![]() They translate this to a 3.4% reduction in marathon time. The paper found a 4% lower energetic cost for the super shoes. The researchers used various standard breathing and blood tests to measure the “energetic cost” of these efforts. They had the athletes run 5-minute intervals in three shoes: a super shoe prototype from Nike and two standard racing shoes. (You know running loves numbers.) One 2018 paper collected controlled data from 18 serious male athletes. This question is amenable to very detailed data collection. The number of people qualifying for the Olympic Trials in the marathon has almost doubled between 20 the qualifying time hasn’t changed, but the shoes have. One clear indication that these shoes matter is that professional road racing times have come down dramatically during this period. ![]() If you’re not … it’s a good time to start, since (spoiler alert) with these shoes you can start faster. If you’re a runner, hopefully this clears it up. So today we’re going to do the data on super shoes. This really felt like a question for data. One commenter told me (nicely) that her husband feels the research does not support the value of these shoes, or that only the Nike versions work. ![]() When I posted about them, I got questions, and also some skepticism. I talked about this evolution a bit on a podcast last week with the great Ali Feller.Īs part of this very intense hobby, I recently acquired a pair of “super shoes” - the new-technology racing shoes that supposedly make you faster. My interest in this activity has ebbed and flowed over the years, but at the moment I would say I take it somewhat seriously (my husband described it recently as a “very intense hobby”). If you follow me on Instagram, you probably get a sense that I like to run. Or, rather, my one non-work, non-family interest: running. Today’s post, then, is inspired by my own interests and hobbies outside of parenting. Usually I take this to mean “data about parenting.” But an alternative interpretation is “data for parents.” And under that frame, it seems useful to recognize that parents are also people people with interests and hobbies and goals that range beyond parenting (yes! It’s true!).
