Well, the fiance has to leave for a funeral, so I can't get a better video. I've believe I've fixed the knee caving problem. That was a video of my first attempt at widening my stance so my knees were having trouble staying out due to flexibility issues and it hurting from the PTD.
And the shoes...I've seen many a video of Arnold lifting barefoot. If I had my own gym and wasn't worried about dropping something on my foot (which I have done) I'd be lifting barefoot.
