Walking is something most of us take for granted. We do it to get from A to B, we track our steps on our phones, we might even use it as a bit of exercise. But what if walking is far more than that? What if, quite literally, your life depends on it?

Dr Courtney Conley is an internationally recognised authority on foot mechanics and gait dynamics and the founder and creator of Gait Happens, which provides evidence-based foot education for athletes, movement professionals, and regular humans like you and me. She has over 25 years’ worth of clinical experience, and has worked with a wide variety of organisations, including New York Yankees, New York Giants and The San Francisco 49ers. Her first book Walk: Your Life Depends On It is a fantastic read, officially comes out on May 5th, 2026 and is available for pre-order right now.

In our conversation, we discuss why walking should be considered a physiological necessity, potentially on a par with sleeping and breathing, why Courtney believes that our feet are the most neglected part of our bodies and how modern footwear has put fashion ahead of function, with some serious unintended consequences. We also discuss why our big toe might be the most important joint in our body, how our walking speed can predict our future health, and why even a small increase in daily steps can dramatically reduce your risk of cancer, dementia and depression.

Throughout our conversation, Courtney shares plenty of practical advice, such as simple foot assessments you can do at home, easy exercises to build strength and mobility, and a clear framework for choosing better footwear for yourself and your children.

Courtney wants to help as many people as possible reclaim the true function of their feet. Her message is one of hope and empowerment and I am quite sure that this conversation will give you a different perspective about the importance of walking and inspire you to start taking a bit more care of your feet.
