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.

  • Everyday (Memory Foam): Ideal for maximum cushion and all-day standing or walking.
  • Active (High Rebound): Engineered for high-performance use, providing superior shock absorption and energy return for fitness and long work shifts.

What is Supination?

The Pathomechanics of Outward Rolling

Excessive 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.

Generic Foam Fails

Store-bought insoles cannot control severe angles. They just cushion the problem without correcting it.

Lack of Shock Absorption

Because the foot doesn't roll inward enough to absorb shock naturally, impact forces are transmitted directly up the leg.

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 semi-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 custom shoe inserts are manufactured in our central USA-based facility. All fabrication is performed by experts right here in the USA.

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 👌🏼

Absolutely the best insoles I ever purchased

I cannot begin to express how grateful I am for finding this company. I have been wearing my new insoles for 3 weeks now, and I am so satisfied that I just ordered a second pair so I don't have to keep switching them out with other sneakers. I also recommended them to a friend who also ordered some and is totally satisfied and is ordering another pair. The satisfaction is such that this is snowballing and that friend now has his brother ordering. Fantastic product and highly recommend it!!

I have become a huge fan of Bilt insoles

I have become a huge fan of Bilt insoles. I must have bought and tossed out at least a dozen off-the-shelf products and some felt fine at first but then after a longer hike, pain would develop, usually along the outside edge of one foot. I then went to a podiatrist and spent tons of money on orthotics which helped but were expensive and made me feel like i was walking on a tennis ball. Then i found Bilt. I can walk forever now and have no pain. There are times after a long hike that I come home and leave my shoes on because they feel like my feet are getting a hug with each step, truly. Perfectly molded for each foot's needs rather than trying to use a standard. I doubt many people's feet are "standard." So I will be placing an order for my 3rd pair since my second pair arrived recently and the test proved to me that they are as good/same as my first pair. This from a 74-year-old who hikes 7+ mile hikes two or three times a week and recently completed my second Camino de Santiago in Spain, using these insoles. Huge fan.

I’ve got insoles from my podiatrist and they were

I’ve got insoles from my podiatrist and they were great. Love my doctor but I didn’t have to go back and get new ones. Bilt Labs does the same procedure my doctor did for half the cost and it all comes to my house. This will be my second pair and love them.

Have worn insoles for years after Planter

Have worn insoles for years after a bout of Plantar in my left foot. After Shockwave Therapy I started using medical inserts and now this Bilt Labs service.

Excellent product that is better than any medical grade. They remind you to reorder on a regular basis as they do last a long time but are in some pretty tough conditions!!

Just leaving a review to say how helpful the team has been. I had an issue with the mold kit that arrived and after emailing about it, Laura M. Immediately sent me a replacement mold so that I would have the most ideal experience. Looking forward to using my custom orthotics when they get made!

Great comfort. Almost instant pain reliëf.

The insoles were delivered as per schedule. They fit perfectly, are finished with an eye for comfort and have helpers me relief pain, within weeks of using them. You do need to allow for a few days of getting used to them in whichever show you decide to install them.

Excellent Quality, Great Product

I was searching for insoles for my feet for several years. I tried all of the over the counter, less expensive ones. I must have bought 50 different pairs. Nothing helped my feet. I finally got a job that offered FSA benefits, and I was browsing online for places that accepted FSA. Bilt came up and I thought to myself that it couldn't hurt to try them out, since all the others ended up in failure and a ton of foot pain. Yes, they are expensive. Buy multiples. All of your shoes need these. Seriously. Don't try to be that guy who moves his insoles from shoe to shoe. It's not worth it. Just buy more. I ordered 2 everyday and 2 active, the first time. That got me through the first year. That was last year. This year, I got new shoes, and needed new insoles again, since you really don't want to use insoles for longer than a year, anyway. So in January, again, I ordered two more pairs of active insoles.

I work in a demanding job, on my feet and moving, for 13 hours a day. Out of 14 days, I work 10 days. So I'm tough on my shoes and I need insoles that can handle that. The active insoles live up to their expectations and then some.

The foam kit to make the insoles is a little weird to use, but it's honestly worth every icky feeling to get insoles that are this great.

And just in case you care, I'm now ordering my third set, since I broke my newer shoes and need more active insoles. I'm a customer for life - and I can be, since they keep the mold for future use.

Thank you Bilt Labs for curing my foot pain. The insoles work wonders. I have come back for reorders on both the Everyday - Memory Foam and Active - High Rebound even thoug it's been only about 6 months since I first placed orders as a new patient.I wish i had known you earlier! Much appreciate!

These insoles have helped my pain so.much. I have a bump that was developing on my Achilles and it would hurt so bad during the day I would be limping about halfway through. With these my feet have found comfort that lasts.

I tried different inserts from different vendors,

I tried different inserts from different vendors, but not custom. My doctor recommended custom inserts that would have costed $700. Then I found Bilt labs on a google search and the reviews were great. All for less than half of what the doctor recommended. Let me tell you, they work. It’s been about 3 months and I’m already ordering a second pair. The process was well described and everything happened as planned. My plantar fasciitis was acute. It took about 4 weeks for the pain to go away and about 8 weeks to feel less tight. No more pain first thing in the morning. But you have to keep wearing the inserts. In the house I wear something with support, like Cushionaire, and outside sneakers with the Bilt labs inserts.
