where, outside of thrift stores, are you finding boots at these prices?

That’s actually roughly the price range to manufacture normal shoes. “The average production cost of a single pair of shoes ranges between $10 and $50. This includes materials, labor, and overhead.” https://hevashoeinc.com/how-much-does-it-cost-to-manufacture...

What you actually pay is a large multiple of that covering the taxes, shipping, sales channel, marketing, etc.

Boots and shoes are interesting because they're genuinely an area where premium materials and construction _could_ significantly improve how long they last. We're talking 1-2 years for "normal" boots and decades for $500+ boots (with re-soling) There's also a good middle ground here. I'm not saying everyone needs really expensive boots, but it nice that you can actually spend more money for higher quality rather than a horrible system on a chip that fails after a year and renders a whole product useless.

This is true of most products, actually.
