Digital orthotics
What custom 3D orthotic insoles are and how they're designed
Published: 2026-04-10 · 6 min read
Custom 3D orthotic insoles are devices manufactured to the patient's foot from a digital scan. Unlike standard insoles, their geometry is computed with real patient data: arch, loading zones, asymmetries and specific clinical needs.
How they're designed
The workflow starts with a foot scan — using the ELISA iPhone app or any external 3D scanner. The system builds a 3D representation of the foot and, on top of it, generates the parametric insole design.
- Capture: iPhone app or external scanner (STL)
- Geometry validation
- Parametric generation with lattice structure
- 3D preview and clinical adjustments
- STL export or print-on-demand
Why lattice structure matters
TPMS lattice structure lets stiffness vary across the foot, tunes mechanical behavior to usage (medical, sports, comfort) and reduces weight while keeping durability.
