I ordered these shoes for my daughter.  Knowing mizuno's run small, I ordered a half-size larger, but even those were a bit too small.  I will be sending these back.  I would have just exchanged them for the next half-size, but that wasn't an option available to me.  I recommend ordering a full size larger than your normal shoe size.  I also looked at just placing a new order, but the pricing had gone up by $5 so I will look at other options now.
