I personally would love to have a magic bullet that would prevent me from ever stubbing my toe.

I bought these shoes with reinforced toes. They're some sort of composite material rather than steel, so security checkpoints don't flip out too much, and no laces so they're easy to put on. Carolina makes 'em, for construction workers I think, but I wear them pretty much all the time, unless I'm sleeping or sitting in one place for hours. The only significant drawback I can think of is that eventually sweat accumulates. I suppose fashion might also be a problem, but valuing fashion over practicalities like mobility seems like a bad sign.
