I have to disagree with Kevin. I, myself did a test once in climb out where I picked up about 1/8 inch of ice. I wanted to see if those folks that said it doesn't make a difference when you inflate the boots. Well, I can tell you first hand, it formed a pocket and, that's right, the ice did not come of the leading edge. It took about 30 minutes of flying at 12,000 feet before it eroded and melted away. So, quite frankly I don't believe any of those people that claim you can use the boots with any thickness of ice...it's simple not true.
