The first article was shown to me by Mr. Jason P., triathlete and future barefoot runner (maybe.) It was published on Lifehacker.com, which is actually a really cool site. They post about random tips and unorthodox ideas, and have an affiliation with Gizmodo, a unique gewgaw site. The story just repeats things already talked about here, like Dan Lieberman's barefoot running study, but it's worth checking out the rest of the website to get a different viewpoint from which to look at the world.
The second article is from Yahoo! News, and is titled "Running Shoes Changed How Human Run." Again, there is nothing new in this article - it just summarizes Dan Lieberman's research. The best part of the article comes right at the beginning though:
When you strap on a typical running shoe, you may be fighting evolution. Modern-day running shoes have changed the way people run, altering our gait from that of barefoot running - the manner by which people ran for thousands of years before the arrival of the cushioned shoes found on store shelves today - a new study suggests. I'm curious to see how long barefoot running remains in the news after the fallout from the study settles down, but I do hope the news sparks some interest in the average runner and helps them make running more fun, more safe, and a better workout.
