Every Mizuno conversion below is verified against the brand's official size chart.
Mizuno fit — the short version
True to size — order your usual Asics length in most models. The Wave Rider holds the midfoot secure and opens into a wider toebox than older Mizunos. The heritage fit is on the snug side, so wide feet go half a size up in the racier, lower-volume models.
