I hope it works out for you. They do have a list showing you got a pair reserved so it really is up to the store. If they don’t, they should be selling the leftover pairs anyway so I would press them since you know they have your size.
Glad I was able to get these for me and the little one on SNKRS after footlocker reversed my payment. Hopefully everyone that wants these are able to secure a pair!
Not sure if all of these are still open or if they have the size you're looking for but these places have raffles with US delivery:
DTLR
BSTN
Footshop EU
Shinzo
SOTO
I don't remember who sponsored the competition but I was cleaning up some old files from school and came across my submission. It was my first time designing a shoe and I was hoping something like that might be an annual thing. If enough people are interested, maybe we can organize something...
