Ok you asked for it... Vomero 14 will have a full lenght air unit (like peg 35) and react. Zoomfly is going to be full react, flyknit and have a carbon firbe plade soon. Vaporfly 4% is going flyknit. Elite 10 and Streak 7 just have a minor upper change (thinner mesh). Peg Turbo's upper is like a plastic mesh (it is not like the peg 35 at all) and is super light (like 4%). Odessey React is going flyknit for the front of the upper. Epic React 2 is just a minor change in the upper. All shoe designs wll say what they will have in them (foam,air unit...) like the design on the Zoomfly sp.
