Ran in the ZF today. 800 runner dude was right. This older pair of ZF is definitely firmer than a new pair of 4% and probably a slightly used pair too. I missed the relative squishiness of 4% the first time around because its all in the heel. I don't heel strike so I hadn't noticed.
800 runner dude is right. ZF is much worse than the VF. I tried both. ZF cushion is very hard and the shoe has no flex. It's like running in stability shoes. VF, on the other hand, is the best shoe ever.
I'm not a Swoosh shill. If I were, I'd probably say the ZF was terrific for training. It isn't.
I went through a couple pairs of the ZF and liked them; recently got a new pair and they're sooooo stiff I switched off them. Weird. Less likely the shoe changed then something in my foot is aggravated, but still, for me now it's much too stiff a shoe.
I also had a pair of the VFs, which i had planned to use in a marathon. Soooo squishy for me I returned them.
So for me, a total goldilocks, I'm back to the Boston/Adios dyad. I run as fast in my Bostons as in my ZFs...don't think it's the shoe for me (though perhaps the light weight of each helps).
