So I keep getting a lot of similar comments about how I did it so I decided I'd pin this comment as a sort of FAQ. 1. "You only drilled one hole, you should have drilled another as an air vent" Yes, this is true BUT I believe that the fact I didn't drill air vents was a key factor in the success. Drilling air vents would have made it significantly easier to fill the unit with silicone however I think this would have resulted in a worse shoe. Because I didn't drill any, I actually ended up inadvertently plugging whatever tiny puncture was letting the air out, and was able to "pump up" the shoe again. This would not have been possible if I had let all the air out. This is what made the end product so good. Filling it with silicone completely not only would have made it even heavier, but silicone doesn't provide as much "pressure" as you'd think; the trapped air was necessary to take the shoe from "wearable" to "pretty good". My advice is to choose the method you think will work best. I kinda did this pumping up thing by accident, so it may be that drilling air vents and going for maximum silicone fill is more reproducible. 2. "How long does it take to dry" If you mean dry as in when does it stop oozing out, I kept picking away at it and removing the excess until it sealed itself more or less cleanly. This took maybe about 5 days. I don't really remember. If you mean dry as in stiffen up, it might never. Like I said for the previous question, I don't believe the silicone alone will provide enough spring to make it feel like it did before. This could be for a few reasons: Maybe it doesn't cure because inside the air unit there is limited air to react with, or maybe the silicone just isn't stiff enough. 3. "They are so heavy" Yes they are. But this doesn't matter. For me it's only noticeable when I hold them, not when I wear them.

The best way is to lay the silicone tube (sealed) in hot water for 20 minutes. It flows out much easier and fills the cavity loads better. Also, with a really small a screwdriver (ideally a small pick) poke holes all the way round the underside right to the end. Maybe 7 holes each side. This allows air to escape (but not sealer to escape) and again, it flows real fast and smooth and fills properly. This also speeds up drying time which btw is around 4 days. 1 sealer tube fills one shoe exactly and if you only have 1 shoe that’s popped, do both because they feel different when wearing them. They look amazing if done correctly

This reminds me of the pair of Nike air-cushioned shoes I bought more than ten years ago. I only wore it for less than a month before the bottom cracked. When I returned the entire pair to Nike, they said it was caused by external force and refused to refund the money. I have stopped buying anything Nike related products since. I started buying Asics and some less popular brands like Brookes, New Balance, and even some long-established Chinese brands. I still have the shoes in question and use them as a reminder to me or others. I have kept this for a long time and thank you for giving me the opportunity to share my experience.

Just bought my first pair airmaxs and see this video right away so glad it didn't take much to find 😅 I'm going to try 🤞

Thanks for the great video, I tried it on an almost new pair of airmax that had been punctured by a drawing pin. It only worked!

I've been wanting to try this for YEARS. I have had dozens of pairs die prematurely from the 4 other versions of polyurethane midsole death but no popped bubbles. But I take comfort knowing that when i pop a bubble at least it's the problem with an actual solution.

You should’ve made at least 2 holes -avoiding the air compression that made it hard to inject more silicone. And another top is to use crystal silicone, it’s more transparent and looks like water when you use it. Putting the unopened silicone in hot water for 5 minutes would also make it flow a lot easier. 9/10 for effort though

I did one of my 720s a couple of months ago and yeah it was really messy and it kept oozing out so what I did was make a very small plug so it wouldn’t connect with the floor which was perfect and the extra weight didn’t bother me at all but now the other bubble in other trainer has popped what an absolute rip off £160 and I’ve worn them about 12 times but I’m determined to get my money’s worth out of them so I’m gonna do the other one would you drill a couple of holes in them so the air expels so it doesn’t spew out what do you recommend Peter?

There may be improvements or alterations to the process but nonetheless the idea and the implementation presented are great. Thank you!

Hello buddy ,I’m Ross and I’m a fan of 720 818s but I think you have made a really fabulous invention. I can’t get mine as good as yours but your right silicone feels better than the AIR. Thanks 🙏🏼 for sharing and saving my 818s thanks again Ross 👌👌🙏🏼

What did you use to fill the drill hole when the silicon was in the shoe

I just did this yesterday and it has worked thank you so much I was going to bin them

Man, it happened to TWO PAIRS OF Nikes. I found a video a while ago from a Brazilian guy (my home country) and it worked just fine. I came to the conclusion that the silicone itself offers spring enough to support my weight (I’m 150kg). I live in Chicago USA and I sent the first pair to Nike and they didn’t do anything for me. Shame on them. You did a great job, specially because you had to handle things that didn’t go as expected and you did it regardless!

