The Super Shoe study with Dustin Joubert, PhD | EP#322

Associate Professor Dustin Joubert of Stephen F. Austin State University discusses his study comparing seven carbon-plated "Super Shoes", and how runners and triathletes should interpret and use the results. We also discuss more informal testing that Dr Joubert is doing on a regular basis in his lab, including shoes not included in the study.    IN THIS EPISODE YOU'LL LEARN ABOUT: -What is a super shoe, what are the purported benefits, and the proposed mechanisms behind them?  -The Super Shoe study: protocol, shoes included, results and conclusions. Are the Nikes all-conquering?  -What does this mean for consumers? How should triathletes and runners go about selecting shoes for racing?  -Dr Joubert's informal testing, including the Adidas Adios Pro 2 and running in crocs!  -How do running economy benefits translate to performance benefits?  -What happens to the benefits from Super Shoes when running uphill or downhill?    SHOWNOTES: https://scientifictriathlon.com/tts322/   SCIENTIFIC TRIATHLON AND THAT TRIATHLON SHOW WEBPAGE: www.scientifictriathlon.com/podcast/   SPONSORS: ROKA - Exceptional quality triathlon wetsuits, trisuits, swimskins, goggles, performance sunglasses as well as prescription eyeglasses and sunglasses.  Online vision test for prescription updates and home try-on options available for eyeglasses.
