Weird, I had Rouge on mine, but I caught it as soon as it restocked so. Dunno if they took it down already. Honestly, this is a bad look for Balenciaga imo. Arena's are great, but people like exclusivity as obnoxious as that sounds. More pairs, lower street price, way more people wearing them. If you walk past a 14 year old in Balenciaga's, you're going to be less prone to want to wear yours, let alone buy new pairs, and that's what happened just last week. They really need to do something new.
Rouge is there, but there's no way to add sizes of it. My size in the extra white is also causing an error whenever I try to add to cart, so that's probably gone too (44). As far as exclusivity goes, these are still ridiculously expensive and relatively rare sneakers. Just because you happened to see some rich 14 year old in them doesn't mean everybody and their momma is going to be wearing Arenas now. Honestly, it just seems that they're a pretty great entry point for people just getting into higher end sneakers (like myself). They're a classic and versatile looking shoe, unlike some other high end releases. ::cough MMM vaginas cough::
