I am very happy with this purchase!  I have always been a big Adidas fan so I wanted to see what the hype was over these shoes.  These are the first pair of shoes that I have bought that my feet are not sore at the end of a long walk/run.  They are very comfy and very light.  Plenty of wiggle room for my toes and they fit the size that they are meant to be (some other shoes like these tend to run smaller).  Maybe the only downside is that you gain about an inch in height (haha).
