According to a recent study performed at CU Boulder, the Nike Zoom VaporFly 4% actually improves marathon efficiency over other top models. The study showed that runners saw an approximate 4 percent increase in efficiency while wearing Nike’s new top performance silhouette – hence the name Zoom VaporFly 4%. The study included comparisons of other top Nike models as well as shoes from other brands. The full details of the study can be seen on Wired. However, it has not taken the Swoosh brand long to proudly display their findings, as it has already taken to Instagram with the post below.
We’re not saying they’re not the most talented marathon runners in the world, or that they don’t deserve all those wins and records they earned this year. All we’re saying is: With the success our elite athletes have had wearing the Nike Zoom Vaporfly 4%, not a single one of them is willing to give their pairs back.
