Peachtree's 1st place needs to be re-awarded to Aliphine.
Unless someone can find Stephanie's shoes in the current or previous Hoka catalog, I believe they are some kind of updated variant on the never-released Hoka Carbon Rocket which like the Vaporfly and the new Brooks contain a shaped carbon leaf spring layered between the foam.
So while Rule 143 had language removed banning wheels and springs and we can depressingly argue and disagree about that all you want, you cannot argue about this language in the June 2018 ratified version:
Rule changes as of June 2018
Rule 143: Clothing, shoes and athlete bibs
- Any type of shoe used must be reasonably available to all in the spirit of the universality of athletics. Shoes must not be constructed so as to give athletes any unfair assistance or advantage.
Stephanie's shoes are not "reasonably available to all" in fact they are not available to anyone else. Even Aliphine was wearing stock Hoka Tracers.
It's interesting to note that Desiree Linden barely escaped the June 2018 Rule 143 when she used Brooks carbon spring prototypes for Boston Marathon in April. A month later Desi should be disqualified. Now Brooks is rushing them into production and has started distribution to their sponsored runners - but public still can't buy them so that's also a Rule 143 violation every time their pros race in them.
Additionally, athletes like Molly Huddle, another elite I greatly admire, runs in custom prototype non-production shoes from Saucony (a hybrid of their Type A and Fastwitch models) now risk the same disqualification in future races because those shoe are not "reasonably available to all".
So Nike, who has now poisoned the running world with leaf springs in the vaporfly and zoomfly, escapes punishment because those are production models and despite the high price tag, skirt the rule by being "reasonably available" if you have enough income to buy them (btw average east african income is $800 per YEAR). All the prototypes they gave their athletes like Shalane in 2016 beat the rules since the "wheels and springs" language was removed - makes you wonder who is writing these rules or whispering in the ear of those who do.
for reference, this is the men's Hoka Carbon Rocket they only displayed once at a trade show in 2016
Stephanie's shoes can be easily seen from all the Peachtree race video and in endless photos afterwards like this twitter .com/ajc/status/1014472738734575616