I think you have to make 2 holes one in te front and one in the back, so the presure wil go out from the other hole?

You can mix water with dish liquid and spray it on the sole similar to finding the leak on a flat tire look for air bubbles when you apply pressure and that should help anyone find the precise leak location

mine have just popped, but 3 years out of them can't complain, I'm going to give this a try

is that there a air refill hole under the insole?

my TN‘s popped in like 2 months and now they look like my dog chewed them dead i don’t recommend them they are falling apart like sandstone, i‘ll just get it repaired and try your silicone method thanks for the video mate

“I’m an adult I can make my own choices” - famous last words 😂😂

Really helpful man appreciate that video

All you have to do is drill two relief holes absolutely tiny on the other side of the shoes. I've done this with my vaporMax. Basically there is no way for the air to escape. And adding glow in the dark silicone would be amazing!

Hey Peter thanks for this idea. How do I close the holes?

Can you do it with plastic bags

Looks good mate , good idea thanks

Does it matter what silicone (brand?)

Do the shoes become a lot heavier after you add the silicone and would this work for a vintage crushed bubble 🫧??

Hi, bro I have a question about how I can know if my shoes are original or fake. My shoes is Nike air max 720

They would be solid ?

idk what to do with my pair of jordan 35, the zoom popped and its hard to put silicone in it. somebody know what to do?

I stepped on a firework with mine because it was too close to my kids. Needless to say the melted a bit and I lost pressure in one of them. They were about a month old at the time and 200$. They have been sitting in a box for 4 years now. I might try this. But maybe with an expanding foam. Idk.

I have a bunch of 720s, luckily none of them have deflated yet but if any of them do I'm going to get some black silicone lay it hot water and do this trick!

Well done 👏

Did you have to seal the holes

If u take the insole out there's a little valve like a black dot where u can get a football pump and pump them back up... most nike air max have it if u check. It will save all the messing around

Bisogna riempire tutta la gomma di silicone oppure solo la parte sgonfia?

Did mine seems okay 👍

I just fix my vapour max today I went out and bought the exact thing you have and it works perfect but I’m trying to stop the silicone from coming out like how do I stop that I tried glueing the spot where did the injection at the injection site but I guess within time.

I will do this to my air max 720. But the fact here is that Nike has a bad quality control with this model. I had the air max 2015 and never happens this things. Thanks for the video.

Great job bro, but I have a question. Does the shoe with silicone inside feels heavier compared to the one without? If yes, how much? Does it ditrurb you while walking?

I've popped air max after seriously beating them. I guess I haven't thought about my 720 doing the same. I hate that anyone has to deal with it out of the box. Or how often this is happening. For the most part Nike will refund your money depending on time. then again I do own several so maybe I don't wear them often enough to pop them? Good luck to all you with your air max

Well done. Silicone, logical choice. I like people who are ready to get their hands dirty to repair the un-repairable.

Hello mate I have also done this hack with my 270s and used white silicon. How heavy are your trainers after doing this.

Hello how many tubes for 1 shoe cheers

Can i do this without the punture kit, did you put this puncture things over all holes you made?

How long do you leave them sitting and do you recommend using the same technique for mine? Mine actually have a tear between the rubber from the air bubble and the rubber of the sole

I’m ma give this a try today I tried an air pump but this seems more likely to provide a long term wearability

I really like your video. When you first started filling the hole, I started laughing due to the mess. It seems to really work. I’m going to try this on my airmax 720. I lost my receipt. I will give you an update. Thank you for this video. Sincerely Kenneth

Thank u so much cause it will help me a lot are from Barbados

Definitely giving this a go

Do they feel heavy tho? I need to fix mine , only 1 of the shoe’s broke ffs. Thanks.

Job done and dusted. All fixed 👍

how does this hold up long term , will the silicon not just eventually start oozing out again if it doesn't dry on the inside because of no air

How much i need to wait after filling them? 3 days are good?

Make a hole up front by the red pad for air to escape u are fighting air pressure

How about using a POLYURETHANE EXPANSION FOAM? This may not affect the weight. What do you think?

