There's already a more recent thread up about this, and this is a necro from almost a year ago, so I'm going to close this thread.
But here's the devs' explanation for the lack of bloused boots options:
10. Is there anything in the game that we have been asking for that can't be added?
Some requests would unfortunately require a big overhaul of the game engine, changing our whole approach. For example, a Mission Editor. The same goes for Bloused Boots: if we could simply add it, we would! But it actually requires a huge rework of our Charactersmith, which is also something we can’t envisage right now. But, this doesn’t mean we don’t have a ton of great content coming: our time and effort is being put into something else!
