Your Feet Are Getting Weaker. Here's Why. | Dr. Mark Wallen What if the root cause of your knee pain, poor balance, declining mobility, and even faster aging starts with something you rarely think about... your feet? For decades, medicine treated the foot as an isolated body part—something to cushion, brace, inject, or surgically repair. But after spending more than 40 years as a podiatric surgeon, Dr. Mark Wallen began questioning everything he thought he knew. In this eye-opening conversation, Dr. Wallen shares why modern footwear may be weakening our feet, how foot dysfunction impacts the entire kinetic chain, and why strengthening the foundation of your body could be one of the most overlooked keys to longevity, athletic performance, injury prevention, and healthy aging. We dive into barefoot training, toe spacers, orthotics, balance, posture, foot mobility, aging, athletic performance, and the surprising mistakes millions of people make every day that may be contributing to chronic pain and movement dysfunction. Whether you're an athlete, weekend warrior, healthcare provider, parent, or simply someone who wants to stay active for life, this episode may completely change how you think about your feet.
