She didn't have any magical advice, just use your leg muscles to hold the leg in line over the 2nd, 3rd toes. Also, both legs should be equal distance from top tube.

I know what you mean, my mental checklist is soooo long! And I've got to say, my knee is pretty low on the list right now.

The BG fitters at the lbs put a shim in the big toe/under ball of foot area under insole of my new road shoes. They were the first to point out that my right knee was flopping around like a fish out of water! I think it has really helped. As the PT pointed out to me, the lbs guys try to stop the flopping, her job is to teach me how to use muscles to fix the problem.
