Diamond steath/z1 better than unaweep/z2
I had a pair of unaweep z2's before these. I have to say I am happier with these z1's. They are just as stable (the toe strap on the z2 is more for style imo) and the diamond stealth sole is just plain awesome. I was afraid it would be REALLY soft and wear down after a few weeks of pavement walking, but that has not been the case.
