The foot is a multi-planar moving structure.

In this twisted plate visual, you can see how how forces are absorbed & transferred through the foot.

The arch untwists to absorb shock & then twists up to become rigid once weight is offloaded.

(slow- mo video below) Image
Here’s a slow-mo video of the Twisted Plate mechanism in action, while running
Why is this important?

Modern shoes are taking this mechanism away.
There are 3 main ways that modern shoes prevent this crucial, multi-planar movement:

1. Single-plane movement restriction
2. Shunting of the biomechanics of the 3 arches
3. Reduction of big toe independence
1. Modern shoes keep your feet restricted to a single plane of movement.

Your shoes should be able to ‘twist’

However, due to the construction of the sole of most shoes, flexibility is restricted to allow a single plane of flexion/extension at the front 1/3 of the shoe

2. Modern shoes have Arch Supports, which block the arches’ ability to cycle through pronation & supination

The arch support is a physical ‘block’ preventing natural foot biomechanics Image
3. Modern Shoes have a narrow, pointed toe box

This restricts movement within the toes (mostly the Big Toe)

The Big Toe is responsible for maintaining a strong, resilient medial arch

When independent functionality of the big toe is lost, the twisted plate mechanism is lost Image
Pronation is a necessary aspect of this twisted plate mechanism

Pronation is a ‘compression & rebound’ reaction
However, OVER-Pronation is an extremely common problem

Over-pronation dysfunction stems from the 3 reasons listed above
When you restrict the natural biomechanics of the feet,
the muscles within the feet become very weak.
The solution?

-Re-Train your feet to move how they were designed

-Place your feet within an environment (shoes) in which natural biomechanics are not restricted
Re-Training the feet is my area of expertise

Since 2016 I’ve worked with 100s of clients & patients in PT clinics & through online coaching

I take them through a process of re-training their foundation to function as it was intended

The results have been life changing

You may have never though about “training your feet”

But you should! They’re the foundation of your entire body!

I guarantee the shoes you’re wearing are damaging your health

Modern shoes weaken your arches, bind your toes together, & wreak havoc on your posture

Here’s an in-depth explanation 🧵

(Healthy Shoe list included) Image
Modern shoes go against the laws of human design

I’m not just talking about high heels..

Even Nikes, Addidas, New Balance, Hokas..etc are progressively damaging your feet
There are four main negative features of modern shoes

1. Narrow Toe Box
2. Elevation of the Heel
3. Artificial Arch Support
4. Maximally Cushioned Soles Image

Children’s feet are most susceptible to the damaging effects of modern footwear

Feet do not fully develop until the age of 12

Until then, their feet are extremely moldable

Here’s exactly what you need to know in order to keep your child’s feet healthy🧵 (Shoe list included)
When a child is born they have 22 bones within each foot.

By the age of Three, the number of bones doubles.

During this period of time, the bones are not fully hardened, & the child’s feet are incredibly malleable. Image
The arch-building process starts when toddlers begin assisted standing & continues when they begin walking.

No child is born with arches - every single arch is built.

Foam rolling is not that great for increasing mobility.

Foam rolling does NOT
“release fascia,”
or “break down scar tissue,”
or “make your muscles longer.”
🧵 Image
The premise of foam rolling is adding pressure to muscle & soft tissue
- essentially a self-massage
Manipulating muscle with pressure, whether its massage, foam rolling, etc., temporarily changes the resting tone of a muscle via neural stimulation.

Here’s why I personally do NOT recommend heavy quad extensions to my clients 🧵

-I base this off of basic human biomechanics Image
-Quad extensions are an “Open Chain” exercise

“Open Chain” vs “Closed Chain”

Open: feet are NOT planted on the ground

Closed: feet ARE planted on the ground
There are no real-world applications that require loading the knee with the feet in a free swinging position
