you might want to do 10 min max per run in zero drop initially before going back to 12 mm for the rest of your run UNLESS you grew up in track spikes and zero drop soccer cleats (which is not that many of us).I did grow up in track spikes and still trashed my calf/Achilles going from 10mm to 6mm shoes too quickly. Damn to getting older. And I was only 30 when it started... I finally just scrapped the nike frees for anything over 4 miles and stick to Pegasus or LunarFly's. My legs are thanking me. But it feels awful dropping to flats for a road race without any speed work in them.
