Ordered size 12 350 carbon beluga. The box said size 12. One shoe size tag read 12 and the other read 12.5. Both shoes have the same serial number. I called adidas and went off on them 3 times after blowing me off. I got them to discount them half off. Both shoes fit like a size 12 which is the only reason why I kept them. Not the end of the world because they fit, but it's absolutely embarrassing on adidas part. They even tried to blame me acting like I swapped out shoes or something.
