I have worn all 3 versions of the zoom fly. I really liked the original shoe for its weight and feel. The flyknit version was not a good fit for me, I always felt that my foot was falling out of the shoe, but I enjoyed the extra bounce it provided. This version has a great responsive feel however the upper part of the shoe, including the lacing system and extra material (second layer), seem too bulky snd hard and they push against my foot which has caused pain on longer runs. I think I would absolutely love this shoe if it had the upper of the original zoom fly. And while not as important, I wish the women's version had more color options.
