IAMBIC engineers precision-fit footwear built to the millimeter through advanced smartphone scanning, AI, and biomechanics. Designed in New York City and crafted in Portugal, your foundation begins with the MODEL T. From there, the Precision Fit Program evolves with you as each new pair refines comfort, posture support, and all-day balance.
Recognized as a TIME Best Invention and backed by the U.S. National Science Foundation.
Why footwear should evolve
Your body adapts with movement, work, and time, but traditional sizing does not. The Precision Fit Program keeps pace through AI, biomechanics, and wear data, allowing comfort and alignment to improve pair after pair.
“Two people can share a size. Their needs rarely match. Precision fit treats your body as the blueprint.”

How the Precision Fit Program works
The journey starts with your first pair — your MODEL T. After a 3-image scan and comfort profile, each new pair evolves through Sole Print™ wear analysis and feedback. Learn more on the Precision Fit Program page.

1 — Your fit perfected
Your digital last stays on file. Adjustments such as additional arch support or toe room are integrated into future pairs.
2 — Sole Print™ wear analysis
Sole Print™ maps how your shoes meet the ground. Photos of your outsole reveal pressure and balance patterns, guiding updates to cushioning and structure.
3 — Smarter with every pair
Members can share comfort check-ins and step data alongside Sole Print™ photos. These signals shape annual refinements for balance, posture, and long-day comfort.
Why it matters
Fit determines how force travels through your kinetic chain. Even small misalignments can create fatigue or posture shifts that affect focus. By transforming footwear into an adaptive system, IAMBIC helps you stay balanced through long days, airport walks, and city commutes.

The most interesting thing about them being crafted just for me is how well they fit. And I hadnever even noticed that my shoes didn't fit right. My other shoes don't hurt me - they just slosharound. With these, the heels actually stay on the whole time and it fits snugly yet stillcomfortably. And I'd never experienced that before. They just stay comfortable all day.
As a runner, as an athlete, just knowing that I'm doing a good service to my body is incredible.It’s the reason that I love my IAMBIC shoes. It's that precision that makes me feel safe to walkdown the street, get on the subway, do my commute, bring my kids to school, and not feelconcerned that I'm doing it in a shoe that doesn't fit right or that doesn't feel good.
The thing that I was surprised by the most with the precision fit is that any pressure points thatI had been feeling with the shoes that I previously came in wearing were completely gone. I waswearing a shoe that wasn't too tight. It wasn't too loose. The sole fit just right. Total comfort.That's the best way to put it.
So I suffer from chronic foot pain and I believe that a lot of that has to do with wearing shoesthat actually don't fit. Whenever I wear my IAMBICs, I've noticed that I have felt less pain,which is really incredible. And they're just so comfortable. I'm not worried about the back of my heel popping out or my ankles not having enough support. Also, they're just so stylish andevery timeI wear them out in the street, I always get compliments, which never happens to me.
A shoe that may feel comfortable for a half hour walk is not a shoe that always feels comfortablefor a three and a half hour walk. So what I like about IAMBIC is, even though the snug fit isthere and it feels comfortable, it also feels substantial enough that I can walk a lot withoutgetting any discomfort. That's just something that's especially important to me and I think theshoe has really delivered that.
The first moment that I tried on my IAMBIC shoes, I noticed a difference. I have small feet. So whenever I try on shoes, I usually expect them to not fit. If they do fit, there's usually some sort of discomfort, whether that's in the toe box or too much space or at the heel. So knowing that this shoe was tailored to my foot was really meaningful. It's rare that you find a shoe like IAMBIC that truly is comfortable, but also hits the markers of style versatility.
I think we're all placed on this earth as unique individuals. None of us are really off the rack in terms of sizing. So for me to have that experience of having something made specifically for me that fit perfectly was something that was a little bit mind blowing. And once I got the shoes, I tried them on, they looked great, they felt great. And honestly, they fit like a glove.
