Running form via Newton

I am not a current Newton runner, had a pair and returned them last year due to the cost and some Morton's Neuroma in my left foot. However, this is a good overview of form and the need to have a forward lean/mid-foot/forefoot stance. I am convinced that when I am good on the form my knee hurts less.
