Running without using running shoes had been a trend that started about 10 years ago and endured a couple of years. This grew to be very popular however faded away equally as fast as it emerged. It was based on the principle that running shoes are usually not good for you and that running with out them is more natural and more effective for you. There have been plenty of books written and published on this, plenty of websites encouraging the claims and lots of social media activity stating the believed benefits. However, what actually transpired is the fact that the benefits that were believed for this failed to materialized for almost all runners which took it up and there turned out to be a quite high overuse injury incidence in runners who tried it out. Runners soon went back to what they were experienced with and every one of the guru’s which started out endorsing it aren't heard from.
There was no studies that barefoot running was actually any better. It was generally made up promises based on anecdotes. As soon as the research got done it revealed that all the promises which got made up for this were just that, made up. The benefits over using running shoes are just not there. Barefoot running is simply different to running in shoes. Ever since the barefoot fad died off, there was a move to far more very padded running shoes. It was the opposite to the craze of barefoot and it too got termed as a fad. However, at present there aren't any indicators of that trend to the higher padded running shoes falling off, so it is probably safe to say that its not really a fad but a long-term trend. Running barefoot or with conventional running shoes or with maximum cushioned running shoes are just different. One is not better than another and individual runners should have their personal inclinations in regards to what they prefer to run in which is alright.
