Your choice of running shoe is a very personal decision. f201You’ve got to balance how well they pro tect your feet and legs with how they fit, how heavy they are and, yes, even how they look. I bet you have a personal favorite that you buy again and again.
    But if it is the quality and cost that are the very things you want to look at, a Danish Web site called runrepeat.com has a research to tell you the numbers from nearly 135,000 consumer reviews it gathered over a year, along with the suggested retail price of most of the popular brands.
    The biggest surprise: The higher the price, the lower the rating in many cases. In fact, the 10 most expensive running shoes, with an average list price of $181 per pair, were rated 8.1 percent lower than the 10 cheapest models (average price $61).
"If money is a matter to you, you will not get more in expensive running shoes," says the Web site’s founder, Jens Jakob Andersen. "Affordable mid-range running shoes are very nearly the same as expensive running shoes."
    That doesn’t mean that you should buy $15 running shoes at a department store. Those will almost surely cause you injuries. But Andersen believes that running shoe makers have poured so much money into marketing in their battle for a slice of a multibillion-dollar market that we don’t know what’s real any longer.
    "When you spend more, you expect more," Andersen says in trying to explain why expensive shoes may have disappointed some purchasers. "... But you should not expect to be less satisfied spending more money."
    Runrepeat bills itself as the Yelp of running shoes. Andersen says he takes no money from any company, funding the site himself. There are no ads.
    So which brands come out on top? Skechers, Saucony and Vibram Five Fingers took top three, while Reebok, Adidas and Hoka One One brought up the rear.
    "What Skechers are doing great is that they don’t do the really high price running shoes," Andersen says. "They are the running shoe brand for moms."
