I would say that 2020 refines the 2019 lineup with the Tempo also replacing the Turbo 2; the VF FK was intended to be superseded by the VFNAm I correct in thinking that the line up 2019 vs 2020:
Pegasus 36 = Pegasus 37
Pegasus Turbo 2 = ???
Zoom Fly 3 = Tempo Next%
Vaporfly Flyknit = ???
Vaporfly Next% = Vaporfly Next%
N/A = Alphafly Next%
Have I got it about right?
