First off, TriVillage (the seller) shipped this extremely fast and had great communication - props.
I really like these shoes - as someone with a more neutral gate and higher arches they feel fantastic.  The are very light weight, breathe easily and provide enough cushion for longer runs (I'm 175 lbs).  I have bought Mizuno shoes for a long time, have gotten away from them in the past 4 years, but now will never buy another running shoe!
