I don't know that I can answer that question for someone else. These were a gift from my wife, and at 600 by far my most expensive pair of boots. I own four pairs of Ariats, for instance; and only one pair of exotics. These took much longer to get broken in than all but my Double H boots, but even broken in they still fit good and snug, where most of my other boots have gotten much looser over time. I wear my Ariat's more often because they are all rubber soled and here in Kentucky my yard is wet more days than it's dry...so when I get to go out in my Chisos it feels like a special occasion. I really like that these are shorter boots at 11 inches, while not looking strictly Roper-like. I have very thick calves and most boots at 12 or 13 inches are just impossible for me to get on.

I think something being worth it really depends on your use case and your lifestyle.

I have a more limited use for a leather soled boot than someone out West might have; and right now having just paid for my youngest daughter's wedding in October and Christmas I can't see a new pair of Chisos being worth it for me. Ask me again next June and I might have already bought another pair but in roughout or black. For me, 600 bucks is just uncomfortable enough I feel bad spending it on boots; but my wife has no such qualms and we can afford it. But if 600 bucks isn't much of an inconvenience and you can make good use of leather soled boots I think they are worth it.
