This, but try to make sure that you're not going to hurt it taking your boot off, I skied on a sprained ankle last year and the part that hurt the most was taking my boot off. Try pulling on your foot the way it gets pulled when you take your boot off and see how it feels.
But probably best to not ski at all. Think of it this way, you can miss one or two weekends now, or you can try to ski on it, and if it gets hurt, you'll miss the next 6 or so weeks.
