Cheaper running shoes win comfortably - being-human - 11 October 2007 - New Scientist

http://www.newscientist.com/article.ns?id=dn12776&feedId=online-news_rss20 --- Upscale athletic shoes often claim added protection against the bodily wear and tear of running, and indeed some studies suggest that pricier materials can more effectively reduce impact force than cheaper ones. Other evidence, though, suggests that runners wearing fancy footwear are 123% more likely to get injured, possibly because they over-estimate the protection and run with greater impact (British Journal of Sports Medicine, vol 91, page 299).

haha science to the rescue
