Running barefoot has no physiological benefit in efficiency, shows study.

In fact, runners used 4 percent more energy per step when running barefoot, the Discovery News reported.

"Running barefoot offers no metabolic advantage over running in lightweight, cushioned shoes," the researchers concluded in the study.

Earlier studies have suggested that running barefoot is easier as there is no added weight.

But that thinking does not take into consideration every variable, including the cushioning that shoes provide.

If people are not wearing shoes, the researchers believe, their legs absorb more of the impact of running, causing them to work harder.

"What we found was that there seem to be adaptations that occur during the running stride that can make wearing shoes metabolically less costly," Jason R. Franz, who led the study, told The New York Times.

The "barefoot" runners in reality wore thin socks to maintain hygiene and safety, and the shod runners wore Nike Mayfly lightweight shoes.

"There is some evidence that shoe design characteristics other than mass may influence metabolic cost," the authors wrote.

"Thus, we selected this running shoe in particular because it has some cushioning but no other features such as medial posting/arch support or various other motion control elements," they added.

The study has been published in Medicine 'n' Science in Sports 'n' Exercise.

Bare foot running is already widely accepted as less efficient. it is more effort on your muscles to run a mile bare foot than in shoes. However that is not the purpose of running bare foot. The propose is to take the impact off your heels. Heel impact shod running is the cause of knee and back problems in runners. so yes you can run faster in shoes but your running career will be much shorter.
