Matt and Andrea work through a range of shoes they've been testing, sharing thoughts on the direction Saucony and Brooks are heading, Andrea's track spike adventures, and a mix of recent pickups including the Asics Kayano 33 and On Cloudmonster Hyper LS. The conversation then shifts to a broader question: whether the way we currently categorize running shoes has gotten overcomplicated, using the Brooks Hyperion Max 4, Mizuno Hyperwarp Pro, Saucony Endorphin Pro 5, Endorphin Azura, and more as jumping-off points for discussion. What do you think? How do you categorize shoes? We'd love feedback! Email us at [email protected].

Matt is joined by Dr. Iain Hunter of Brigham Young University's Exercise Science department for an evidence-based deep dive into the science of super shoes. Drawing on his own research, Dr. Hunter explores the wide variability in how runners respond to plated footwear and tackles the practical questions runners are asking — whether super shoes are right for everyone, how to find the right fit, and how to integrate them wisely into training. They also dig into what the research says about tendon health, trail super shoes, and maintaining foot and calf strength.

Dr. Hunter completed a mathematics education degree with a coaching minor at BYU followed by a Master's of Education in coaching. His interests in biomechanics grew during his master's degree which led him to continue education with a PhD in Health and Human Performance at Oregon State University. He teaches biomechanics while working with USA Track and Field applying his research to elite distance runners.
