Running shoe industry expert David Jewell of Runningshoeinsight.com stood out on the Ironman World Championship run course for the eighth year in a row to collect data on which running shoes the world’s best triathletes are wearing. For the first time ever, he counted the shoes during the final, more-spread-out mile of the marathon instead of the first to ensure a higher level of accuracy. After dethroning Asics in 2017, Hoka One One once again prevailed as the most-worn brand—capturing the feet of 17.7% of the athletes. A big mover was Nike in second place, going from 5.7% in 2017 to 14.9% in 2018.
