Broken in before you leave is not optional. Hour eight on hard ground is the test, and it is too late to fail it abroad.

The communal shower point deserves more weight than it gets. It is not comfort, it is the one hygiene situation where bare feet are a genuinely bad idea, and a flat pair weighs almost nothing.

I treat them as part of the wash kit rather than as footwear, which also stops me arguing with myself about whether they count.
