I really wanted to like these shoes. I have Structure 19 and love them so much I bought 3 pairs. This new shoe looks stylish, has good support but the midfoot is a bit narrow and the sole is very, very durable. So firm that after a short walk and testing on the treadmill, my feet ached from the lack of cushioning. When I put on a newer pair of 19s I was amazed at the better feel of the sole, the cushioning but some support. If Nike had softened the rubber/midsole of this shoe a bit it would have been better. Not as soft as Pegasus, but somewhere in between Pegasus and this model.
