I did a lot of research on this shoe versus the nike free run 3+. Apparently these were better so never having never tried on the free runs I bought this shoe. It is very comfortable and great for both walking and running. I also enjoy using them when I do high intensity cardio training. The only problem is that when I received this shoe was that there was some lose threading. At first it bothered me, but I like my sneakers looking a little tattered instead of brand new so I got over it quickly.
