Just got Zoom Vapor Fly for 30% off $89 and tried them on treadmill along with Zoom All Outs, with HIIT running
* Zoom Vapor Fly (non-4%) is heavier than adidas Boost, and is as stable as Boost. No ankle rolling nor instability.
* Zoom Vapor fly has definitely more cushion than adidas Boost as my knee pain did not happen after running in that
* Zoom All Out has a problem for heel-toe transition..... due to toe part being foam, mid foot part being Zoom bag and the Zoom bag Wall is stiff.
* Zoom All Out cushioning is better than Zoom Vapor Fly, as my heel & midfoot lands first..... but inner heel has a rolling motion.
* BTW I have tried Vapormax Plus on treadmill before. Best cushion ever, but lack of lateral support.
Should I return the Zoom All Out in favor of Zoom Fly?
I run both high intensity (5mph & 9mph) and normal jogging (5mph for 50 minutes).
Which sneaker would do the better job?
