vaporflys improve time on any distance compared to other running shoes. That does not mean they are superior to spikes...
Spikes are still the best shoes to run on the track with.
I could see the debate for 10k on track (mainly confort vs performance). But 5k on track is a no brainer. Just run it with spikes.
Also buying spikes and using them like once a week in a track workout will improve your running technique and the strength of your feet. So it is worth it even if you do road racing.
I was of the same opinion, but I recently did a 5k pace workout on the track in vaporflies and it felt amazing ...
I'd wear vaporflies in a time trial where you go out at a constant pace and just try to hit even splits and there isn't really a need to kick, but I'd still wear spikes in a championship/tactical 5k where you need a big last lap.
