#128 – Irene Davis, Ph.D.: The evolution of the foot, running injuries, and minimalist shoes

Human running mechanics and the evolution of footwear define the core of natural movement. Humans evolved as endurance runners with feet designed for natural movement, yet modern cushioned shoes often disrupt this biomechanical efficiency. Dr. Irene Davis, a biomechanics expert, explains that traditional motion-control and cushioned footwear may weaken intrinsic foot muscles and alter natural gait patterns, leading to increased injury rates. Instead of relying on extrinsic support like orthotics, strengthening the foot’s intrinsic muscles and transitioning to minimalist footwear can restore natural shock attenuation. Gait retraining—specifically shifting from a heel-strike to a forefoot-strike pattern—significantly reduces loading rates and injury risk. Ultimately, prioritizing physical literacy and foot health from childhood, rather than relying on corrective gear, offers a more sustainable approach to long-term athletic performance and injury prevention.
