There have been many advances in running shoes over the years.
But thanks to a group at the University of Central Lancashire in Preston, a giant leap may just be around the corner.
They have teamed up with a firm that makes mattresses to produce a trainer with springs in the soles.
Adam McClean reports.
Health researchers in Lancashire have designed a new type of trainer, containing miniaturised mattress springs. They claim the springs can reduce injury.
Prof Jim Richards, from the University of Central Lancashire, explains how the design creates a "shock absorber" that is similar to one in a car.
Health researchers in Lancashire have designed a new "super" trainer, containing miniaturised bed springs.
A team at the University of Central Lancashire worked with a mattress manufacturer to shrink the mattress supports into the soles, to try to reduce running-related injuries.
"If you had a car suspension with just a damper and no spring in it then you'd have a very bumpy ride. Therefore having a shoe that incorporates both provides a much improved shock-absorbing system compared with existing technology," says UCLAN's Professor Jim Richards.
"We will also be able to tweak the arrangement for each individual runner", he says, "which is particularly important because everyone has a different running style and physiology that impacts on their risk of different types of injury."
