It seems to be universally agreed that the 10,000m spikes are just superior to the 1500 spikes due to having a full plate, despite being called the 10k spikes all the ON pros use them down to the 800 and they feel aggressive enough for 800 / 1500 unlike the Dragonflys which are only good for 3000m and up. I just got them this season and they're easily the best spikes I've ever used, very aggressive but still comfortable and great energy return for 800 up to 5000.
Which is good for 800/1500/3000m
