If you're more than 71kg, you shouldn't wear lightweight running shoes

Although lightweight running shoes have grown in popularity in recent years, including those trying to mimic a "barefoot" running experience, the new study suggests that the amount of padding you choose should depend on how much you weigh.

Carried out by the University of South Australia's Sansom Institute for Health Research, the researchers looked at the 61 trained runners across a 26-week period.
