I was lucky enough to get these at the Boston expo in April. Actually considered running Boston in them cause they felt so good on an easy run two days before the marathon but I opted to play it safe and run in the Boston 3. I've had the adizero Boston 1, 3, 4, and now these. These are my favorite with the 3 in second. The upper is much improved from the Boston 4. The boost material is simply great, it works. Doesn't feel too soft. The shoe feels lighter than previous Boston's but no sacrifice in performance. This is my go to shoe for racing halfs and fulls, tempo runs, and marathon pace long runs. If you want a little more cushioning than the adios for racing then this is the shoe for you.
Was this a gift?:
Bottom Line Yes, I would recommend this to a friend
