Yes the white feed feet do move opposite the bar -- meaning that when the bar is going up the feet are going down and vice versa. However, the feet don't move foward at all on their own. I would have thought that as the feet move up into their highest postion they would come forward as well. Therefore, the feet continue to move up and down, they just sit at the back of the foot and do nothing to help feed the fabric (if that makes any sense).
Thanks for helping try to troubleshoot this!
