In seven of the 11 subjects, the difference in running economy between their best road shoe and their best spike was greater than 0.5 percent, which is substantial. There was one other wrinkle in the data, which was individual variation. So a typical 4:00.0 miler in the old spikes might expect to run 3:56.8 in the new ones-“corrected for inflation,” as Burns puts it. The calculations are trickier at track-running speeds than they are for marathoners (for reasons explained here), but a reasonable estimate is that improving your running economy by 1 percent will increase your racing speed by about two-thirds of a percent. Olympic and Paralympic Committee and co-author of Joubert’s study, to run some numbers for me. What does a 2 percent improvement in economy translate to? I asked Geoff Burns, a physiologist with the U.S. Heavily cushioned road shoes with stack height of greater than 25 millimeters are banned for track races in international competition, Joubert and his colleagues point out, but permitted in high school and college racing. On average, each runner’s best spike was roughly equivalent to their best road shoe: the added cushioning in the road shoes seems to make up for their extra weight. The main result (which, for the record, has not yet undergone peer review as a conference presentation) was that the super spikes improved running economy by about 2 percent compared to the traditional spike. For each shoe, they tested running economy-a measure of how much oxygen is consumed to sustain a given pace-on two occasions, at 6:00 mile pace for the men and 6:53 pace for the women. They recruited 11 distance runners to come to the lab and test seven different shoes: three road supershoes, one traditional racing flat, two track super spikes, and one traditional track spike. Austin State University) decided to fill this gap. ![]() Edward’s University in Austin (and formerly of Stephen F. Anecdotal evidence strongly suggested that the new spikes were indeed faster than older versions, but no one had yet quantified the effect.Ī group led by Dustin Joubert of St. Finally, Some Data on Super Spikesīack in 2021, I wrote about the new generation of track spikes, which like the now-ubiquitous road running supershoes combine a stiff plate with a layer of ultralight and resilient cushioning. In the coming days, I’m going to share a few highlights, starting with the latest findings on running shoes: how they work, what to train in, and how to pick the best model for you. In more than 1,500 presentations, they offered a peek at new and forthcoming data on the science of health and performance. Earlier this month, thousands of sports scientists gathered in Denver for the American College of Sports Medicine’s annual mega-conference.
