These are by far the most comfortable shoes I have owned.  The one problem that I have is that they don't last as long as Eccos that I have owned.  I think that part of the issue is that you wear them so much that you don't realize how much you are wearing them. I usually replace them once a quarter which is about right for shoes and how long they should last.  I put on a good amount walking distance on them.  For me, they are worth it.
