These are the most comfortable running (or any other kind of shoe for that matter) shoe that I have ever owned.  This is my second pair and they fit my feet great.  I have slightly wide feet and they are good for that.  I also have a pretty neutral foot strike and they also have been really good there.  My first pair didn't last super long, but I ended up playing a full season of basketball in them (on top of my running) and I think that really beat them up.  So, I'm not sure what kind of longevity they have if you are just running in them and not abusing them like it did.  They are feel pretty light and it feels like you are running on pillows.
