"Runners wearing top-of-the-line trainers are 123 per cent more likely to get injured than runners in cheap ones. This was discovered as far back as 1989, according to a study led by Dr Bernard Marti, the leading preventative-medicine specialist at Switzerland´s University of Bern.
Dr Marti´s research team analysed 4,358 runners in the Bern Grand Prix, a 9.6-mile road race. All the runners filled out an extensive questionnaire that detailed their training habits and footwear for the previous year; as it turned out, 45 per cent had been hurt during that time. But what surprised Dr Marti was the fact that the most common variable among the casualties wasn´t training surface, running speed, weekly mileage or ´competitive training motivation´.
It wasn´t even body weight or a history of previous injury. It was the price of the shoe. Runners in shoes that cost more than $95 were more than twice as likely to get hurt as runners in shoes that cost less than $40.
Follow-up studies found similar results, like the 1991 report in Medicine & Science In Sports & Exercise that found that ´wearers of expensive running shoes that are promoted as having additional features that protect (eg, more cushioning, ´pronation correction´) are injured significantly more frequently than runners wearing inexpensive shoes.´ "
