"Debunking the Myth of Specialized Running Shoes"

Great title, that's exactly what's going on.

"“I was completely convinced that impact is something bad, and pronation is something bad, and I wanted to show that,” recalls Benno Nigg, a biomechanics researcher and co-director of the University of Calgary’s Human Performance Lab, who helped shape the original theory of pronation."

At least he's honest, and he's working to undo some of the harm he did by not following the scientific method.

However, it doesn't seem to have harmed his career at all...  Find a radical hypothesis, and then find some evidence that appears to back it up, but don't actually test it.  Young scientists take note: this is how you get ahead in Institutional Science.
