The plantar fascia is far more than a passive arch support—it's a dynamic tissue that helps your foot absorb, store, and return energy with every step. In this solo episode, Dr. Emily Splichal explores the anatomy and function of the plantar fascia, explaining its three bands, layered structure, and connection to the Achilles tendon. She discusses how the foot transitions from a mobile shock absorber to a stable lever during movement, and why arch compression and forefoot mobility are essential for efficient walking and running. The episode also dives into running biomechanics, ground reaction forces, injury prevention, and a fascinating real-world case study involving Cirque du Soleil performers that highlights how surface vibration can influence movement and injury risk.
