I'd just call 3rd street promenade Monday morning and keep calling. They are getting every size up to 13. Just spoke to a really helpful guy at the Culver City Adidas store, and made it sound like they still have a few pairs left in the White UBs. Give them a call if anyone is in the LA Area as they are gonna be gone by the time they close at 9pm PST.
Phone Number for the Culver City location is 310-313-5726, press 4 once you hear the automated option menu (it gets you directly to that store instead of listening to the options on how to apply on online for a career where the automated voice proceeds to spell out adidas.com/careers letter by letter.... lol.
hope some of you can go cop, my roommate is a size 12 and has had a pair of white ubs for about 2 months, get real jelly every-time he rocks them.
guess my all white roshes will have to do for now:
