The former world champion Jenny Simpson of the United States finished 11th in the 1,500 meters at this year’s world track and field championships in Beijing on Tuesday after losing her shoe in the final.
About halfway through the race, amid some jostling with other runners, Simpson was clipped from behind.
“I was jogging along with everyone else and I kind of paid the price for it,” Simpson said. “I got shoved into the traffic. My shoe even ripped, I got spiked bad enough, it totally ripped when it came off.
“It stayed part way on; it wasn’t the fault of not tying it tight enough or something.
