I know exactly what you mean, I have a pair of the 90/360 infrared somewhere in storage and the upper was good but unit was starting to yellow. This was so long ago so I know at this point the yellowing has gotten significantly worse.
I kinda wish that Nike would bring back the 360 and some of the hybrids that released for the one time only pack/that year. I still kick myself for not buying the foot patrol 90/360 when I had the chance. Like the 97/360s, the air max plus/360 hybrids were also one of the hybrids that were executed very well but they're extremely hard to currently find
