"As a nurse I spend all day on my feet and average about 16,000 steps per shift. I no longer have ankle, knee, or back pain. These are not an insole. They are something completely different."

Ali is one of thousands of healthcare workers who found this — and wants every colleague to know it exists.
We are here to bring the knowledge that Ali and thousands like her want to bring to every healthcare worker who hasn't heard it yet.
"There is nothing wrong with your feet. The hospital floor — and every other flat surface you stand on — is the problem."
The rest of this page will tell you WHY flat surfaces are a problem — and WHY Landing Gear has proven to be a solution that works for 95 out of 100 people.
And at the end — you will find how we are able to offer healthcare workers 30% off. Not as a promotion. As a partnership. You take the burden of spreading the word. We pass you the marketing cost directly. Everyone gets the knowledge. Everyone gets the opportunity to decide.
That is the agreement.
If You Have 30 Seconds
Your feet aren't the problem. The floor is. Two million years of evolution shaped your foot to navigate uneven terrain — rocks, soil, roots. Every step on that terrain sent a varied, three-dimensional signal that guided your foot through its full motion sequence. That signal told your body how to land, how to distribute force, how to move forward.
Flat ground sends no such signal. Concrete under linoleum delivers the same zero every time. Your foot arrives at each step waiting for information that never comes. The joint below your ankle — built to process that terrain signal — locks. Force that should be distributed through the kinetic chain travels straight up instead. Every step. All shift.
Landing Gear restores that signal. Not cushioning. Not arch support. The geometry the ground was always supposed to deliver. Independent 3D motion capture shows 9 out of 10 bodies move into correct mechanical range. Your body knows immediately.
95 out of 100 keep them. The other 5 get every cent back within 90 days.
If you are a medical professional — we encourage you to read the full page. There is clinical detail here you may not have encountered, and that your patients on hard floors would benefit from hearing.
After all — you are Florence Nightingale.
The evolutionary gap.
Your foot was shaped over 2 million years.
Flat floors arrived 200 years ago.
Your subtalar joint is still waiting for the terrain it evolved on.
Rocks, roots, soil, grass, sand — your subtalar joint learned to process 3D signals continuously.
Concrete, tile, hospital linoleum — all delivering the same zero-degree signal. Or rather, its absence.
Your foot isn't broken. Its environment changed.
Evolution can't catch industrialisation. Your foot still expects terrain variation — and it functions best when it gets that geometry back.
Your subtalar joint rotates on a diagonal axis — three planes at once. Flat geometry can't guide diagonal motion.
Modern ground sends the same signal every step: zero degrees. No variation. No feedback.
The peer-reviewed literature now agrees.
The industry has had it wrong.
In 2023, Behling et al. published a landmark study in Biological Reviews formally calling for the abandonment of the static arch support model — the premise the entire insole industry was built on. The field has been treating the wrong problem for over a century.
Landing Gear was built on the motion paradigm 20 years before this paper was published.
This is what Ali wants every healthcare worker to know:
Landing Gear TechnologySame Shoes. Same Floors.
Different Signal.
Protalus doesn't change your shoes or your environment. It RESTORES what the ground was always supposed to deliver — the 3D signal your subtalar joint (your foot's central steering hub) was designed to receive with every step.
At Heel Strike
Rear geometry slows eversion and guides the calcaneus into its natural rotational path — not a flat stop.
At Midstance
Medial geometry limits excessive rotation and re-engages stabiliser muscles that flat ground switched off.
At Toe-Off
Forefoot projection transfers energy through a neutral axis — restoring the elastic spring your step lost.
31 subjects. 3D motion capture.
Four conditions. One question.
Dr. Martyn R. Shorten, Ph.D. — former Director of the Nike Sport Research Laboratory, Technical Editor of the Journal of World Sports — conducted an independent motion capture study at BioMechanica LLC. The question: how many bodies move into correct mechanical range with each insole condition?
| Condition | Bodies in correct range | Result |
|---|---|---|
| Standard foam insole | 3 of 31 | 10% |
| Leading aftermarket insole | 6 of 31 | 19% |
| Landing Gear T-100 | 19 of 31 | 61% |
| Landing Gear M-100 | 28 of 31 | 90% |
Same 31 bodies. Starting deviation ranging from 2.8° to 22.3°. Wide variation in — consistent mechanical range out. The geometry doesn't push every body to the same fixed position. It compresses variability so force moves through the system correctly, step after step, shift after shift.
