That is according to David Castle, editor of Running Fitness magazine, who has suggested that incorrect footwear can lead to serious injury.
He said: "With so many products to choose from, it can be confusing: our advice would be to visit a specialist running retailer who will look at your running style and advise you accordingly."
Mr Castle implied that people often spend so much of their attention on correct running shoes, they neglect to look at the type of socks they are wearing.
He said that so-called performance socks can help to stop blisters forming and may provide support for key areas of the foot.
A 2008 study by researchers at the Stanford University Medical Centre team revealed that people who run regularly are less likely to die of conditions such as cancer, compared to those who do not run.
