When movie star Scarlett Johansson was photographed naming in Los Angeles recently, she attracted a lot of attention; for the 27-year-old actress was wearing Vibram FiveFingers, so called because they look more like gloves than shoes, with a space for each toe.

Strange though they may look, these so-called barefoot shoes, which reproduce the effect of barefoot running but with less pain, are just one brand in a range of minimalist footwear. These super-thin sports shoes are causing a stir in the world of running and fitness. Why? Because some experts believe they could make you a better, more efficient runner and that traditional trainers could be doing you more harm than good.

"Wearing a shoe that has lots of cushioning and support affects the way your body naturally moves and studies suggest that this carries a higher risk of injury," explains Matt Wallden, an athlete performance expert. "But with barefoot shoes, the foot can actually feel the firmness and shape of the ground, which allows your body to respond effectively.’"

But before you rush out to invest in minimalist footwear, be careful. These kinds of shoes are not meant for everyone, or at least not straight away.

"Ordinary sports shoes with support are good for beginners whose bodies are not used to the impact of running," explains Patrick Davoren, former Olympic athlete. "It you are not in great condition, then running in minimalist footwear may cause injuries and will turn a lot of people off exercise and running.

If you are currently injured, and figures show that in any given year 65% of all runners are, it can be tempting to try anything that promises to get you back on the road, trail, or beach. But barefoot running is not a method of treating injury nor is it a magical way of suddenly turning you into a great athlete.

Even if you’re used to running, when you start using minimalist shoes you should build up your distance gradually. Start_off’by doing just 10% of what you’d normally run and increase the distance by no more than 10% every week. And a word of warning - you may never have soft feet again
