I'm a relatively new runner... just training for my first 5K.  I went to a running store in Concord and they analyzed my stride and took impressions of my feet, etc.  I just couldn't justify spending $100+ on shoes plus $70+ on inserts though.  Luckily these shoes were the deal of the day that Sunday and so I tried them out.  They work way better than the cross training shoes I was running in.  They're very light on my feet, have much more cushioning and really let the air in the tops of the shoe.  In fact, I can feel the breeze blowing across the tops of my feet sometimes.

All in all, I'm very happy with them.
