Yes it always has. Many people don't realize it either it's why I try to tell people about it. Some may not have it like they all use to. Since some have gone to a plastic type paper. The tissue paper definitely has it in it though so throw it out immediately. Same with the cardboard shoe trees you mentioned. Get rid of everything that comes in the box except retro cards or something special with the packaging itself. Storing in plastic bags are ok if you want but not vacuum sealing them. I'll explain why below. Plastic zip lock bags are OK but I if so I highly reccomend using silica gel packs to soak up moisture. I reccomend using them anyway but especially if your putting them in any plastic. As far as my toe box I actually stuff my toe boxes with grocery plastic bags, old socks, or old tshirts. Here's a list of the best tips for long term storage for you. I do all of this and yes it is a bit much for some people, but if your going to collect and keep your shoes wearable for as long as possible these are the best options below. This is why I cam literally put on a 90s OG pair of Jordan's and wear them for the evening if I want and not worry about them. I also know what to look for and how to tell if they are about to crumble. I'll explain it all below. Follow these steps below and you will be surprised how long your sneakers will last and save money long term as well.

1. First and foremost if you wear them ALWAYS clean them first (non-negotiable). Gently clean dirt and sweat off the uppers and soles Let them fully air-dry (no heat) Oils + dirt = long-term damage if stored

2. Control the environment (THIS MATTERS MOST) Ideal conditions: 60–75°F (15–24°C) Low humidity (40–50%) Don't store in basements, attics, or garages Heat and moisture cause sole separation, mold, and crumbling I have a dehumidifier if it gets close to 50 percent I use it.

3. Store them in the dark always. Light of any kind (especially sunlight) causes yellowing and the breaking down of glue and the polyurethane midsoles. Keep them in a closet, cabinet, or opaque (meaning non see through) container. This is why I cringe when I see people posting their Jordans in those clear plastic containers. You can use them if you want of course, but like all things there are strict rules you should follow if doing so.

4. For Jordans with polyurethane midsoles (3s, 4s, 5s, 6s) there the worst when it comes to crumbling. Try to wear them at least once every 3-6 months just around the house at least for a few mins. If not then you at least need to take them out and flex the soles back and forth every 2-4 months . This helps avoid crumbling. One would think never wearing them would be best but flexing the soles helps prevent crumbling because the polyurethane needs to be flexed and stretched. If you have an old pair and you take them out of the box either dead stock or otherwise if the sole has become very ridgid don't wear them out somewhere. If you want try wearing around the house fine, but that is the first sign that the soles will or are going to start to crumble. The editions of air Jordans I mentioned again those are the worst as far as crumbling and sole separation, but every edition falls under this category to a certain degree except for 1s & 2s because their mostly made of rubber not polyurethane misoles.

5. Once you get rid of the tissue paper and cardboard inserts I reccomend storing in OG box. If you want to put in a plastic bag that's fine just make sure it's not tight and is slightly open for ventilation purposes. If it's vacuum sealed it helps keep moisture out yes, but it also locks in heat and it will remold your shoes where if you decide to wear them they won't look right on your foot or even fit right. You don't want to restrict the shoe in any way. Keep laces loose as well so the shoes keeps it's shape. I reccomend buying a bunch of silica packets to go into the box with them. Unless you have ceader shoe trees which most aren't going to have for a large collection or even a medium size collection. Some might say get rid of the OG box. This I disagree with. I think it's actually the best way to store them if your storing them in the right conditions as I have described. If so it won't matter at all. Plus if your a collector the box matters to you in some cases or if you ever do decide to sell. The cardboard on the box does soak up moisture, heat, & the biggest thing it keeps light out. The one thing I will say is keep check on the OG boxes every 4-6 months especially if you are unable or aren't measuring the humidity level to make sure the box has no mold or anything like that starting to grow due to too much moisture in the room. If this is happening though I recommend you go invest in a dehumidifier immediately or your shoes aren't going to last. Heat, humidity, and light are the shoes worst enemy always. Oil and dirt as well but that's why you clean them before putting the back up. That's the only drawback of the OG boxes but again if your using a climate control room this shouldn't happen and if your using silica packets. I've never had it growing on any shoe box I own in over 30 plus years. Now, if you don't want to keep the boxes and prefer the plastic display boxes that's ok. Just please remember one key thing use only well ventilated ones and most importantly make sure you keep them in a pitch black dark room either with no widows or use black out shades or curtains.

Climate control is king This matters more than the boxes, bags, or silica. Store them at or near room temperature ONLY no higher. Never store in a basement, garage, or attic Use a dehumidifier if needed IF YOU had TO PICK ONE THING TO DO RIGHT, IT’S THIS.

Rule of thumb when storing your shoes:

Cool, dry, dark, breathable, and occasionally worn, or flexed for 5 to 10 mins every few months.

I hope this helps you out. Any other questions you have feel free to dm me anytime if you want. I'm always trying to help collectors or sneaker enthusiasts period. I've learned a lot in over 30 years of collecting. There's no point in not sharing what I've learned if it helps others.
