Back in January of this year, I put up a post about barefoot running.
Now a group of researchers in Harvard University have carried out a series of tests to compare running with shoes and comparing it to barefoot running.
Most people who run in shoes strike the ground with their heel first. They found that this resulted in a sudden shock as the foot landed.
When people are running barefoot, they tend to land on the forefoot, the foot rolls forward and there is less impact.
Needless to say, if you are interested in trying some barefoot running, it probably makes sense to try it on a soft surface like grass and to run short distances like 1 to 2 miles to see how it feels.
There is a link to a video on the Guardian website.
