Dr Kim Hebert-Losier is leading the research into Nike's innovative vaporfly 4% and subsequent next % running shoes used to break the sub-2-hour marathon. We discuss what the shoe actually does and it's claimed benefits, and use evidence to discuss whether these will actually help you run faster.

61 | Nike Vaporfly with Dr Kim Hebert-Losier: Cheating or Innovation?
From the Performance Advantage blog · pavillaflores · 2020-11-05
The guest for this episode was Dr. Kim Hebert-Losier, a French Canadian sports scientist, specifically an applied biomechanics, senior lecturer in Waikato University in New Zealand. As said in the title, the main topic that they discussed was her research article, and its' information about Nike Vaporfly, and whether or not it was actually considered as a biomechanical doping shoes.
Dr. Kim's research paper titled 'Evidence of Variable Performance Responses to the Nike 4% shoes' was already complete, and would be considered as a pre print, which means that it was publicly published, and only lacked the peer-review.
She was asked on her opinion whether or not she thought that the shoes improved performance and she said "If you look at the evidence, it's kind of hard not to say that they improve performance."
Dr. Will also asked her "What did you want to achieve by doing this paper?" Dr. Kim explained that all of the current research at that time (before she did the paper) was all in elite, or highly trained runners, which means that the subjects of their tests were from a selected, relatively small sample compared to the actual number of consumers that were not necessarily elite runners. She also described that there a whole lot more recreational type of people than the elites from all of Nike's customers.
According to what Dr. Kim said, "I guess the main drive was to actually see if your more average day-to-day runners could improve with the Nike Vaporfly."
