I have a pair of Nike Romaleos. I wouldn't even consider squatting in anything but. They even saved my bacon in Vegas at the WPC Worlds. We had to squat on convention floor carpeting. They provided the stability I needed to nail my 2nd and 3rd attempts. I did get a strain in my right quad, but it could have been alot worse.
At my Oly lifting course I took last year, all the guys approved off them, including the Oly Coach.
