I so wanted to like these shoes. I have the Structure 19 and really like them, I bought 3 pair. This new shoe looks sharp, has good support, but the midfoot is a little narrow, and the sole is very very firm. So firm that after walking around a bit and testing on treadmill, my feet hurt due to lack of shock absorption. When I put a newer pair of the 19s on, I was amazed at the better sole feel, cushion but some support. If nike made this shoes rubber / midsole slightly softer it would have been better. Not as soft as Pegasus, but somewhere between the Pegasus and this model.
