Examining the role of footwear cushion in preventing running injuries
Michael Ryan C. Ped (C)
Webinar : Sept 14-25
Discussion: Sept 28- Oct 2
CEPs: 5 structured
The prevention of running injuries has been a goal of sports medicine for the past 25 years.1 Various prevention frameworks have been proposed over this time-span with only limited success, leading to simply more questions than pragmatic and safer training approaches for runners.2-4
Footwear has long been considered an important component to preventing injuries in runners. For nearly every risk factor for injury there has been a corresponding footwear design to mitigate that risk. Over-pronation, impact loads, and heel strike pattern have each been addressed through the introduction of stabilizing elements8 (dual-density mid-sole, thermo-plastic shank), shock-absorbing materials9, and minimalist designs10 respectively. Recently, the addition of another functional element, the stiff forefoot rocker, has shown to reduce stress on selected lower extremity tissues suggesting it may also serve an injury prevention role.11 12
This talk will focus on a research study conducted in 2019 that evaluated the clinical effects of a new protective running footwear design incorporating a new adaptive cushioning mid-sole with stronger forefoot rocker.

First Ray Insufficiencies: Myths & Misconceptions

“The most debated concept about foot and ankle pathology may be the role of instability of the first ray…”
Corinne Van Beek, MD and Justin Greisberg, MD Mobility of the First Ray:Review Article Foot & Ankle International/Vol. 32, No. 9/September 2011
How does instability of the first ray contribute to the pathomechanics of hallux abductovalgus, hallux rigidus, functional hallux limitus and metatarsalgia?
How much of your current knowledge about the first ray is based upon
accepted dogma rather than good science?
Many myths and misconceptions regarding the mechanics of the first ray exist today and often lead the practitioner to implement treatments that ultimately fail.
Here are common myths about the first ray which will be discussed in this webinar:
- Hypermobility of the first ray is a theoretical condition of excessive dorsiflexion motion of the first metatarsal during dynamic gait
- Clinical measures of hypermobility of the first ray are commonly performed in a static off-weight bearing condition which will not engage multiple forces which occur during dynamic gait
- Static measures of first ray mobility do not predict first ray hypermobility during gait
- Stability of the first ray is dependent upon specific anatomic structures located at the first metatarsophalangeal joint (1st MTPJ), providing static or dynamic restraint of motion, or both.
- Hallux abductovalgus (HAV) deformity is the only pathology of the human foot which demonstrates excessive dorsal mobility of the first ray with static exam, and this hypermobility reduces or vanishes when the first metatarsal is re-aligned over the sesamoids.
- Metatarsus primus elevatus (MPE) is a static radiographic measure which does not predict load bearing capacity of the first metatarsal during gait
- Patients with evidence of MPE do not show excessive mobility of the first ray with static exam.
- Metatarsus primus elevatus is the result of progressive degenerative arthritis and progressive plantar flexion contracture of the hallux seen in hallux rigidus
- Most people demonstrate greater range of motion of dorsiflexion of the 1st MTPJ off weight bearing compared to range of motion weight bearing and during dynamic gait.
- Studies of patients with evidence of functional hallux limitus with static examination will show normal extension of the 1st MTPJ during dynamic gait
In this presentation, Dr Doug Richie will uncover these myths and reveal the sound science which can change current strategies to treat common pathologies in the human foot.

He completed a post-graduate Podiatric Surgical Residency Program at Western Medical Center in Orange County, California. Richie is certified by the American Board of Foot and Ankle Surgery and is a Fellow of the American College of Foot and Ankle Surgeons.
Richie is also a Fellow and Past President of the American Academy of Podiatric Sports Medicine. His research interests have included studying prevention and treatment of the ankle sprain as well as the pathomechanics of flatfoot deformity. Richie is a two-time recipient of the American Podiatric Medical Association Research Award and has also received the Richard Schuster Biomechanics award from the American Podiatric Medical Association.
Richie holds five US patents on technologies regarding manufacture of footwear, ankle brace design and foot orthotic design. He recently retired from 38 years of clinical practice located in Seal Beach, California.
With faculty appointments at the California School of Podiatric Medicine and at Western University School of Podiatric Medicine, Dr. Richie devotes his time to teaching, original research and writing. His recently completed book “The Pathomechanics of Common Foot Disorders” will be published in Fall, 2020 by Springer Nature.
