Sharon has been a serious runner for six years. She has completed three marathons and several shorter races. Each week she runs about 20 miles.

Her favorite shoes? A $25 pair of Champion shoes she bought at Target. “I like running in simple shoes,” she said, “The more you pay, the more trouble you get.” She is right. Money often buys higher-quality goods, but not when it comes to running shoes.

Over the last forty years, running has been popular as a leisure (闲暇的) sport. In 2009, 476,000 runners took part in a marathon. In 1976, the number was just 25,000. Sales of running shoes reached a record $ 2.36 billion in 2009, 60 percent more than ten years earlier.

But some of those dollars may not have been well spent. In 2007, Scottish researchers tested running shoes at three price levels, ranging from $80 to $150, and found that low-cost and mid-cost shoes within the same brand protected runners’ feet just as well as high-cost ones, sometimes even better.

“The common idea is that if you pay more, you will get better shoes,” said Abboud, director of the Institute of Motion Analysis and Research at the University of Dundee in Scotland, “Our research did not show that.” Professor Abboud and his colleagues have just completed a similar study, as not yet published, with nearly the same results.

If you want to run well and run safely, consider fit first and price last. “You want a shoe that helps you keep a balanced position,” said Mark Montgomery, manager of the JackRabbit Sports store in Union Square in New York, “A more expensive shoe is not always the solution.”

“The less you think about a shoe, the better,” said Ms Bakoul, a marathoner.
