I really like these shoes, especially how they roll forward in the front.  it's like you're falling forward with each step, so you propel yourself with this momentum.  Those of you who think this shoe has some type of spring mechanism that will help launch you forward, think again.  The curved front that gives that "falling forward" feeling is all that propels you.  The fancy wave system below your foot is primarily for shock absorption for those of you who are "heal planters".

My one issue with the shoe, which is upsetting, is that the crisscrossing straps on the (front, outside) portion of the shoe.  As you look at the shoe, it looks like an "X" with one slash being that greenish-yellow color and the other slash in the "X" being the gray color.  Hopefully you see what I'm talking about.  So this "X" in the show provides a rubbing point on the inside of the shoe and places pressure on side of my foot adjacent to the ball of my foot, on the pinky-toe side.  I've thought about putting something in the shoe that will slowly spread the shoe side ways but I can't find anything, so after finally finding the Wave Prophecy 2's for $177, instead of $199, which is still way overpriced, I bought those and saw that after many complaints, Mizuno remove this "X" support point in the shoe so no more pressure.  Although, the newer 2nd edition doesn't give me that propelling forward feeling that I felt with this first edition, so I'm still debating on finding a shoe spreader to keep this first generation model.
