Run in every Wave Inspire since the original. The 10 is by far the worst out off all of them.  The shoe is so stripped down it feels like I'm running barefoot, and the balls of my feet are on fire after two miles.  The stack height on the shoe, both forefoot and heel, is reduced from the 9.  The 9 had just barely enough forefoot cushion to get by for 1/2 marys (but no more), but these are just totally useless for anything more than running to the end of the driveway to get the mail.  I don't think I've ever been angry after running in a shoe before but Mizuno has screwed this one up.
