Has anyone done any research on the benefits of Nike Air?

I've always been curious if the gas in Nike "Air" has actually made for a better shoe. Has anyone studied this in a non biased way. (Nike scientists making "factology reports" don't really count.) Do runners get less shin splints because of the padding? Or is it just a gimmick?

I work for a competitor. All the technology works, but an important factor is the fit of the shoe and how a person runs. Yes runners get fewer shin splints from the air or any other shock-impact or shock-dispersion technology, like air, gel, grid, etc. They need to get a shoe that fits well, is designed for their weight and gait type (overpronation, underpronation, normal, etc.), and change it out every 400-500 miles.
If you're a runner, go to a run-specialty store and get great advice for the right shoe for you.
