 Bro you ever have any crumble? Yeah I have. Prime example 1999 Air Jordan 4 Black Cement also known to the new era of collectors as the bread Jordan 4s. As you can see right here a lot of cracking and separation crumbling already starting to happen. Now I didn't let these things crumble all the way because I like the vintage look and I wanted to store them for you know display purposes and nostalgia but these things could easily crumble at any single moment you can easily tell that it's separating and cracking all throughout their foggy air units all those different things but either way all of these things these things are some beauties and when it comes to Jordan 4s we know that this can happen to these shoes because what they're old and based off of the materials that the shoe is made of that's what causes it to crumble unlike Air Jordan 1s or Air Force 1s those definitely last for a lot longer and have a longer life shelf when it comes to the shoe being on the shelf or actually being worn also we got to talk about Jordan 11s real quick. These are my concords from that same era as you can see I put my time in but they're starting to separate and the carbon fiber can crack on these as well.
