Introducing Interplay™

Your Complete Workflow.
Play, refine, make. Print and repeat. Built-in validation means you create production-ready designs without barriers, just flow.
01
Play.
Upload sketches, describe ideas, or start from inspiration. Begin wherever creativity takes you.
02
Refine.
Iterate fearlessly. Automatic validation catches manufacturing issues as you work, so you stay in flow.
03
Make.
Export STL files or presentation images. Print with Zellerfeld, any 3D service, or share your designs.
From Sketch to 3D
Upload a sketch and generate 3D models. Iterate by adjusting parameters and regenerating—no CAD skills required.
Perfect Fit, Automatically
Your designs auto-fit to shoe lasts for accurate proportions and wearable geometry.
Manufacture-Ready Files
Export STL files ready for 3D printing or production. Print with Zellerfeld, use any 3D service, or share presentation images with collaborators.
“HILOS solves product creation problems visually, verbally, and conceptually. The vibe is always ‘Let’s make this better, together.’”
Miranda Morrison, VP of Design, Steve Madden
“I’d bet my bonus this is going to change everything.”
Ken Ratterree, KEEN

Close the gap between concept and reality with the only software built on industry footwear knowledge.
Solutions

Built For Designers

Design and manufacture footwear with no CAD, no minimums, and no gatekeepers.
  1. Manufacture-Ready
    Instant validation ensures your designs can actually be made. What you see on screen works in production.
  2. Privacy First
    Privacy isn't a premium feature—it's the foundation. We don't train foundation models on your IP. We don't share with third parties. We don't build shadow profiles.
  3. Export Anywhere
    Design packs, STL files for 3D printing, or export for Zellerfeld. Your designs work with any manufacturer—no platform lock-in.
Design shoes in hours, not months.
Interplay™ handles the technical complexity—from sketch to 3D model to production-ready files. Start however you want and manufacture without barriers.
