If you were ever told you have flat feet, read this

Flat feet don't just hurt your feet. They're why your knees, hips and back do.

4 min read

Knees that ache after a long walk. Hips and back that start bothering you after a day on your feet. The lower back you've been putting down to age. If your arches have dropped, there's a good chance it all starts at the floor. And if you've been told a firm arch would hurt a flat foot, keep reading. That's covered.

Flat feet seen from behind, both ankles leaning inward

Sound familiar?

How it usually goes

See if this is yours.

  • Years agoSomeone said "you've got flat feet". It didn't hurt, so you ignored it.
  • Then the kneesThe inside of the knee, mostly, after a lot of walking. You blamed the sport, or the weight, or the years.
  • Then the hip and lower backA long day of walking or standing, and you wait for your hips and back to start bothering you.
  • NowYou look down and your ankles roll inward. A long walk means a day or two off your feet. Some days you walk like you're 90.
  • What you've been toldWear and tear. Lose weight. Take it easy. Maybe a replacement down the line.

If the pain has stopped your daily walks, keep reading. The joints that hurt are often not the joint with the problem.

What's actually happening

It isn't a knee problem. It's a foundation problem.

Think about one step. Your foot hits the ground first. If the arch is flat or has dropped, it can't hold the load, so the foot rolls inward. Everything above it has to adjust to a foundation that's leaning.

This is what happens, joint by joint:

  1. The arch dropsThe foot flattens and rolls in.
  2. The ankle leans inLook at your ankles from behind. If they tilt inward, this is you.
  3. The knee turns inThe shin follows the ankle. The load shifts to the inside of the knee. That's the ache after a long walk.
  4. The hip and back compensateOne hip tilts to level things up. The lower back takes the twist. That's the hips and back at the end of the day.

A few thousand steps a day, every day, for years. That's why it feels like age. But a leaning foundation doesn't get better with rest, and it isn't fixed at the knee. It's fixed at the floor, by holding the arch up so the chain never starts.

How a dropped arch sends strain up through the ankle, knee, hip and lower back

Why what you've tried didn't work

The arch supports you've tried go flat under a flat foot.

A flat foot puts more weight on the arch of the insole than any other foot. Soft ones fold on day one. Here's why each thing you've tried helped for a while, then didn't.

Knee sleeves, painkillers, rest · $

They quiet the knee. The foot keeps leaning.

Worth having on a bad day. But the knee isn't the problem, it's where the problem shows up. Tomorrow's steps load it the same way.

Helps for: the day.

"Supportive" shoes · $$

Cushioned, wide, comfortable. Still nothing under the arch.

A good shoe protects the foot from the ground. It doesn't stop the arch dropping inside it. The factory insole is flat padding.

Helps for: a few weeks, while the padding is fresh.

Drugstore arch supports · $

An arch shape in the box. Flat under your weight.

Soft padding shaped like an arch. Stand on it and it folds. A couple of weeks later, it stays folded. So the foot keeps rolling and the chain keeps running.

Helps for: about a week.

Custom orthotics · $$$$

Some worked. Some didn't. All cost a fortune.

People who've had them say the same things. They cost a fortune. You move one pair from shoe to shoe. When they wear out, you pay again. And some never helped at all.

Helps for: until they wear out. In one pair of shoes.

Flat feet, waiting for the hips and back to start

"I have flat feet, my feet hurt if I am doing a lot of walking or standing. I was doing a lot of walking and standing the other night and was honestly waiting for my hips and back to start bothering me and was surprised when they didn't. I've tried a lot of other products in the past. These actually work!"

The fix

Hold the foundation up, and the chain above it settles.

Custom orthotics work because the arch is firm. Held up, the foot stops rolling in, so the ankle, knee and hip stop compensating with every step. OrthoFlexx Max Arch Support Insoles do that one job, without the wait, the price or the podiatrist.

Arch Support that Doesn't Collapse.

  • Extra-firm arch base. Holds up to 330 lbs / 150 kg without flattening, so the foundation stays level all day.
  • A real arch, not a bump. Arch elevation 1.38" / 3.5 cm, where a dropped arch actually needs it.
  • Deep heel cup. Keeps the heel centered, so the ankle stops leaning in while you wear them.
  • Fits the shoes you already own. Full length, trim-to-fit. Walking shoes, sneakers, everyday shoes.
  • Soft on top, firm underneath. Support, not a plank.

Knee pain for a few years

74, ankle degeneration, knee problems

"I have experienced ankle degeneration due to an old injury that led to knee problems. These have really helped! I'm 74 years old, 6'2" tall, and weigh 200 lbs, so I needed something that had the capability of holding up and not compressing."

Straight answer

What the first weeks actually feel like

Firm support under a flat foot is a change. If you've never worn it, here's what to expect, and it isn't too late at any age.

Days 1 to 7

Your arch will notice it. That's the support working, not a wrong fit. Start with 2 to 4 hours a day, around the house is fine. If it's too much for a very flat foot, we'll swap you to the lower arch, free.

Weeks 2 to 3

Feet and ankles first. Then people start noticing their knees, hips and back at the end of the day.

Weeks 4 to 6

The knee, hip and back changes people report take the longest, because those joints have been compensating for years. If nothing has changed by day 30, refund.

Knees, hips and back

"The arch support wasn't moving or giving in under my weight but felt firm and secure. My left foot had taken longer to adjust. Now, I can feel the aligning of knees, hips and back. Knee pain has lessened."
