Mine were replaced as well. Had a pair of NB1s where they switched the L/R toe cap pieces. Took me awhile to figure out what was off. They replaced them without any issues.
Heads up for anyone still looking for the CNY 4.0. I was at the Santa Monica Adidas store on Friday and they stock on them. I know they had 8, 9, and 9.5 for sure.
Weird, my J Crew in SF did not have the special box. I only got the standard one. Maybe they only got a certain number? I didn't get there until later in the afternoon. They still have plenty of all 4 though.
I topped it off with some Jason Markk Shoe cleaner. Rather get some free stuff than pay for the shipping. Came out to $99.45 with free shipping.
Nvm: Missed snowman77's post above which says the same thing
