At a recent conference on the science of sport in London, hundreds of participants in droves following the two-hour discussion about the merits or lack of running without shoes.
The debate centered on whether to walk using a shoe with a padded heel and structures that support change in motion is more likely to cause injury.
Advocates of barefoot walking with saying that the more natural way of allowing runners to land the foot on the soft parts in front, not with the heel planted on the ground like most shod runners.
In a study published in the scientific journal Nature, Daniel Lieberman, professor of evolutionary biology at Harvard University, trying to find out how our ancestors to run and hunt for millions of years in bare feet.
Lieberman and his colleagues from the UK and Kenya studying runners who always walked barefoot, runners who always wore shoes, and runners who had left his shoes.
In a series of analysis, researchers found that even on hard surfaces, barefoot runners are planted on the ground to produce a collision with the front surface of the ground which is smaller than runners wearing shoes.
Barefoot runners also have a step that is more flexible and more efficient use of the calf and leg muscles.
The same is noted professor of biology, Daniel Howell, who teaches human anatomy and physiology at Liberty University in the United States. Howell was nicknamed 'Professor Naked Feet' by his disciples after his life began to undergo 95 percent without the use of shoes.
He was admitted as an extremist and for nearly six years are barefoot. He walked thousands of miles in all weather and terrain barefoot.
"Naked foot is a natural condition. The process went very complicated from the perspective of biomechanics and if you add a device to the foot, it changed the process. The device is changing the way up, how to walk, and how to run. The changes were not reasonable and generally negative," said Howell.
While it is true, almost all modern athletes use running shoes in international sport competitions. However, some barefoot runners have tried to pioneer change.
In 1960, runner Abebe Bikila of Ethiopia, one of the greatest runners in the world of Olympic marathon, won the first gold medal without shoes with a time of 26.2 miles in 2 hours, 15 minutes and 17 seconds. And in 1984, named the South African runner Zola Budd barefoot world record by running 5,000 meters in 15 minutes and 1.83 seconds.
