Impervious to some terrains

I think a good super power would be to know when you’re about to get a rock stuck in your shoe.  That way I could avoid walking through quarries.  Not that I walk through a lot of them to start with, but it would be a good incentive not to take up quarry-walking.

When you get a rock stuck in your shoe, you go through a few phases.  The first is, "OW FUCK!" and the second is, "I can ignore the pain using meditation and breathing practices that I've never done but have seen on TV," and the third is, "Fuck it, this is really annoying; I'm just going to sit down and get it out."
