Every IAMBIC pair begins with a 3D scan that captures more than twenty biometric variables per foot. The Fit Engine translates that data into a digital last measured in millimeters, creating footwear designed to move in sync with you.

We spoke with David about comfort, substance, and why AI-tailored fit reset his standards. He wears the MODEL T professional sneaker.
AI-tailored luxury sneakers that travel well and look sharp
David wanted one pair for long walks and meetings on the same trip. With a made-to-fit pair, comfort held over distance and the look worked with a suit or casual fit. See the MODEL T.
- Lower fatigue: Comfort that lasts through long days.
- Posture support: Balanced feel across miles.
- Versatility: Refined enough for suits, relaxed enough for travel.
- Consistency: Reorders keep your personalized fit dialed in.
How personalization raises the bar for comfort and value
Mass sizing is a compromise. Shape and volume vary by person and between feet, which is why hotspots and slip happen.
The IAMBIC method pairs a three-image smartphone scan with a short comfort survey to model more than 20 biometric variables. A biomechanical engineer reviews your fit plan and creates a digital last made just for you. Over time, Sole Print wear analysis and a learning loop guide each next pair.

Q&A with David
Can you describe the experience of getting a bespoke pair of shoes from IAMBIC tailored uniquely to you?
This was my first pair of bespoke shoes and I really enjoyed it. I like the aesthetic and style, the trim around the edge of the sole, and the sturdiness of the shoe. It feels substantial. The fit works perfectly regardless of socks or conditions, and the versatility means I can wear them with a suit or in a casual outfit.
How did it feel wearing a true one-of-one pair of shoes crafted just for you?
I was a sneakerhead back in the day with a pretty extensive collection, from Converse to designer brands. This was the first time I had something made exactly for my feet. The difference shows in the experience. It is tailored to the idiosyncratic shape and arch of my foot. I do not even have a bespoke suit, so I am starting from the feet up.
What does owning an edition-of-one pair of shoes mean to your style?
I like that the MODEL T blends the look of a dress shoe and a sneaker. Mine have green trim, but I can imagine having another pair with red. It feels special to have something functional that also reflects my identity. Walking long hours in New York is easy now. No soreness or irritation, just comfort.
How do you feel about the look and style of the shoes?
The design is a real selling point. I travel light and needed one pair for workouts, meetings, and dinners. I chose my IAMBICs because they worked everywhere. They were stylish enough for Europe and durable enough for walking all day. I have never had that balance before.
How did the smartphone-based scan affect the fit you feel now?
The shoes are substantial and supportive. I need a shoe with structure for long walks, and this provides that. Even though the fit is snug, it feels secure, balanced, and never heavy. I can walk for hours comfortably, which is a major upgrade.
How does IAMBIC’s technology set it apart from other shoe brands?
Technology has transformed so many industries, from skincare to food, and footwear is no different. IAMBIC uses data and biomechanics to improve one of the most important parts of daily life—how your body moves. The precision and personalization feel like the future of footwear.
What excites you most about your shoes learning from you through Sole Print?
I think it is amazing that the shoes evolve with my movement. Like Netflix or Spotify, they learn from use and adjust over time. It is exciting to have a physical product that improves with wear and provides more value the longer I own it.
Can you describe the moment you first put them on?
They felt snug and natural, like a substantial slipper that fits perfectly. The process was simple, no need to test different sizes. It just worked immediately, which was impressive.
How has precision fit changed your view on footwear?
It has made me rethink my collection and the price I am willing to pay for non-custom shoes. With one black and one white pair of IAMBICs, I can replace several other shoes. It redefines value, comfort, and performance in my wardrobe.

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 shoes that 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 and every time I 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.
