Granted, it was the colorway (green on green) that first caught my eye, but the description and reviews hooked me. Although running on the treadmill isn't my first choice for daily exercise (mostly in-gym cardio routines and weightwork for me), I still generally buy running shoes for all my training, as they tend to provide the best options for my foot mechanics (a supinator, with feet that roll outward). The NB 3090s work really well for me; they're super-lightweight and flexible, and the padding is definitely adequate for my needs (I'm very small, and work out on a carpeted floor). I honestly don't know if I would like running in them (and haven't tried that yet), but they definitely get a thumbs up from me for cardio-kickboxing and HIIT routines. :)
