Mizuno Wave Drive 9

As a long-time fan of the Wave Drive 8, I was really disappointed with the Wave Drive 9. Mizuno completely missed the mark with this one. The biggest downgrade is the upper material — they replaced the sturdy synthetic leather with a stretchy fabric that provides zero support in the toe area. The fit feels loose and unstable, and there’s way too much space above the toes. Even when you tighten the laces all the way, you can’t get that snug, responsive feel anymore. The outsole also feels stiffer. To make things worse, every step produces this awkward slapping sound when running — so annoying that I ended up punching extra lace holes and adding extra insoles just to reduce the noise. It helped a little, but not enough — the “clapping” sound is still there. The laces themselves feel cheaper, and the insole was ridiculously thin right from the start — after about a month it became completely useless. The grip is still decent, but it doesn’t feel quite as sharp or consistent as in the Wave Drive 8. And one last thing — the lowered sidewall design means that when you slide your foot sideways, the shoe makes an unpleasant scraping sound. It’s distracting and honestly quite annoying, especially during fast movements on court. In short: the Wave Drive 9 is a step backward from the 8. The materials and fit feel cheaper, and some design choices just don’t make sense. It’s not a terrible shoe, but definitely a disappointing successor to such a great model.