For the complete science — subtalar joint axis literature, Behling et al. methodology, the full study — read the science page.
Not Support. Landing Gear.
The insole industry built its products around one idea: prop up the arch. That is the support paradigm — it stops motion to feel stable. The problem is that your foot was designed to move. Landing Gear is built on a different idea entirely.
| Feature | Landing Gear — Protalus | Traditional Insoles |
|---|---|---|
| Approach | Guides motion on the correct axis — triplanar, dynamic | Stops motion to feel stable — single plane, passive |
| Geometry | Engineered to the 42°/16° subtalar joint axis — published science | Matches the static shape of the foot at rest — no axis correction |
| Motion | Triplanar — moves naturally with the body through all gait phases | Single-plane — up/down only, no rotational guidance |
| Calf pump | Heel strike restored — venous return pump firing correctly | Gait pattern unchanged — second heart still compromised |
| Energy | Elastic loading restored — energy returned at toe-off | Spring cycle blocked — every step costs, nothing returned |
| Proprioception | Directional cues reactivate stabiliser system | Flat signal — noisy, no directional information |
| Science basis | Motion paradigm — validated by Behling et al. 2023, Biological Reviews | Static arch paradigm — formally called for abandonment, Behling 2023 |
| Result | Motion restored — body reactivated, force distributed correctly | Motion frozen — system not landing correctly, bill moves up |
What healthcare workers say
about the floor.
4.8 · 99,000+ reviews · all on the same geometry · 95% would recommend
"Two weeks with Protalus and I'm walking without pain for the first time. These are not an insole. They are something completely different."
"I'm a registered nurse working 13-hour shifts with achilles tendinopathy. The first day I wore them, my pain was at least 90% improved. It nearly brought tears of joy."
"I'm a pharmacist on my feet most all day. Been suffering from plantar fasciitis for months. This is a total game changer. Improved each day to the point my feet don't hurt anymore."
"My husband is a nurse working 12-hour shifts. He called me 3 hours in to tell me how great his feet felt — and his back. Came home with NO complaints of pain. Worth every penny."
"I bought these for my wife, an RN. Years of being on her feet have taken their toll. She made me buy her another set. They have taken away her foot pain."
"I'm a nurse in the OR. On my feet all day on hard cement floors. The M-100 have been a knee and hip saver. After the 3rd day of using them, I didn't take any ibuprofen after my lunch break. I will add them to all of my shoes and boots now."
We are honoured to be part of your mission.
Our mission has always been that everyone should have the knowledge about what the flat surfaces we live on do to our bodies. That is why you find "Share My Story" and "Our Story" in the dropdown navigation under "All About Landing Gear."
It is an honour and privilege that so many of you have asked us to create a place where you can be the missionaries amongst healthcare workers. We are not asking you to persuade anyone to buy Protalus Landing Gear — that is a choice everyone needs to make for themselves. But we are honoured to be part of your mission — and instead of us spending almost $20 per pair on marketing our message, we want to contribute that as a cost saving to you for being part of this mission.
Like Ali, James, Maria — make your own testimonial and post it to your site, your groups, your community. Or use one of the options below as a starting point, edit it, shorten it, or use as is. Above all — tag five colleagues and let them know: there is a cause and a solution.

Option 1
"Most of us don't know what the flat surfaces we walk on every day are working against what our feet were built for. I didn't. I was introduced to Protalus Landing Gear and decided to give it a try. It bridged the gap for me and took away a lot of my ache, pain and discomfort. You might not know this might also be the solution for you."
Option 2
"From a colleague I learned about the flat ground we all walk on and the evolution of our feet are not made for that. I was introduced to Landing Gear — a total game changer for me. Improved each day to the point my feet and lower back does not hurt anymore. I am now a part of the mission to make every healthcare worker have the same opportunity and choice as I was given."
Option 3
"Over two million people bought Protalus Landing Gear. Different problems — feet, back, knees, fatigue. One thing in common: the flat ground we all live on. I am one of those two million. As one of many, I am on a mission to share this knowledge to as many of you as I can — because it helped me and many others, it may help you too."
Option 4
"I was skeptical about Landing Gear — but decided to give it a try because of a recommendation from my colleague. I am now convinced — and I want to make sure the knowledge about the flat ground we walk on and Landing Gear also gets to you. You make your own choice — but I want you to have the knowledge."
