Who it's for

One tool.
Three types of users.

Whether you're printing your first pair or running a clinical case load — the same parametric engine, the right amount of control.

/ Everyday

Insoles for the shoes you actually wear every day.

Long commutes, standing desks, casual walks — no special training needed. Answer a few simple questions and get a comfortable, custom-fit insole printed in flexible TPU, ready to drop into any shoe.

/ Clinicians

Full orthotic vocabulary. No CAD required.

Arch height, heel-cup depth, varus/valgus posting, medial skive, flange width — all exposed as direct numeric inputs. Go from intake to downloadable STL in under 10 minutes per patient.

/ Labs & Studios

High-volume design with versioned history.

Studio Pack includes 6+ month credit validity, full parameter access, saved design history, and dashboard. Built for steady case volume without per-seat CAD licensing.

How it works

A smart guided system,
not a CAD tool.

You describe the insole in natural language. The system infers the right parameters — arch height, heel cup, skive, posting, lattice density, material — and generates a print-ready STL. If you know what you want, override any value. If you don't, just print.

Overview

A parametric workshop for
your feet.

Most insole tools are either rigid templates or require a full 3D scan rig. Ergono3D lives in between: a web app that captures the measurements that actually matter, then computes a print-ready STL, lattice-reinforced geometry tuned to your biomechanical goals.

/ 01 · Clinical

Heel-cup depth, skives, posting, flanges.

All of the parameters a podiatrist would write on a prescription form — exposed as direct numeric inputs, not buried in a CAD tool.

/ 02 · Athletic

Tuned for sub-10s sprinters. And everyone else.

Insole profiles co-designed with biomechanists who work with elite athletes. Stiffness zones, rocker geometry, forefoot plate geometry included.

/ 03 · Printable

TPU 85A / 90A / 95A out of the box.

Every STL is clean, shell-stable, and pre-validated for common slicers. No mesh cleanup. No support nightmares.

End to end

Print. Wear. Refine.

Export a custom insole STL from Ergono3D, print it on any TPU-capable FDM printer, then wear-test and refine the parameters until the fit feels right.

In the wild

What comes
off the bed.

Real pairs printed with Ergono3D STL exports and default TPU slicer profiles. Same parametric generator, different materials, colour blends, and lattice densities.

Workflow

Four steps. Under ten minutes.

No calipers. No CAD suite. Answer a few guided questions and walk away with a print-ready STL — then refine as you go.

Profile

Answer guided questions about your daily use, arch type, pain zones, activities, and shoe type. No measurements needed.

Generate

The system computes a lattice-reinforced insole geometry tuned to your inputs — typically under 90 seconds. Tweak any parameter manually if you want.

Print

Download the STL, slice, and print on any TPU-capable FDM. Slicer profiles included for Bambu, Prusa, and Ultimaker.

Iterate

Wear-test and refine. Every generation is versioned — adjust a single parameter, re-generate, and compare against the previous run. No starting over.

Control surface

Every insole parameter, agent-guided.

Ergono3D starts from an expert-designed base insole shell, then layers adjustable controls on top: heel cups, skives, posting, flanges, arch geometry, and met pads. Our Agent helps individuals and clinics quickly find reasonable parameters, then iteratively update them as fit and comfort evolve.
