Running without using running shoes had been a gimmick which commenced about 10 years ago and continued a few years. This grew to become very popular however faded away just as fast as it emerged. It had been based on the theory that running shoes are usually not good for you and that running with out them is more natural and better for runners. There was plenty of books written and published about this, lots of websites encouraging the claims and lots of social media activity affirming the claimed advantages. Nonetheless, what actually transpired is that the positive aspects that have been presumed for this did not worked out for most runners which took it up and there was a quite high injury incidence in those who tried it out. Runners soon went back to what they were acquainted with and all the guru’s whom started off promoting it aren't heard from.
There was no studies that barefoot running was actually any better. It was mostly made up claims depending on anecdotes. Once the research got carried out it revealed that many of the claims which got made up for it were exactly that, made up. The benefits over using running shoes are not there. Barefoot running is simply different to running in shoes. Since the barefoot fad died off, there was clearly a conversion to considerably more highly padded running shoes. This was the opposite to the craze of barefoot and it too got termed as a fad. However, at this time there isn't any indication of that trend to the high padded running shoes dropping off, so it is in all probability safe to say that it is not really a fad but a long-term trend. Running barefoot or with traditional running shoes or using maximal cushioned running shoes are simply different. One is not better than the other and individual runners should have their personal choices as to what they prefer to run in and that is okay.
