Despite all their marketing suggestions to the contrary, no manufacturer has ever invented a shoe that is any help at all in injury prevention. If anything, the injury rates have actually ebbed up since the Seventies - Achilles tendon blowouts have seen a ten per cent increase
In a paper for the British Journal Of Sports Medicine last year, Dr Craig Richards, a researcher at the University of Newcastle in Australia, revealed there are no evidence-based studies that demonstrate running shoes make you less prone to injury. Not one.
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.’
Despite pillowy-sounding names such as ‘MegaBounce’, all that cushioning does nothing to reduce impact. Logically, that should be obvious - the impact on your legs from running can be up to 12 times your weight, so it’s preposterous to believe a half-inch of rubber is going to make a difference.
When it comes to sensing the softest caress or tiniest grain of sand, your toes are as finely wired as your lips and fingertips. It’s these nerve endings that tell your foot how to react to the changing ground beneath, not a strip of rubber.
To help prove this point, Dr Steven Robbins and Dr Edward Waked of McGill University, Montreal, performed a series of lengthy tests on gymnasts. They found that the thicker the landing mat, the harder the gymnasts landed. Instinctively, the gymnasts were searching for stability. When they sensed a soft surface underfoot, they slapped down hard to ensure balance. Runners do the same thing. When you run in cushioned shoes, your feet are pushing through the soles in search of a hard, stable platform.
‘Currently available sports shoes are too soft and thick, and should be redesigned if they are to protect humans performing sports,’ the researchers concluded.
