Damn, just saw that. I'm a little surprised these are going so quick. Though maybe once the initial rush dies down sizes will come back in stock on the app and online.I guess i was too late for snkrs. I dont even have a button on the 12s to buy them.
That being said, if you got charged on Finishline you might be good. I've had Eastbay and Footaction orders do that where my card was charged hours before I got any sort of confirmation. They all went through fine eventually.
