The answer lies in a biomechanical blind spot: high-tech footwear isn't just returning energy, it's rewriting your running form in real-time. In this episode, we unpack new research revealing how stack heights and space-age foams interact with your unique stride. Tune in to find out if the future of the sport means retraining your gait just to unlock the true speed hiding in your shoes.

Scientific paradigms and culture trends have been adopted and dismissed. We look at what the science tells us in 2026 so that you know what to think about the next time you look at the shoe wall in a running store.


Also, some mythbusting.
