Flat Feet Orthotics:

 

Ultimate Flat Feet Relief: Our therapeutic, custom orthotics are precision-engineered to stabilize fallen arches and eliminate instability common with overpronation. These are not simply generic insoles; each device is custom-made from a precise mold of your foot to provide crucial semi-rigid support that controls collapse and restores natural foot mechanics, and come with a Bilt labs warranty and guarantee.

Precision Correction 

The key to eliminating foot, ankle, and knee pain caused by flat feet is providing dynamic, rigid arch support to control excessive inward rolling. Our semi-rigid design offers robust hindfoot stabilization and prevents the midfoot from collapsing. By correcting overpronation, our custom orthotics enhance stability and relieve the widespread strain associated with fallen arches.

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.

What are Flat Feet?

The Pathomechanics of Overpronation

Total Arch Collapse

Flat Feet (Pes Planus) occur when the arches collapse, causing the entire sole to touch the floor. This leads to excessive pronation, where the feet roll inward too far.

Generic Foam Fails

Soft foam immediately bottoms out under body weight, offering zero structural support.

Internal Rotation

This inward rolling causes the lower leg (tibia) to rotate internally, putting massive strain on the ankles, knees, and lower back.

Frequently Asked Questions

Flat Feet Relief

Can custom orthotics and shoe inserts cure bunions?
Custom orthotics and shoe inserts cannot reverse a bunion deformity once the bone has shifted, as that is a structural change. However, custom insoles are highly effective at stopping the progression of the bunion and relieving pain by correcting the overpronation that causes the big toe joint to drift.
Will custom shoe inserts and orthotics fit in my shoes if I have a wide bunion?
Yes. One of the biggest issues with generic insoles is that they take up too much room in the toe box, crowding the bunion. Bilt Labs custom orthotics and shoe inserts are milled to be low-profile and typically stop just behind the metatarsal heads (3/4 length), leaving plenty of room for your toes and the bunion itself.
Do I need bunion surgery, or can custom orthotics and shoe inserts help?

Bunion surgery is often considered a last resort due to long recovery times. Most professionals recommend trying conservative treatment first. Custom shoe inserts and orthotics are the gold standard for conservative care because they address the root mechanical cause of the bunion, often providing enough foot pain relief to avoid or delay surgery.

Please note: You should always consult with a qualified healthcare professional or podiatrist to determine the best medical treatment plan for your specific condition.

Are custom orthotics better than bunion correctors or toe spacers?
Bunion correctors and toe spacers only address the symptom by temporarily pulling the toe straight, but they do not fix the underlying cause. Bilt Labs custom shoe inserts correct the poor foot mechanics (like flat feet or overpronation) that force the big toe joint out of alignment in the first place, providing long-term structural support and pain relief.
What are the best shoes to wear with custom orthotics for bunions?
The best shoes for bunions feature a wide, deep toe box made of flexible materials (like mesh or soft leather) that will not rub against the joint. When you pair a wide-toe shoe with Bilt Labs custom shoe inserts, you eliminate the mechanical pressure causing the bunion to grow, ensuring all-day comfort.

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 👌🏼

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!!

Great help!

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.

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.

I am very pleased with my orthotics

I am very pleased with my orthotics. They sent a mold and customized them for me after I submitted some information. The price is better than at other places I have checked and they are custom made. It took awhile to receive them, but it was worth it. I didn’t even have to leave my house for an appointment.
