This episode is all about that max stack. With almost every shoe coming in with a midsole thicker than 30mm, it's becoming hard to define what "maximal" even means, but Nathan, Matt, and David will give it a shot. They take a look at the research on maximal shoes and how it applies to today's offerings. They also argue about what shoes even count as max-stack trainers these days (and what about once you get above 40mm?). They also explore the impact of today's shoes' large amount of cushioning on a runner's biomechanics. Finally, they discuss some of the latest findings on super shoes and how we should think about training in them.
