these are the best shoes I have ever had, I spent the last couple years jogging in adidas supernova's and thought they were best thing.  The first of this year I was starting to get unusual hip and knee aches after my runs.  I switched to these just to try something with a little more support. When I first tried them on I thought they were very stiff and wasn't sure about them.  I have been using these for a week now and all of the pains are gone. I have even increased my miles each day and still no aches or pains following.  Love Love Love them!!!
