What science demonstrates that running on springs would be beneficial? Basically the runner and his or her shoes is a closed energy loop. Without an external source of energy, shoes cannot create extra energy for the runner.

So if the spring returns more energy, it also requires the runner to produce more energy.


Not really. Animals that run faster than us use springs so we're essentially trying to alter our conformation to duplicate their advantage. I[/quote]

I am no expert in biomechanics or physics, although I do have an engineering degree, so I would love to understand more about how a spring would work to "create" energy. Not trolling, I really am interested.
