Beyond 'Fit': Midsoles Engineered for Your Biomechanics
Forget one-size-fits-all foam. We've replaced the traditional, imprecise method of mass-produced midsoles with a revolutionary 3D structural mechanics solution. Each FIZO midsole is a dynamic system, 3D-printed to respond not just to your size, but to how you move. It's not a shoe that fits. It's a shoe engineered for you.
The SoleFlow™ Lattice: A Revolution in Cushioning
Our midsoles are not solid blocks. They are a matrix of thousands of precisely designed 3D-printed micro-units. This SoleFlow™ Lattice allows us to fine-tune density across the entire footbed, creating a structural solution for ultimate stability and knee protection at a fraction of the weight.
Weight-Calibrated Performance: A World First
Traditional running shoes are built for an "average" weight. If you're lighter, they feel stiff; if you're heavier, they collapse and fail to support you. FIZO is the world's first shoe to calibrate midsole density directly to your body weight, ensuring perfect cushioning and support on every single run.
Targeted Support: Correcting Imbalances Before They Cause Pain
Many runners experience overpronation, leading to knee stress. Our system addresses this directly by engineering a denser lattice on the inner side of the shoe. This provides targeted structural support, gently guiding your foot into a neutral alignment and significantly reducing injury risk.
True Personalization: Down to the Millimeter
Beyond weight, we build a shoe that is uniquely yours, because no two feet are the same. We offer true independent customization for your left and right foot.
Length & Width
A precision fit for your exact foot shape.
Independent Left/Right Design
Two feet, two completely custom-built shoes.
SoleFlow Simulator
Adjust size, width, arch height, and weight to see how lattice density adapts in real-time. Each cell represents a 3D-printed support structure that responds to your foot's pressure distribution.

Why FIZO Exists
We're runners who know the pain of ill-fitting shoes—especially our lead designer Koko, a 100kg (220lb) daily runner who always says: 'The running shoe industry has failed athletes with real bodies.'
With 13 years in footwear development and a brand that achieved $70 million in annual sales, we've seen the industry's biggest lie: the myth of the "standard foot." When Koko's ankles kept buckling under inadequate support, we decided to rewrite the rules.
FIZO isn't just footwear - it's our apology.
To wide feet. To high arches. To every runner who's ever been told their feet are the problem. We use 3D printing to craft shoes for every foot left behind: heavier runners, flat arches, asymmetrical feet, and more.
"Our unique feet aren't flaws - they're the blueprint for better design." - Koko
