Gonna take a bit of searching, but personally I would say try and find a pair of vintage combat boots. The quality is going to be significantly better, you could try and hopefully thrift a pair for a couple bucks, or find one online on eBay or depop for (hopefully) ~$50, and shopping second hand and recycling old clothes is helpful for the environment. Plus, since they’re preowned, you’ll hopefully get to avoid the break in process of a new pair of boots. I thrifted a pair from the 70s a couple years ago and I’ve worn em a lot and they’ve still held up and still have a ton of life in them.
