Okay, first day with this shoe and it's already very comfortable. If breaking it in is going to make it even better then I am extremely happy.  Excellent cushioning in heel and midsole.  I was looking for a shoe that would ease the pounding of running on pavement and this one does it. I can very perceptibly feel the cushioning absorb things and make it easier to just run.  Very stable and fits my foot like a glove. I have normal arches, but after my last shoes left my left foot hurting, I feel like maybe the arch could be a little higher like the Nimbus.  That said, I think the problem is probably just my foot and after running in this much better shoe for a while I think my arches are going to feel better.  Look for an update after I have logged some miles on this shoe. Thus far, it is wonderful.
