Nate, Matt, and DJ are joined Cory Hofmann from Saucony for a deep dive into the world of shoe testing. Cory gives us an inside look at how Saucony tests the biomechanical and physiological impact of their shoes on runners. He also helps us define some oft-misunderstood scientific terms like running power, metabolic cost, running economy, VO2 Max, and more. Cory Hofmann is a Performance Engineer at Saucony research laboratory, testing almost every aspect of their shoe: fit, durability, mechanical properties, etc. Cory specializes in testing and measuring running shoe performance, focusing on biomechanics and physiology.
