Has anyone...

[bostonthreeparty]

I was wearing my hypermaxes and i hit something and it popped the air max. so i was wondering has anyone Popped or used a pair of AM shoes with a hole in theair max unit? is there a drop in performance or comfort? thanks in advance for anyhelp

What exactly did you "hit" that was able to puncture an air bag surrounded by a solid rubber outsole?

I wouldn't think it would be good for either comfort or performance, I would have to see it, but if it's completely popped both comfort and performancewould suffer.

its actually not that much different...hydrogen is whats put in the old AM's...the worth of them will dramatically drop though as the bubble turnswhite...good luck with those...Xx...

i was walking and some rock puntcured the visible air bag

go to a NT or a outlet and get a voucher.. or not if the shoes are in one month of it being purchase from a FTL, Champs or FA they can exchanged for the sameshoe

^^^^nike wont give a voucher for a popped air unit. they only give them for defects in quality and will consider that user neglect.

well it also depends on the manager.. cuz my AM09 pop and i got a new pair without a hassle. and i used to work at an outlet and managers used to take kidsAMs which kids would destroy them . and the managers would most of the time get them a voucher.

its worth a try cause im sure you spent good money on the shoes.

...dang u had to hit the unit pinpoint...

 

[bradnon]

it prolly doesnt hurt the comfort of the shoes..but im not sure..i would say the only way to find out is to keep wearing em

Ummm... no. If Airsoles were full of (highly flammable!) hydrogen, a popped Airsole would probably result in a violent explosion and atrip to the emergency room for a leg amputation.

You're thinking of nitrogen... which rhymes, but is otherwise completely different (and safe).

As far as performance goes, my best analogy is that you've now got a run-flat tire with a big hole in it. It'll still get you around, but if you tryto make it perform aggressively, it's probably just going to let you down...

[h2]What is Nike AIR?[/h2]
The Nike AIR system was developed by Marion Frank Rudy, an independent inventor in California, and licensed to Nike. As Nikedescribes it, it is a "pressurized gas encapsulated in polyurethane." However, both the gas and the capsule have interesting properties.
[h3]Nike's gas:[/h3]
If the gas leaks out of the capsule, it goes flat. Therefore, the Nike AIR design uses a dense gas, so the gas stays inside thecapsule. In US Patent 4219945, Mr. Rudy mentions a large number of possible gases, which he describes as "supergases." Generally, the "supergases" are halogenatedhydrocarbons, with the exception of sulfur hexafluoride. The patent mentions ethane hexafluoride and sulfur hexafluoride. as being the best two choices. Since"denseness" is proportional to molecular weight, calculations with a periodic table would suggest that the gas is sulfur hexafluoride.

Some recent Nike shoes list USPatent 5042176, which describes an improved capsule material that can be inflated with nitrogen. Nitrogen has price andenvironmental advantages over the traditional Nike AIR "supergases" listed in US Patent 4219945.
[h3]Nike's capsule:[/h3]
US Patent 4219945 mentions a large number of different plastic and rubber materials that will work. However, the patentrecommends a polyurethane film. Nike, while not describing the gas in their SEC filing, does indeed state that the plastic is polyurethane.

Also, US Patent 4936029and US Patent 5042176 describe the use of crystalline materials in the Nike AIR capsule that enhance the capsule stability overtime. US Patent 6013340 describes a polyester polyol-urethane composite suitable for a Nike AIR capsule, and some Nike shoes list this patent.

[h2]Would you believe Nike AIR can inflate itself?[/h2]
It does, because of characteristics of the film and the inert gas!

The polyurethane film is somewhat porous to oxygen and nitrogen, while being insufficiently porous to allow the dense gas toescape. Any gas will expand into an area where it is not present, if allowed to. Since the dense gas is neither oxygen or nitrogen, oxygen and nitrogen in theair slowly migrates through the polyurethane film into the Nike AIR chamber. This can result in significant pressure increases over time. as the migrationceases when the gas partial pressures are the same on both sides. Marion Frank Rudy also received US Patent 4340626 for that ingenioustrick.

US Patent 5042716 also performs the same trick, using nitrogen inside the AIR capsule. However, in this case, only thenon-nitrogen gases in the air diffuse into the AIR capsule.
