Supination Orthotics:

 

Ultimate Supination Relief: Our therapeutic, custom orthotics are precision-engineered to compensate for the extreme rigidity and poor shock absorption common with supination. These are not simply generic insoles; each device is custom-made from a precise mold of your foot to provide crucial cushioning and flexibility, improving force distribution and preventing excessive ankle or lateral knee stress, and come with a Bilt labs warranty and guarantee.

Precision Correction 

The key to treating supination is providing a balance of motion control and superior cushioning where the foot strikes the ground (the lateral edge). Our custom design includes features to help the rigid foot absorb impact more effectively and encourages a gentle, healthy degree of pronation. This greatly reduces the stress that travels up the leg, helping alleviate pain in the ankles, shins, and knees.

Unparalleled Performance

Built from your unique foot mold and detailed health information, we guarantee a truly precise fit that mass-produced supports cannot match. Choosing Bilt Labs is choosing a durable, evidence-based therapy that offers reliable support and improves gait alignment for long-term comfort and mobility. Backed by our lifetime shell warranty.

Understanding The Condition

What is Supination?

The Pathomechanics of Outward Rolling

Supination (also known as underpronation) occurs when the foot rolls outward excessively as you step. This puts immense pressure on the lateral (outer) edge of the foot and the smaller toes.

Because the foot doesn't roll inward enough to absorb shock naturally, impact forces are transmitted directly up the leg. This rigid locking of the foot often leads to ankle instability, stress fractures, and knee pain.

Common Symptoms:

  • Frequent ankle sprains or feeling of instability.
  • Pain on the outer edge of the foot or heel.
  • Shin splints and IT Band Syndrome (outer knee pain).
  • Calluses on the outer edge of the foot.

Fast Facts

  • Prevalence: Less common than flat feet but often more painful.
  • Risk: High arches (Cavus foot) are the #1 cause.
  • Correction: Lateral wedging pushes the foot back to neutral.

Background

Treating the Root Cause of Supination

The Problem

Outward Rolling

Generic insoles usually focus on arch support for flat feet. They often make supination worse by pushing the foot even further outward. They lack the specific lateral wedging needed to stabilize a high arch.

Result: Continued ankle instability and shock impact.
The Bilt Solution

Lateral Stability

Bilt Labs custom orthotics are designed with a lateral post (wedge) that sits under the outside of the heel. This gently tilts your foot back inward to a neutral position, preventing the outward roll.

Frequently Asked Questions

Supination Relief

Can custom orthotics and shoe inserts fix supination?
Yes. Custom insoles and orthotics are one of the few effective ways to manage supination. By using a lateral post or wedge on the outside of the foot, the custom insert mechanically tilts the foot back towards a neutral position, preventing the outward roll that strains your ankles and knees.
Do I need firm or soft support for supination?
Supinators often have rigid high arches that don't absorb shock well. Therefore, you need a balance: firm structural support on the outside to stop the rolling, combined with shock-absorbing materials to cushion impact. Generic soft insoles won't provide the necessary lateral stability. Bilt Labs custom shoe inserts provide this precise balance.
Will custom shoe inserts for supination help prevent ankle sprains?
Yes. Chronic ankle sprains are a common symptom of supination because the foot is constantly teetering on its outside edge. By widening the base of support and stabilizing the heel with a custom shoe insert, we significantly reduce the risk of rolling your ankle.
What is the difference between supination and overpronation?
Supination (or underpronation) occurs when your body weight rolls onto the outer edges of your feet as you walk. Overpronation is the exact opposite, where the foot rolls inward and the arch collapses. Custom orthotics are essential for both because they are specifically milled to address your unique foot mechanics, providing lateral support for supinators and medial support for overpronators.
What are the best shoes to wear with custom shoe inserts for supination?
The best shoes for supination are neutral, cushioned running or walking shoes with a flexible midsole. Because supinators naturally lack shock absorption, a well-cushioned shoe paired with the structural lateral support of a Bilt Labs custom orthotic creates the ideal environment to protect your joints and prevent outward rolling.

Product & Service

Are Bilt Labs shoe inserts and insoles truly medical-grade?
Yes. These are custom-fabricated from a physical mold of your foot using the same medical-grade polymers and EVA foams supplied to podiatry clinics. Each pair is reviewed for clinical accuracy to function as a true custom orthotic rather than a generic foam insole.
Do you take insurance or FSA/HSA for custom insoles?
We are approved to accept FSA/HSA cards directly at checkout for all custom orthotics and inserts. We do not bill insurance directly but provide a detailed invoice for reimbursement.
What is the warranty on custom shoe inserts?
Bilt Labs provides a lifetime warranty on the orthotic shell against breaking. We also offer a 6-month money-back guarantee with free adjustments.
How long does it take to receive my custom orthotics?
Once you place your order, we ship out your foot mold impression kit within 1-2 business days. After we receive your molds back at our lab, we design, build, and ship your custom insoles within 21 business days.
How long will my custom orthotics last?
Bilt Labs custom shoe inserts typically last a minimum of 2-3 years. The rigid shell itself often lasts longer (and has a lifetime warranty against breaking), but the soft top covers may show wear and can be refurbished.
What is your return/refund policy?
We offer a full 6-month trial period. If you are not fully happy with your custom insoles by that time, you can return them for a full refund. We also offer 2 free adjustments during this period to ensure the fit is perfect.
Where are my orthotics made?
Your new custom shoe inserts are made in the United States. We are located in the Houston, Texas area. All fabrications, designs, and finishing are performed by experts right here in our Houston lab.

