Pretty much already said, derek summed it up well.
All nike shoes with Zoom Air have No visible air bubble.
Zoom Vapor 9 & 9.5 for example, all have air zoom.
Any nike shoe with "Zoom" on the heel, or "air zoom" or "nike zoom" ... it's all the same thing. And it's nothing like "Air Max" which is the visible bubble and rides higher off the ground.
According to nike, the air pockets are in there, just smaller and thus lower to the ground in a "zoom air unit".
The zoom breathe 2k11 & 2k12 had it.
Vapor 4, 5 & 6 had it. (7 & 8 went to lunarlon), then back to zoom in the V9's.
Certain lines of the running, basketball, etc have it too. It's never a visible air unit like Air Max. There are some shoes that have Air Max in the heel, and Zoom Air in the forefoot. Like the old Courtballistec had lunar in the forefoot and Air Max heel, etc. So it is possible for a shoe to have both air max and zoom at the same time (although i don't think a tennis shoe has had that combo yet).
So, this will feel very similar to current Vapors, the old Breathe 2k11/2k12s, and the venerable Vapor VI line.
