Fancy Running Shoes Really Do Seem to Make You Faster


Comments 15 comments   

For most of us, the best running shoe is whichever one feels the best when you run in it. But shoe companies have been claiming that certain shoes—especially Nike’s $250 Zoom Vaporfly 4%—save you so much energy that they actually make you faster. Now, we finally have data to answer that question, and it looks like Nike isn’t bluffing.

We have to be clear about the bias in this study: Nike funded it. But the experiments were carried out in a respected laboratory, Alex Hutchinson reports at Outside Online, and the results show that runners needed less oxygen, which means they weren’t working as hard. That translates to saving energy that you can use to push yourself to go faster. The full text of the study is available here.
