I've spent quite a bit of time in outdoor sports and don't think I've met a single person who did a lot of rough hiking and preferred heavy duty hiking boots over lighter trail running or approach shoes. I see quite a few of the old school heavy boots for sale in some stores so there must be a market but I have no idea what it is.
Barefoot hiking is also very niche from what I've seen, but I do think there is something undeniably nice about walking around camp or a yard in bare feet.
