I already knew I should order half a size up from my normal size so that was fine. My problem with these shoes is that they are not very comfortable. This is the second pair of Mizuno shoes I've bought; different models Both pairs were very robust. Because the upper is synthetic, it can feel like it's digging into you instead of moving with you if it doesn't wrinkle in the right place for your foot. Not comfortable. They seem to fit better than my first pair (Miz) so maybe they're more serviceβ¦
