I own this shoe, but I didn't buy it on Amazon. I enjoy the flexibility of the shoe as well as how light it is since I am transitioning to a more minimal running shoe. My only issue is that when I run on the road/concrete I tend to feel like I am slipping. That really is the only reason why I haven't given this shoe 4 or even 5 stars. It really makes running anywhere other than on the treadmill a less than enjoyable experience. Hopefully the new balance minimus shoes don't have this same problem.
