Unfortunately it's probably going to end up being a Union exclusive so you'd have to hit up customer service in case they have an extras or see if they can possibly oop you one from any in-store inventory
Usually when they show the stock list for SNKRS and Adidas/Yeezy Supply, 8-10.5 have the most stock since it's the most common men's sizes (thus more competition for those sizes). Once you hit size 11-12 you see the stock numbers start to go down as the sizes increase.
