Knot, I have a pair of Z2s and ZX2s and I love them...but it was 47 degrees out today I have run in them in the summer and they're great!

Jen, I like the orthotics - I am used to them, but the orthotics in combination with stability/motion control shoes give me massive blisters. I can only take one or the other. They help if I have to walk but make next to no difference when I run. But since I'm doing a lot of walking with the running now, I'll probably keep them.

And Yellow - I have (so far) out-shoed two running store chains here, neither of which had them on the display wall. I'm not sure where to head next. Besides Google.
