Here’s a nice summary of the research on barefoot vs. shod running. Here’s the introduction
Well-known international athletes have successfully competed barefoot, most notably Zola Budd-Pieterse from South Africa and the late Abebe Bikila from Ethiopia. Running in bare feet in long distance events is evidently not a barrier to performance at the highest levels. Indeed, in this review I will show that wearing running shoes probably reduces performance and increases the risk of injury.
I became interested in research on barefoot running when I noticed that a reasonably high proportion of runners compete in bare feet during cross-country races in Queensland, Australia. I have based the review on articles I found containing the words barefoot and running in Medline, SportDiscus, and in Web publications. I found several original research reports on the occurrence and mechanisms of acute and chronic injuries in unshod and shod populations, and a few reports on the energy cost of running with and without shoes (including an unpublished thesis). Two authors provided recommendations for adapting to barefoot running. I also found informal websites devoted to barefoot running and barefoot living. There are apparently no published controlled trials of the effects of running in bare feet on simulated or real competitive performance, nor any surveys on the reasons why people do not compete barefoot.
