I have owned many Adidas running shoes.  The Adios and Adizero Bounce are my favorites but THIS shoes is so comfortable, like running on air!  The "sock" like entry is just OK, hard to not slip in and out when doing floor workouts at the gym. But for trail/road running, these are a dream!  Fit perfect...I have put roughly 200 miles on them since purchase...and they are being worn right now!  There is a threading portion on the top seam coming undone, but we shall survive!
