Why don't they put helium in shoes to make them lighter?

Because there are easier/better ways to lighten a shoe by .06oz

Because a perfect vacuum, which only exists in your head, is lighter and weighs nothing.

You're on the right track with the shoe idea but everyone knows that running with a helium-filled Camelbak is much more effective.

true, balloons help lessen your weight, but the increased drag cancels that out, so camelbak is the way to go

Just compress the helium and put a lot of it in! That'd make the shoe SUPER light!

Just run with a helium tank on your back!

Maybe because the sole would be too soft, unless you pressurise the gas, making it heavier and negating the benefit. Nike air shoes have pressurised air

. Also, cancelling a significant proportion of, say, 100g (a pretty lightweight shoe) would probably require such a volume of helium it would be impractical.

Creating a vacuum in the sole would probably be difficult (need for rigid and probably heavy material). And what's to be gained? This would probably not provide shock absorption. If it doesn't, then it's probably better not to put anything in the first place.

Congratulations, you just won the most boring post of the month.

I answered the question.

For your information, you are not funny either.

Isn't this the concept of Nike Air?

No, it's the concept of Converse Helium.

For the record, I thought grox's post was fascinatingly informative.

A+ CORRECT ANSWER!

Not only is grox' post terribly boring and self evident (unless you're an airhead of course), it's also plain wrong in that it should require a huge volume of helium. Just look at Converse Helium.

I just inhale a bunch of helium before I run.

Or You could go for the lightest possibles option... no shoes.

Hydrogen is lighter.

The better choice is anti-matter, you will realy take off
