Something seems fishy with those.
The dots on the boost don't seem to be correct to me, in the close up of the boost on the lateral side it looks like there are areas with only one dot when there should be a column of three dots in a row. Might just be the photos though.
The lines/grooves in the boost also look slightly strange but it could just be the pics.
Bigger pics that we can magnify might be helpful.
At this point in the game, personally, I wouldn't consider buying OG NMDs on the resale market. The fakes are getting too good.
