text: I have worn Mizuno exclusively the last 5 years and have always been a size 10.5. This shoe is much more restrictive/narrow than any Mizuno I've ever seen! Not only that but now all of a sudden my toes are much closer to the end of the shoe than previous shoes I've owned to the point where I'd probably need an 11 if I wanted these.  The plastic material they used in this Sayonara 3 is restrictive and artificially creates a more narrow shoe (especially when compared with Sayonara 2) and is a more narrow shoe to begin with so that really doesn't help. This shoe is a huge miss! Whatever they did with this model really messed with the sizing and width.