Looks good enought to try

You need to make two holes so that any trapped air/N2 can exit while you are filling it with silicone.

Hey how it is going after 7 months are there some bad experience behind it after some time ?

Probably it's coming out due to over-pressure. Since the silicon takes up volume and thus compressors the air inside. So it finds the points of low resistance. It would be great if there is clear self seal. Like the stuff you can put into tires

You need three holes , the one you pump the silicone from and two small holes in the end to leet the air out while you fill it , simple physics !!!! You will be able to do it in one go .

Anyone done this with the black pair? If so did the silicone look that bad? If it did, is it worth messing my other trainer up and silicone them both to match? Thanks. Would do this, just worried about the look

Do it bro start repairing people 720’s that would be awesome.

good video bro

So you didn't pump air in there? Only silicone?

Thinking of using expanding foam instead

There must be better silicone though like one that dries perfectly clear not murky white. I want to do this with my 2 pairs but they are clear soles and id want the silicone to dry clear. Can any one recommend any? Also if you make 2 smaller holes on the inside near the front that air can release as you put it in so it won't swap back out

I have 3 pairs my left popped on all 3 pairs. Sucks

thanks

Nome do produto?

Must be two holes - for silicone in and air out. Will try the same myself. There are videos they suggest make holes from upper part ...

My 720s got a hole too

What’s the silicon called btw ??

How do you blocked the holes

How much silicone was used exactly??

E se dovesse rimanere aria dopo che il silicone si ė asciugato

Did mine a week ago and the silicone is still as soft as when I put it in

Because you only had 1 hole the air inside was getting stuck/trapped

Ok I tried this it's ben 12 hours there not drying inside not to mention the holes are still oozing. There heavy like a pair of steel toe work boots. I won't be doing this too my other 2 pairs . Il try to send them back to Nike. My advice don't do it sorry it's a fail

Saludos a todos desde Brasil. No recomiendo este procedimiento. Queda mal hecho y no dura nada. Lo mejor que hay que hacer es cambiar las suelas de tus tenis o zapatos usados. Se puede poner primero unas medias suelas de EVA, pegar y luego lijar. Después pegar unas suelas de latex antiderrapante. Y ya está ....hay muchos kilómetros más a caminar.

Get in lad

You know there a valve under the sole

il faut mettre de la mousse expansive , trous a faire sur les cotés 'c'est nikel ! ! très légé et en 30 secondes c'est sec !

Can you not just seal the puncture that caused the air leak? Existing air can no longer escape thus restoring to it's original state, theoretically. Unless the bubble holds compressed air originally. 🤔 But that would seem unlikely. If a puncture itself can be resealed, there would be no need to add the additional weight and mess of silicone.

Con este método quedan muy pesadas se pierde la sensación del como viene de fábrica .Yo con mi técnica logré reparar a mis clientes y a dado buen resultado y lo pueden ver y aprender como lo hago.

Now my sneakers weigh 621 grams

The shoes become too heavy

Cooles Video das würde 2 Paar 720er von mir retten

Mine exploded just walking

powinieneś zrobić drugą dziurę żeby powietrze miało gdzie uciekać. Wszystko wylatuje bo zrobiłeś w środku ciśnienie.

God bless everyone pray for forgiveness Jesus is coming soon. you do not want to go to hell and burn for eternity forever.go with God read the bible every day at least one paragraph. pray every day for forgiveness baptize you. trust me it's worth going with God you will even get a crown on your head when you go to Heaven. God's heaven is so beautiful we can not even imagine how beautiful it is. remember it is not yet too late to GO with Jesus and God God loves us so much so he sent his only begotten son so that he would die on the cross for us and resurrected on the 3rd day God and jesus loves you 🙏🏼 Amen

Not gonnna talk about they weight 3kg each after filling them up 🤣

The best way is buy a new one

LMAO 🤣👍

Bon chonce

Anyone else have a pair of 720s not worn them for abit and now they are flat 😂😂

Nike silicone max. you gave your shoes a kim k job.

are you eligible for a refund if you got them online at dicks sporting goods ? mine are falling apart the bottoms are flapping when i walk they are talking to me, telling me to buy new shoes 😂

Seriously, throw them to the rubish and purchase a new one. It s the best way...

Well fucked job! You better play your dolls 😂😂😂😂😂😂

1.50 kg😂😂
