In this episode of the Foot and Ankle podcast, host Alex Murray talks with Professor Gabriel Moisan to explore the complexities of custom foot orthotics and the underlying research.
They discuss the mechanisms of how orthotics work, the variability in patient responses, and the importance of individualized treatment plans. Gabriel shares insights from his clinical practice, emphasizing the need for a bottom-up approach in research, figuring out the how and why foot orthoses work, before if they work clinically for specific conditions and patient and the potential for predicting patient responses to orthotics.
They also delve into the complexities of foot orthotic design and management, particularly:

Alex is joined by Dr Doug Richie, Podiatrist and Surgeon from Los Angeles and the inventor of the Richie Brace, an ankle foot orthoses.
They talk about everything collapsing flatfoot including:
- The latest clinical name Progressive Collapsing Flatfoot Deformity (replacing adult acquired flatfoot deformity and posterior tibial tendon dysfunction) and what this means for our understanding of the condition.
- The difference between the collapsing flatfoot and posterior tibial tendon pathology
- Diagnosis, clinical tests and communicating the condition to patients
- Treatment, including why we need to aggressively manage people as early as possible
- Discuss Doug's clinical experience as both a physician and surgeon
A perfect accompaniment to our previous episode with Dr Peter Malliaras discussing Posterior Tibial Tendinopathy.
About Douh:
Dr. Richie is a Clinical Associate Professor at the California School of Podiatric Medicine.

Alex is joined by Dr Andy Bridgen PhD, Podiatrist and Senior Lecturer at the University of Huddersfield in the UK.
They talk about Andy's PhD thesis, exploring how Podiatrists in the UK utilise evidence in musculoskeletal practice, namely managing people with foot orthoses. The spoiler being, there isn't a consensus on how to use evidence in practice, nor, a significant body of evidence to draw upon.
They discuss the results in detail, what this means for the profession of Podiatry and the future of clinical practice.
About Andy:
Dr Andy Bridgen is a Senior Lecturer in the Division of Podaitry and Clinical Sciences and joined the University of Huddersfield in 2004. After qualiying as a podiatrist in 1995 he worked in the NHS working in MSK podiatry. He completed an MSc in Sports and Exercise Injury Management in 2006. In August 2017 he completed his PhD entitled 'A hermeneutic enquiry into how MSK podiatrists interpret and use evidence in practice'.

Alex is joined by Prof Peter Malliaras, a Physiotherapist and world renowned tendon researcher from Melbourne to talk about posterior tibial tendinopathy.
A not so often talked about tendon, but a common condition seen in foot and ankle practice, they talk through the specifics of managing difficult cases, considerations for exercise and rehabilitation and managing the person.
About Peter:
Peter Malliaras is a physiotherapist and researcher from Melbourne, Australia specializing in tendinopathy. In 2006 he completed his PhD in tendinopathy identifying novel risk factors, and since has undertaken post doctoral research in the UK and Australia, and has co-authored over 100 peer review publications.
Currently, he is a Professor at Monash University Physiotherapy Department and involved in multiple funded tendinopathy research projects in Australia and internationally. His research focuses on understanding pain and neuromuscular impairments, and clinical trials testing the efficacy of exercise and other interventions in the management of tendinopathy. Peter maintains a strong clinical focus, specializing in the rehabilitationa and management of difficult tendinopathy cases and regularly consults to elite athletes. He sees about 30-40 tendinopathy patients per week and regularly consults to elite athletes.

Alex is joined by Darcy Dore, a Sports Podiatrist from Queensland to talk about how he utilises technology in clinical practice, specifically Zebris, point of care ultrasound (POCUS), shockwave and Alter-G treadmills.
They talk through the pros and cons of each, how their use has impacted Darcy's clinical practice and who might benefit the most from their use.
About Darcy:
Darcy is a MSK focused podiatrist that consults out of FootFaults/RunClinic in Brisbane QLD. He has completed a post graduate diploma in Sports Medicine and utilises point of care ultrasound clinically. He is passionate about the benefits of using data to inform clinical reasoning and assist his clients with their goals.

Alex is joined by Anja Behling, a Biomechanist and PhD Candidate to discuss her latest paper "Chasing footprints in time - reframing our understanding of human foot function in the context of current evidence and emerging insights".
Originally designed as a historical review of podiatric biomechanical theories to assist non-Podiatrists attempting to understand how we consider foot function, during the process of writing it developed into a paper highlighting the lack of empirical support for many ways we biomechanically consider the foot and how we treat it.
In this episode Alex picks Anja's brain on the lack of research for traditional theories, emerging new insights into foot and ankle function and together they work to figure out how we can best understand the foot and ankle with the current research available.
About Anja:
Anja is a PhD Candidate in foot and ankle biomechanics working under the supervision of Podiatrist and foot biomechanics researcher Dr Luke Kelly at the University of Queensland and is co-advised by Dr Michael Rainbow at Queen’s University in Kingston, Canada. Originally completing a bachelors degree in biomechanics from Deutsche Sporthochschule Koln in Germany, she went on to complete a Masters of Performance Analysis and work alongside another juggernaut in biomechanics foot(wear) research, Dr Benno Nigg. With 9 current publications, including what I'd consider a seminal paper in foot and ankle podiatric biomechanics, she's someone I feel safe saying is worth watching her work in the future."
Alex is joined by Michael Nitschke, a Sports Podiatrist and Athletics coach to discuss the concept of coaching in clinical practice, for both our athletic and non-athletic population, exercise prescription and how our role moves beyond 'fixing' patients to guiding them back to better health and performance.
About Michael:
Michael graduated with a Bachelor of Podiatry from the University of South Australia (2006) and is a certified Sports Podiatrist (APodA 2017). He has practiced for 15 years in the field of Sports Podiatry with a primary emphasis on reducing running related injury risk via education on training, recovery, strength & conditioning, biomechanics, neuromuscular re-education and footwear selection.
Michael has competed in athletics for over 2 decades, and now continues to work in athletics via coaching middle-long distance runners (Level II advanced MD/LD coach - Athletics Australia) at the Adelaide University Athletics Club and head coach of the Adelaide Milers Crew. He also makes time to train and compete himself both on the track & road running events.
More recently he has begun part-time research where the focus is looking at the training characteristics of elite and recreational runners and the association with performance and sustainability, along with investigating training pace/critical pace and track running performance prediction.
Michael is a co-host of the monthly Shoe Geeks Podcast via the Inside Running Podcast with fellow runners/shoe geeks Julian Spence (The Running Company - Geelong) & Thomas Do Canto (Pinnacle Sports Podiatry).
Alex is joined by Travis to discuss the murky world of injury prevention literature and how we can help our patients avoid future injury.
About Travis:
Dr Travis Pollen, PhD, is a personal trainer, author, and Assistant Professor of Exercise Science. Over his 10-year personal training career, he’s trained professional athletes, senior citizens, and everyone in between. He’s on a mission to bridge the gap between rehabilitation and performance. In addition to his doctorate in Health and Rehabilitation Sciences, Travis has a master’s degree in Biomechanics and Movement Science. He’s previously held two American records in Paralympic swimming.
