Depends on how broken in your pair is. The longer you have worn and owned them the better. But the ventilation suffers greatly. I personally wouldn’t wear them all day but it’s a personal preference.
Find the tag on the inside collar. It should have a two digit month and a two digit year, followed by a longer sequenced set of numbers usually with the letter “A” in it. Google that number and see what jerseys come up to compare. That’s a good way to check if it’s legit.
I wish i had both to compare but I have Jordans from the same era that have not made it. IVs where the netting broke, cracked nubuck, etc. In hindsight I should have made more AF1 IDs.
