Absence of evidence isn't evidence of absence.

Those links relate to Vibram making unverified or unproven claims, not claims known to be false.

If you make claims, and you can't prove them, you're lying.

And yet, the claims may still be true.

Moral judgement of making unsubstantiable claims is different than proving the claims false.

That looks a lot like a claim to me. Can you prove it?

Is that a subtle version of "This sentence is false"?

While this is purely anecdotal, I run in Vibram FiveFingers shoes and find that I have fewer blisters and less pain afterwards than with conventional running thick-soled shoes. YMMV.

I also use Vibrams for running, hiking, and normal daily activities. Some in the biomechanics field swear by them. I just like how they feel and look. It seems logical to keep a shoe as close to barefoot as possible since the foot evolved without any of our modern sole/shoe tech.

How far do you run?

I run ~20 miles a week (not that far) in normal shoes and never get blisters.

I don't run that far but I'm very prone to blisters. Weak skin I guess.

Okay, sure, so they aren't effective at "strengthening muscles or reducing injury", as Vibram claimed.

Those aren't the benefits at issue here, though.
