David Grey: Achilles Rehab and Why Most PTs Get the Foot Wrong

In this special throwback episode, we sit down with David Grey, founder of David Grey Rehab, an internationally respected coach and rehabilitation specialist known for his innovative approach to lower-limb biomechanics, foot function, Achilles rehab, and plyometrics. Based in Ireland and widely followed for his practical, clear, and repeatable systems, David brings a refreshing blend of deep biomechanical insight and open-minded clinical reasoning. 

David shares his philosophy on assessing the lower extremity, focusing less on strict protocols and more on identifying what’s missing, restoring foundational patterns, and helping athletes reclaim authentic, efficient movement. He breaks down why so many clinicians miss key components of foot and Achilles rehab, how to assess true foot mobility (not just ankle mobility), and why closed-chain mechanics are essential for lasting change. 

In this episode, we cover how David evaluates foot shape and calcaneal mobility, why midfoot movement is non-negotiable, and how to coach athletes through meaningful pronation and supination. He also walks through practical progressions for soleus and Achilles loading, tibial rotation, and plyometric readiness, including why most rehab programs fail to bridge the gap to the demands of sport. 

David’s approach combines biomechanics, sensory awareness, reactivity training, and a commitment to staying curious. His perspective on what clinicians get wrong, why open-chain foot drills often miss the mark, and how to progress from early isometrics to high-level plyos offers a masterclass for any sports physical therapist looking to elevate outcomes for foot, ankle, and Achilles patients.

Whether you’re a sports PT, performance coach, or athlete dealing with persistent lower-limb issues, this episode will challenge assumptions and give you practical frameworks you can implement immediately.

Watch now to learn how David Grey is redefining lower-limb rehab through movement, mechanical clarity, and openness to learning.
