Please first notice that some 5 stars reviewrs here has only 1 review in their record (Mizuno workers?).

No improvement over the Prophecy 1. The same *cheap* stiff plastic struts for the wave. A dense rubber would be a much better implementation IMO.
Fit didn't improve either. Cushion decreased significantly after a month. Totally seems like Mizuno workers post reviews in order to increase sales.

I found the asics kinsei 4.0 much better, it's like day and night. Asics actually put much effort in order to improve each generation, mizuno just rides on the "wave" issue like it's gonna last forever (while they keep implement it with cheap hell-stiff plastic for YEARS, without any effort to change & improve the material. Only cosmetic changes over the years).

UPDATE: I've just seen the video regarding the upcoming Prophecy 3. Mizuno workers actually read my reviews, since I'm the sole reviewer to comment regarding their cheap strusts and FINALLY after probably 10 years - Prophecy 3 has improved the struts to difference material and wider construction. My harsh review probably did some good, they have been WAYYYY too sluggish with the Prophecy 2.
