Welcome to the MASS Posture Custom Foot Orthotics Podcast, where we explore the science, biomechanics, and real‑world outcomes behind custom flexible orthotics made in the MASS position — that’s Maximal Arch Supination (soo puh NAY shun) Stabilization.
If you’ve ever wondered why some orthotics feel amazing while others end up in a drawer, or why rigid devices often create more problems than they solve, you’re in the right place.
Today’s episode covers four major topics:
MASS Posture vs. Traditional Orthotics: A Side‑by‑Side Breakdown
Support vs. Correction vs. Restoration
Why Rigid Orthotics Often Cause More Problems
The Science Behind Flexible, Full‑Contact Support — Plus Real‑World Outcomes
Let’s dive in.
Most traditional orthotics are built using a subtalar neutral model — a position that’s neither fully pronated nor fully supinated. It’s a compromise position, and the resulting orthotic is usually designed to control motion rather than restore optimal function.
Instead of capturing the foot in a partially collapsed state, MASS orthotics capture the foot in its maximal functional posture — the highest, strongest, most structurally efficient arch the foot can achieve without strain.
This position is not artificially imposed; it’s the foot’s true anatomical potential.
The orthotic is then built to support that posture dynamically, not force it rigidly.
Often rigid
Built to block pronation
Designed around pathology control
Flexible
Full‑contact
Designed to restore natural biomechanics
The result is a device that works with the foot, not against it.
These three words get thrown around a lot, but they’re not interchangeable.
Support
Support simply means holding the foot up. Many orthotics do this — but often in a passive, rigid way.
Correction
Correction implies forcing the foot into a position it cannot achieve on its own. This is where discomfort, compensation, and long‑term issues often arise.
Restoration
Restoration is the MASS philosophy.
It means:
Identifying the foot’s optimal functional posture
Capturing that posture
Supporting it dynamically so the foot can return to its natural movement pattern
Restoration is active, not passive.
It encourages the foot to behave the way it was designed to — absorbing shock, storing energy, and releasing it efficiently.
Rigid orthotics were originally designed under the assumption that the foot needed to be controlled. But the foot is a spring — a dynamic, adaptable structure with 26 bones, 33 joints, and over 100 muscles, tendons, and ligaments.
When you immobilize a spring, several things happen:
Shock absorption decreases
Forces shift upward into the knees, hips, and lower back
Muscles weaken from lack of engagement
Compensation patterns develop
Many patients report:
Heel pain
Knee pain
Hip tightness
Lower‑back discomfort
A feeling of “walking on a hard block”
Rigid orthotics often treat symptoms while creating new ones.
Flexible MASS Posture orthotics do the opposite.
They allow the foot to move — but in the right posture — restoring natural shock absorption and energy return.
A MASS Posture orthotic is designed to:
Match the exact contour of the foot in its optimal posture
Maintain full contact from heel to toe
Flex with the foot, not fight it
Store and return energy like a leaf spring
This full‑contact design distributes pressure evenly, reduces hotspots, and supports the entire kinetic chain.
A flexible orthotic:
Absorbs impact
Encourages natural pronation and supination
Allows the arch to load and unload
Reduces stress on joints
Promotes healthier gait mechanics
It’s not about stopping motion — it’s about guiding it.
Across clinics using MASS Posture orthotics, the stories are remarkably consistent:
Case Example: Chronic Plantar Fasciitis
A patient who tried three different rigid orthotics finally switched to a MASS Posture device. Within weeks, pain decreased dramatically because the orthotic supported the fascia in its elongated, functional position rather than bracing it rigidly.
Case Example: Knee and Hip Pain
A runner with chronic knee pain found that restoring proper foot posture reduced rotational stress up the chain. Flexible support allowed the foot to load correctly, improving alignment naturally.
Case Example: Flat Feet
Patients with flexible flat feet often see the most dramatic changes. When the arch is restored to its maximal functional height, the entire foot becomes more efficient — and symptoms often improve rapidly.
These aren’t isolated stories. They reflect a consistent pattern:
When you restore the foot’s natural posture, the body responds.
Thanks for joining us on the MASS Posture Custom Foot Orthotics Podcast. Today we explored why MASS Posture orthotics represent a major shift in foot biomechanics — moving from rigid control to dynamic restoration.
