Carbon-Plated Running Shoes: Faster… But At What Cost? – With Physio Andy Smith

In this episode of the BeBattle Ready podcast, host Simon Ward explores the growing use of carbon-plated running shoes in endurance sports, particularly among triathletes and marathon runners. While these shoes promise faster times, improved efficiency, and quicker recovery, physiotherapist and elite runner Andy Smith reveals a critical trade-off: they shift biomechanical stress upward, increasing the risk of bone stress injuries in the femur, pelvis, and sacrum. Drawing on clinical observations and research, Smith explains how the reduced ankle dorsiflexion and altered gait mechanics in these shoes decrease load on the Achilles and calves but increase demand on the hip, core, and posterior chain. He emphasizes that the shoes don't eliminate injury risk—they simply relocate it. The key takeaway? Strength and preparation must precede shoe adoption. Without foundational strength in the calves, hips, and core, runners are more vulnerable to injury when using these high-performance shoes. Smith advocates for a gradual transition, using the shoes sparingly for races and training sessions, and recommends a prehab program focused on hip abductors, calf raises, core control, and thoracic mobility. The episode concludes with a clear action plan: before investing in carbon-plated shoes, runners should undergo a strength assessment, build a targeted prehab routine, and introduce the shoes slowly—starting with strides and light sessions. Smith stresses that the shoes are not a substitute for strength and that their benefits are only realized when the body is prepared to handle the new mechanical demands. The conversation underscores a broader theme: technological advancement in sport must be paired with physiological resilience. While the shoes are here to stay, their use should be strategic, informed, and grounded in long-term durability rather than short-term performance gains.
