Running with shoes was a fad which started around 10 years ago and continued a few years. It started to be really popular but faded away equally as fast as it came up. It was dependant upon the principle that running shoes are not useful to you and that running without them is a lot more natural and more effective for runners. There were a great deal of books written and published about this, a great deal of websites encouraging the claims and plenty of social media activity professing the claimed benefits. However, what happened is the fact that the benefits which were believed for it never materialized for the vast majority of runners whom took barefoot running up and there turned out to be a quite high injury rate in runners who tried it. Runners quickly returned to what they were familiar with and all of the guru’s whom started out marketing barefoot running aren't heard from.
There was never any data that barefoot running was actually any better. It had been largely made up claims depending on anecdotes. As soon as the research got done it revealed that the many promises which got made up for it were exactly that, made up. The benefits over using running shoes are not there. Barefoot running is just different to using running shoes. Since the barefoot novelty died off, there was clearly a move to a lot more highly cushioned shoes. This was the opposite to the gimmick of barefoot and it too got termed as a fad. However, at this time you won't notice any indication of that trend to the high padded running shoes dropping off, therefore it is most likely safe to say that it is not really a fad but a lasting trend. Running barefoot or with traditional running shoes or using maximum cushioned running shoes are merely different. One is not better than the other and individual athletes will likely have their personal inclinations in regards to what they prefer to run in and that is okay.
