I've been using the NZ for awhile as a trainer, and I like it. I mostly like the fit (I have a narrow foot and like a shoe that fits snugly around my arches, so my foot doesn't slide around), and not being much of a heel striker the funny shape of the rear sole doesn't come into play. At around 145 and a neutral runner, I like a well cushioned, fairly lightweight trainer for putting in the long miles. The Shox NZ just seems to work for me. I wouldn't race in it...I prefer my Mizuno Phantoms for all distances, but it's a decent trainer, especially if it's on sale.
