    PORTLAND, Ore. – Nike’s new Zoom Vaporfly 4% running shoe earned its name, according to a study from researchers at the University of Colorado.

    The study was published on Nov. 16 and says the shoes lowered the energetic cost of running on their test subjects by 4 percent on average.

    American runner Shalane Flanagan recently won the New York City Marathon wearing the running shoes and Kenyan runner Eliud Kipchoge took part in Nike’s Breaking 2 project while wearing the 4%s. He finished the marathon distance in 2 hours and 25 seconds.

    Researchers tested the shoes on 18 high-caliber athletes who ran six, five-minute trials. They wore different shoes to compare their results.

    The results showed the Nike Zoom Vaporfly 4% shoes reduced the energetic cost of running in all the test subjects.

    Comparatively, the energetic cost of running in the 4%s was 4 percent lower than the other shoes used in the study, the Adidas adizero Adios BOOST 2 and the Nike Zoom Streak 6.

    The Nike Zoom Vaporfly 4%s cost $250 on Nike’s website.
