I bought these shoes for the lightweight feature. Unfortunately it does not have enough cushion for road run but they are great for the treadmill. It does not feel like it's enough shoe for anything more than the treadmill. Tried it on the track but that did not work well either, there's something lacking in it for everything except the treadmill. Good thing is, since I only use it on the machine, it's lasting a really long time. I have to add that I am an overpronator so that may be why my use is limited.
