This guy is famous for sawing boots in half, testing materials and doing the most indepth boot reviews you'll ever see. He teamed up with one of the best bootmakers in the US. And made a pair of boots designed for the Apocalypse.
You can also see just about every great boot ever made or boots currently in production cut in half and reviewed. Even historical military boots. In fact his design is partly inspired by the WWI military boot.
Its very addictive.
These boots are ridiculously expensive. But if you look at his channel you'll be able to pick out the best boots in your price range. And literally know why. Cause he saws them in half and shows you actually what they are made of. And how they are made.

Here's an example. The Japanese during WWII actually had a really well designed boot. To bad their guns weren't as well designed. ;)
