- lyk 8y ago"Runners who improved their performance in Vaporflys and then switched to other shoes got slower. There were very few runners in our data who met this criterion: We counted just 24 such races. But these runners finished about 7 percent slower on average than they did while wearing the Vaporflys. (Of the 24 races, 17 races were slower, and 7 were faster.)"
