The updated Mizuno Wave Horizon introduces XPOP foam for responsive cushioning in a very stable shoe. Mizuno has removed the wave plate and replaced it with their new foam wave technology that uses geometry rather than a medial post for a more cushioned shoe that is still at the pinnacle of stability. The upper has also been updated by removing overlays, which has contributed to a roomier feel. If you are a fan of the Horizon, be sure to try the new version. If you need stability with some plush cushioning, this is also a shoe to try.
