Couldn't it be in English: 'the captain uses boots'? does it have to be "wears"?
it's the way people say it in English, the most common one, for anything you "wear" (use) on yourself. "I used to wear my hair longer".
He could be using boots in a different context than wearing, as in: "Any normal person would use worms or something else edible as food, but this retarded captain uses boots as bait." So I'd argue that "use" should be accepted.
