Looks like an "Evo" style of Tracer or something. Probably see it out soon.
Walmsley wore the Evo Mafate at Western States. I guess he should be DQed because it wasn't officially released yet.
Need to take back Michael Johnson's medals. I don't think you could buy those gold shoes in stores.
(the weirdo OP will probably come back with WS is not IAAF and Johnson was before the current rules)
