OK. Took the shoes for a spin. Maybe is placebo effect voodoo, but they totally worked. Was supposed to do 36k with 20k race pace, but the shoes felt so good I ended up doing 36k with 29k at faster than race pace. Wasn't really trying to push the pace, but in the end, believe it or not my average pave ended up at 4% (!!) faster than target.
Was going to round up the run to do 42k just for fun but didn't want to wear out the shoes
(someone actually yelled at me on the run that I was wearing them too much for training!)...I did actually notice some unusual wear after the run. Have to do some research, but looks like the magic ZoomX foam is a yellow PU type foam that is painted white, instead of the typical EVA type. A bit of paint is peeling off the midsole at the heel where it wears...hmm.
Real test of course will be marathon in 2 weeks, but if anything close to my experience on that long run, I expect them to live up to the hype and more!