Better Than $500 “Medical” Orthotics

I’m a mailman with extremely flat feet. After going through 3 pairs of custom orthotics from doctor’s offices - to the tune of $500 EACH - none of which ever truly felt comfortable, I needed to find a better solution.

My wife had tried Bilt Labs and was over the dang moon about her orthotics. I tried their 2-pair deal and got the exact same custom food casting mold I’d used in the doctor’s office. That’s when I realized, the doctor’s, tho good at their jobs, were just middlemen when it came to the orthotics.

I cut out the middlemen and got a quicker turnaround time and orthotics that actually feel good on my feet! The attached photo is just a little longer than 6 months into wearing them and taken after 10 hours of trudging through snow & ice delivering mail and heavy packages. They still look in great shape (the front big toe area of the right insole is starting to peel just a tiny bit but I’m honestly surprised this hasn’t happened sooner, with how much abuse these things go through).

Instant relief

My wife gifted me the foot mold impression when my feet started hurting. I do have high arches, therefore I had to purchase work shoes/boots that accommodate my custom orthotics. It has been a great relief and pleasure to my high arches during my 10-14 hour work shifts!
Definitely recommend 👌🏼

I really appreciate the precision and the excellent customer service of Bilt labs orthotics. I was very hopeful it would solve my foot pain. However, mine turns out to be more structural and bone spurs and so they did not help. I do feel like if I didn't have the bone spurs, they would be excellent. Laura was the customer service representative that made it easy to get a refund.

Simply the Best Inserts by Far!!!

After trying numerous over the counter varieties and then going to a podiatrist for custom made (cost >$450 and had to go back twice; they still didn’t work), I tried Bilt Labs. The staff is exceptional and caring!!!

When they arrived and first used them my feet felt fantastic instantly. I went from having severe pain just walking short distances to immediately being able to run around in them!! Prior to receiving these I had given up being able to play tennis for nearly 18 months because I could only play a few games before I had to quit playing.

These inserts were live changing for me. I could now play competitively for an hour. However, after an hour of playing I started to notice some minor discomfort in my right foot. At first I ignored it. Then I decided to call BILT LABS.

The associate I spoke with asked me several questions about where the pain was on my foot and told me they would make a minor adjustment to my insole. They sent me a new right insole. It worked perfectly and I was able to play for hours without any discomfort. When I called Bilt back and told them, they sent me replacements for the right insert for the other pairs I had purchased.

Sine then I have purchased other pairs so I don’t have to keep moving them from shoe to shoe.

Thus far I have been using them for about two years. They are still working great.

I am very happy with Bilt Labs and Highly Recommend their product!!

HONEST Company!

I am SO impressed with Bilt labs. I have a rare decease called Charcot foot where, Bones break down in the feet and can come through your feet. Also, I’ve suffered with neuropathy for 28 Years. My condition is so bad the Bil labs contacted me to tell me the orthotics would not be a good match for me. They could have cared lesss and sent them to me. But, they were honest and called me personally and explained why they would be more damage then good and I needed to stick with my RX orthotics here in my city. Honesty is something that many people lack. I’m so impressed. They gave me a complete refund. They didn’t charge me for the mold kit. If you’re thinking about using them think no more!

Customer Service/Product

I run a company and the woman in customer service was outstanding! She was knowledgeable, helpful and beyond what I had expected. The insoles are the best I’ve ever had. I played basketball overseas and I can tell you I tried dozens of high-quality orthotics. These by far help my feet pain more than any other brand that I have tried in the past. Are they expensive yes, are they worth it yes. My experience with this company is a perfect 10.

Excellent

After buying “custom insoles” online, seeing a Podiatrist and exploring The GFS retail insoles, I came across Bilt Labs. The ordering process is easy, you step into a mold with both feet and give them some information. Days later, after lots of updates, you receive your insoles. They are an exact fit to your feet, not a one size fits most. No microwaves, ovens or changing insoles throughout the day.
The feeling of an exact fit is comforting! You should try Bilt Labs.

Great compliment

I previously wrote a review on how much I liked my insoles and how nice it was to deal with this company but because of this I decided to write an additional one. I recently had to see my physician who specializes in foot and ankle problems. I was wearing my orthotics and after looking at them he remarked that they were extremely well made. I thought I would pass that along.

New life for a 75yr old!

Due to the pain in my feet I had basically become inactive. For 5 years I went doctors, did rehab exercises, read everything I could find about foot pain. Started using shoe inserts, adding pads to different positions on the inserts. It did make a difference but far from completely fixing the pain. Found Biltlabs, researched them and gave it a shot. Very Happy! No pain! Walked over 18 miles while in Chicago over 3-days. I couldn’t walk over 3 blocks without one foot or the other giving out. If everyone gets the results I got… incredible! Life changing! Highly recommend!!!
