Made this for those who are confused about the differences in the Neutral Grey Jordan 1 Lows over the years.
Each one uses a different mold than the other; Jordan brand seems to switch this up every so often.
Wings logos on the heel tabs are embossed differently at times as well.
Biggest difference and the best detail (in my opinion at least), is the size of the swoosh. 1985 had semi thick swooshes that were also more elongated than the ones you see these days.
2015 had a nice thick cut swoosh, which a lot of us enjoy more.
2021 is the new OG cut swoosh, being a lot smaller and not as thick as the previous iterations. This is the size you typically find on every AJ1 low over the past few years, minus the Travis Scott lows that feature a thick cut medial swoosh.
The 85 retro does better to nail the original shape and size that we originally had in 1985 when they first released.
Hope this helps those who are a bit confused on the topic.
