Adidas needs to get it together. They dropped a bunch of fire this morning and their website couldn't handle it. Just leaves the people that really want the kicks disappointed.
This happened to me also. The core black mesh NMD's run small for some reason. I went TTS and my toes were smashed inside. Went a half size up and they were still a little too tight but I got used to them.
I'm a 9.5 in UB 2.0 and a 10.0 in Mesh NMD's. I read somewhere that the core back mesh NMD's run small for some reason so this might be the case. I think it might also be because the toe area doesn't stretch as much on a pair of mesh NMDs vs UB's. Just my 2 cents.
