to clarify,
4.2 ounces for $29.95
3.2 ounces for $41ish after shipping
Yes definitely 1 less ounce of weight is roughly 1% less oxygen required. But that should not be the only factor which spike has a aggressive spike (for example) could arguably make a bigger difference. Also which particular spikes are you talking about?
Dude, posting about $11 ? Don't take this the wrong way but.... get a decent job.

How is 1 ounce worth 1% less oxygen? If I lose 100 ounces, I'll not need any oxygen at all.
you gonna chop off your feet?
Those saucony endorphin spikes fall apart in about 1-2 seasons, if thats what you're looking at. If you do workouts in your spikes, they might not even last until the end of xc.

Nope. I've done close to 200 miles in my endorphin md3s over three seasons, mostly on track but with the odd xc race as well, and apart from a worn spike plate they are still perfectly functional, which is ludicrious for such a light racing spike. The upper is good as new. I've tried a lot of spikes and nothing else even comes close.

Wear the spikes that are the most comfortable and work on getting stronger. Your body's weight will even out with added strength and the ounce of weight in your spikes will not matter.

when you said you'd remove 100 ounce for no oxygen need, I think you misunderstood that the 1 ounce to 1% O2 ratio referred to weight on your feet.
so to remove 95 ounces after removing a 5 ounce shoe, you need to chop your feet up.
Do the shoes fit equally well? Cushioning? Spike plate length, flexibility?
Which looks better?
At those prices, I'd be tempted just to buy both.

I didn't misunderstand anything. No one said anything about the relationship being limited to weight on the foot. My question was based only on the information provided. My question still stand though even limited to the feet: If i chop off my feet, then i won't need any oxygen at all to run? I would like to see proof of this idea. Where did this 1% per ounce idea come from?

Do you happen to work for the government? jk
Okay I was wrong 3.5 ounces reduces ECONOMY by 1% but still its a fairly large difference over long races.
But yes it is in terms of weight on your feet because you move them so much. Like how the best marathoners have very thin calves.
I don't feel like buying the article but it is quoted here
http://fellrnr.com/wiki/The_Science_of_Running_Economy#cite_ref-Franz-2012_9-1as saying that Each 100g/3.5oz added to the weight of each shoe reduces running economy by about 1%

The best marathoners have very thin calves because they are tiny little East Africans. Calves aren't why they are better.

So 1 ounce is irrelevant unless the OP is doing ultramarathons. OP, dont spend $10 for an ounce. Shoe weight is not why you aren't as fast as you want to be.
