I purchased this shoe looking for something that would encourage more of mid-foot strike but still provide cushioning for longer runs.  I was coming from the Saucony ProGrid 3 and the differences in heel to toe drop and weight are very noticeable.  Even with the differences, I didn't have any trouble adjusting to this shoe, and I switch back and forth for my runs.  At first I was a little worried about longer runs in this shoe, but I finished a half-marathon with no problems.  The lighter weight is actually nice on the longer runs and it feels a little faster than my other Sauconys.  I can't say this shoe has really helped me land any differently, but if you are looking for something a little more lightweight that still provides decent support this is a good shoe.  I've put about 100 miles on these and they are still holding up well.
