to it, price isn't much of an object unless it's absurd. The comfort and safety of my feet is worth the price, and I hope you guys feel the same.
Why don't you buy cheap brake lines? Why not buy crappy oil and spark plugs? Because it'll give you problems...
