The most interesting thing about them being crafted just for me is how well they fit. And I had never even noticed that my shoes didn't fit right. My other shoes don't hurt me - they just slosh around. With these, the heels actually stay on the whole time and it fits snugly yet still comfortably. 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 walk down the street, get on the subway, do my commute, bring my kids to school, and not feel concerned 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 that I had been feeling with the shoes that I previously came in wearing were completely gone. I was wearing 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 comfortable for a three and a half hour walk. So what I like about IAMBIC is, even though the snug fit is there and it feels comfortable, it also feels substantial enough that I can walk a lot without getting any discomfort. That's just something that's especially important to me and I think the shoe 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.
Text: 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.
