The 2010 black Infrared 6 is a personal grail (don't care for the 3M and pinkish infrared color on the 2014 version) and I might be able to get the pack at a decent price off Stockx - are they likely to fall apart after a few wears?
Don't know if anyone's bother to make good reps for these but these are some possible red flags based on the unboxings I've seen: the tag is different (the tag on theirs are a squarer shape and have adidas branding - don't know if it varies depending on whether you got them from an Adidas store...
