Barefoot running has seen a huge rise in popularity in recent years. But researchers conclude you're still better off sticking with your running shoes.
"In general company, avoid discussion of politics, religion, or sex," goes the ancient maxim of etiquette. If you want to keep things civil among the North Brooklyn Runners, add one more topic to that taboo list: barefoot running.
Barefoot running, as well as running with minimalist shoes like Vibrams, gained new popularity a few years ago after Stanford University coaches claimed their runners suffered fewer injuries when running without shoes. Proponents of running barefoot claim that advances in running shoe technology, with more supportive soles and shoe structure, actually cause more injuries than they prevent.
On the North Brooklyn Runners online message board, pro- and anti-running shoe posts build up heated debates lasting weeks at a time. Converts to barefoot running write as if they're trying to convince everyone else that world is round, while proponents of traditional running shoes post as if they're defending a religious sacrament.
Scientists at the University of Colorado have completed the first in depth study on the physiological benefits of running shoes, the New York Times reports.
Previous studies had suggested that physiologically, the weight of running shoes makes running more difficult. Every 3.5 ounces of weight added to a person's feet appeared to increase their energy cost by about 1 percent.
For this study, the researchers recruited 12 experienced barefoot male runners. They had them wear lightweight shoes, just over five ounces in combined weight. The runners ran multiple times on treadmills, with and without shoes.
To test if barefoot running was physiologically more effective than running with shoes, while controlling for shoe weight, they taped five ounce strips of lead to the top of the runners' bare feet.
Running barefoot with the five ounce strips required four percent more energy than running in the five ounce running shoes. The researchers attribute this difference to the cushioning effect of the shoes.
More importantly, the researchers also found that for 8 of the 12 runners, unweighted barefoot running still required more energy than running in the lightweight shoes.
This study only compared the metabolic efficiency of wearing shoes versus running barefoot, it didn't compare incidence of injury between the two options.
Still, the researchers conclude that most people benefit from wearing running shoes, though they advise runners to choose lighter models.

I believe to run with sports shoes. Sport shoes are made of comfort sole which makes us feel calm while running. My favourite brand is Sparks for sports shoes. sparx shoes online
I really love all data that you just provide in your articles. http://www.progait.co.uk/about-us
"More importantly, the researchers also found that for 8 of the 12 runners, unweighted barefoot running still required more energy than running in the lightweight shoes." So this implies that 4 out of 12 runners ran more energy-efficiently while barefoot. If so then the study should focus more on the various differences between the 8 runners who do better in shoes and the 4 that do better barefoot. Those differences are what would be the factors that dictate success or failure for everyone else I would imagine. figure them out, then finds ways to test them in any given indivudual, and if that individual matche to one category or another than you can tell them they'd do better barefoot or not. I'm sure it's not that simple but in concept, perhaps it is? Not that I think only 12 people are enough to gauge the human race but anyway, what are the reasons those 4 barefooters were able to do better without shoes is what I'd like to know.
Personally, i would not want to run on a treadmill or anyhard surface without shoes. However, I think it is like a foot massage to run barefoot in grass or on sand or a softer surface.
This is the study that convinced me to switch to Vibram FiveFingers: http://www.eurekalert.org/pub_releases/2010-01/ehs-rsm010410.php
anyways ? I don't think they are running just for the fun of it. 4% additional energy consumption is NOT going to increase their grocery bill ! The whole idea of running, IMHO, is to expend energy and get your metabolism going to stay trim and healthy.
Thanks stancube. I hadn't seen that article before, though I've certainly heard a lot from the "heel striking" camp. I also appreciate that this study included women runners, a lot of studies (including the one I reported on) look at only males, even as researchers are finding that results in sports research can vary widely between genders.
I think the idea is that some people are wondering whether expensive supportive running shoes might actually cause more harm than good. But I agree with you, I have no problem with spending a little more energy every time I run, I'd actually welcome it!
