The first time I ever wore the Nike Romaleos on OHP I noticed the difference immediately. My form and resistance load progressed on the spot.
I wear the shoes on every lift except Deads. I use my Chucks for deads still. Even on bench, I notice I am able to get a bit better leg/heel drive, and they keep my feet more stable and in position while I create my arch and while I bench. The shoes help all aspects of the squat, especially sitting back and of course the stability.
I think the Nike Romaleos are the best ones out there. They are not cheap of course, but worth every penny. Even when I took that Oly lifting course last year, all the lifters and the coaches agreed they are the best.
If they don't help your squat out I'll be a monkeys uncle.
As much as I love PC's, I like full cleans or squat cleans better. I found that as the weight went up, I naturally started doing full cleans. It's amazing how much heavier a 185 squat feels after cleaning it.
