Are your running shoes "dead" at 500 miles? Many runners lose sleep over the famous mileage rule, treating it as a non-negotiable expiration date. In this episode, we deconstruct the infamous 300 to 500-mile myth and expose how the running industry's business model of planned obsolescence has influenced this idea. We'll dive into the real science of shoe breakdown—from midsole compression to a runner's unique biomechanics—to uncover why a one-size-fits-all mileage rule is deeply flawed.

Instead of a number, we give you the practical tools to know when a shoe is truly worn out. Learn the key signs of fatigue and discover why your body is the ultimate sensor for shoe health. We also explore the proven benefits of a shoe rotation for extending the life of your gear and reducing your risk of injury. Join us to change your mindset, save money, and gain a new perspective on your most essential piece of running equipment.
