Run on a speedway in Monza, Italy, Breaking2 debuted the Nike VaporFly 4%, a pioneering running shoe worn by Eliud Kipchoge, Lelisa Desisa and Zersenay Tadese, born from deep scientific research into the limits of athletic potential, and how footwear can affect running efficiency. This includes baseline assessments, consideration of material elements, such as cushioning, and highly technical physical capacity like critical velocity.
“We look at variables related to a runners' stride, impact and heart rate to understand how footwear affects their performance. The longer you run above your threshold, the more quickly you're going to deplete your energy source,” explains Matthew Nurse, VP, NXT Sport Research Lab. “We can measure an athlete's oxygen consumption to understand their running efficiency (RE), and their maximum aerobic capacity (VO2max). This helps us understand capacity and efficiency. Think about it as the size of your gas tank, and the miles per gallon you get out of that gas tank. In our research, we want to understand what that threshold is for how fast you're going to deplete, or replenish, your reserves.”
The idea is that if you can help keep the reserves up, an athlete can go longer and faster. The solution is far more complex.
