At my vascular surgeon's office (at NYU Langone) they just unwrap the Unna Boot. First, they unwrap the Ace bandage on the outside. That's very easy, because it's not stuck to anything. And why waste an Ace bandage by cutting it to pieces? Next they unwrap the gauze filled up with zinc paste. This part is tricky, because the zinc paste is like glue that is hardened, and now it's stuck to itself, and the bottom layer is stuck to your leg. So if the person doing the unwrapping knows what they are doing, they will have a spray bottle filled with warm water (I think) handy, and they will first spray all the white gauze with water to get it very damp. That gets rid of the 'glue' effect. And now the gauze will be easy to unwrap from your leg. And if necessary, they will continue using the spray bottle wherever the gauze is still sticking to itself, or to your leg. That way, they don't cause you unnecessary pain, and they don't rip off the skin on your damaged leg.
