Aren't those wrestling shoes you're wearing in your avi? Lol
I've tried wrestling shoes on a few times, but could never bring myself to get a pair. They just don't feel right compared to other shoes I've squatted in. Like you said, it felt like my feet would roll...which I guess is kind of weird since I've been squatting barefoot for the last year and a half or so.
I have switched to Romaleos and really like them. Things just feel "right" in them and they are by far the most stable shoe I've ever squatted in.
The Adidas Power Lift might be a good choice for someone that wants any Oly style shoe but doesn't want to blow like $200 on a pair. I know a few guys that have them, like them, and were able to get them for less than the $80 list price.
