Yeah, I figure they'll probably take some work. But the length probably includes the pointy-part at the front of the toe, and of course I may be wearing it over fairly big boots. So we'll see.
That's what I'm assuming, and there's a bit of "space" between the sabatons and shoes that won't sit 100% flush, so it might be close to decent in size. Depending how much extra space of opening on the top there is (if any) it might be pretty easy to trim down if necessary, since it's flat there and easy to cut.
