How to Measure Your Foot
Stel-I Aries embodies the pioneering energy of the ram. Printed from zellerFOAM® TPU by Zellerfeld, each pair is made to order for your unique foot shape — no sizes, no compromises.
How It Works
Experience footwear engineered specifically for your feet
Order Your Pair
Purchase your Stel-I Aries. Each pair is made-to-order just for you.
Scan Your Feet
Use your phone camera — no app needed. Our browser-based scan, powered by Zellerfeld, takes under two minutes using just a sheet of paper for scale. Millimeter-level precision, captured from home.
Precision Manufactured
Printed in Austin, TX and Hamburg, Germany by Zellerfeld using zellerFOAM® TPU. Single-piece additive construction — no glue, no stitching, no weak points.
Delivered to You
Your made-to-order pair ships within 3–4 weeks. Free shipping to the US and EU. Tracking provided once dispatched.
Built for How Feet Actually Work
Most footwear ignores a fundamental truth: no two feet are the same — not even your own. Zellerfeld's scanning technology fixes that.
Asymmetry, Solved
Around 70% of people have feet of slightly different lengths. Traditional sizing forces a compromise — you size up for one foot and the other floats. Our scan captures both feet independently and prints each to its own exact length. No more choosing the lesser of two bad fits.
Powered by Zellerfeld.
Room to Breathe
Standard shoes taper at the toe box, compressing toes into an unnatural position over time. The Stel-I is printed to your exact forefoot width — so your toes splay naturally as they were designed to. No pinching, no pressure points, no break-in period.
Sub-5mm Precision
Our browser-based scan achieves millimeter-level accuracy using only your phone camera and a sheet of paper. No app to install, no appointment required — precise measurements captured in under two minutes, directly from home.
Powered by Zellerfeld.

Aries represents the raw energy of life itself — pure, pioneering, unstoppable. Those born under this fire sign carry an unshakeable confidence and an instinct to move first.

Everything You Need to Know
No Traditional Sizing Needed
Our foot scanning technology captures over 20 data points per foot — length, width, and volume — to create a fit that traditional sizes cannot achieve.
100% recyclable thermoplastic polyurethane — the same advanced material used throughout the entire shoe. Zellerfeld's proprietary formulation for a soft, sock-like feel.
