they do have passable fake foams, and have for a while, once they fixed the heel shape.
the rubber on the soles isnt the same composition. looks the same. but the outsole wears MUCH faster than legit pairs.
but sz13 heads need to be safe because the fake factories finally purchased/acquired the sz13 foamposite mold. ive seen fakes in sz13 royals, all black, and the colorways from the past 6 months.
sz13 heads realize the foamstruggle. and so ya know, its no longer as safe as it was. i wouldnt trust stockx or goat to know the difference.
