The Truth about Midsole Foams (ft. Geoff Burns) | Sub 2 (hours)

In special extended episode of the Doctors of Running Podcast, Nate & Matt discuss shoe foams and biomechanics with physiologist and researcher Dr. Geoff Burns. In this episode, Geoff educates us about the effects of different shoe properties on our biomechanics. He also explains how biomechanics change while running at different paces. Dr. Burns then takes us on a deep dive into the history, properties, and durability of common running shoe midole foams. Ever wondered what the difference between EVA, TPU, and PEBA is? Dr. Burns has the answers.
