These are getting harder to find, as they are two models later in the design now.  But these are still my favorite.  Lite weight, comfortable, durable.  Overall, these are one of my favorite running shoes of all times.  Here is the thing though, take my rating and others as a sign of build quality, but you must try on running shoes as a runners experience is completely unique based on your foot and running stride.  These fit me and my style, and I have used them up to 30 miles at a time.  Great product.
