World Athletics allows athletes to race in spikes unreleased to the public. I didn't think they did, but on this weeks Coffee Club episode, they were going over the process of spike checking before races and mentioned you could wear unreleased spikes. I imagine they're wearing the same type Lex was (CC said people were literally sharing spikes because there weren't enough pairs for everyone), and if World Athletics is cool with it, I think it's fine for HS records.
Honestly though, I love OAC and L&L, so I'm not gonna change my mind anyway lmao
