TL;DR
There is no single price for custom orthotic insoles. Clinics may bundle or separately charge for the assessment, taking measurements or a cast, design, fabrication, delivery, follow-up visits and adjustments, so two quotes are only comparable when they cover the same scope. Ergono3D covers the design and the STL file — not the clinical assessment, the printing or the follow-up.
Key takeaways
- Custom means fitted to one foot. It is designed from that foot's real characteristics, not picked from a size catalogue like a pre-made insole.
- Design works parameter by parameter. Arch height and length, heel cup depth, varus or valgus posting and skives define how the insole supports and guides the foot.
- TPU and 3D printing are one way to make them. A digital workflow can turn parameters into an STL and produce it on a compatible machine, but it does not replace a professional assessment when one is needed.
- Cost depends on what the service includes. Assessment, design, fabrication, delivery, follow-up and adjustments can be quoted together or separately.
- They can be produced in the clinic. With Ergono3D, guided design and STL export let a clinic generate the geometry and reprint after wear feedback.
- It is a design tool, not a clinical one. Ergono3D does not diagnose or treat; assessment and clinical judgement belong to the health professional.
Custom insoles can follow a cast-and-lab process or a digital workflow. In the digital one, foot data become parameters, the geometry is checked on screen and an STL is exported for fabrication. Below we separate assessment, design, production and follow-up so prices can be compared on the same scope.
What is a custom orthotic insole?
A custom (or personalised) orthotic insole is a foot support designed around the specific characteristics of one foot: its arch height, heel shape, pressure distribution and the way it moves when walking. It differs from a pre-made insole in one essential point: a pre-made insole is built for an "average foot" and chosen by category — high, medium or low arch — while a custom one starts from the data of that particular foot.
Pre-made categories are usually limited to size, width or an approximate arch. A custom insole can adapt more variables and treat the two feet differently, but that ability alone does not guarantee a clinical result. The choice depends on the case, the footwear, the fabrication and, when there are symptoms or risk factors, a professional assessment. We cover this in custom insoles vs. pre-made inserts.
How custom orthotic insoles are designed: arch, heel cup, posting and skive
In practice, designing a custom insole means tuning a set of interdependent parameters from the foot data:
- Arch height and length: where the geometry creates contact, and how much.
- Heel cup: depth and contact around the rearfoot.
- Posting and skive: change rearfoot angles and geometry; their clinical use should be decided by a professional.
- Medial or lateral flange: adds geometric containment on the inner or outer edge.
A parametric approach adjusts these values together for the case at hand instead of starting from a fixed template — and it needs no CAD or scanner: guided inputs generate the geometry, which is reviewed before fabrication. Each parameter is explained in insole design parameters.
Materials and fabrication: TPU and 3D printing
TPU 3D printing is one way to make custom insoles. TPU is sold in nominal hardnesses such as 85A, 90A or 95A, but the final feel also depends on the brand, geometry, walls, infill and print settings. One possible workflow: foot data → parametric design → review → STL → fabrication.
A clinic can print on a compatible FDM printer or send the STL to a print service. Real print time depends on the printer, material, size, walls, infill, failed prints and finishing; use the slicer's estimate and validate each setup. More in how insole manufacturing is changing.
How much do custom orthotic insoles cost? What the price is made of
There is no universal fee. Prices vary by country, clinic and what is included. Before comparing, ask for an itemised quote: assessment, measurements or a cast, design, fabrication, delivery, follow-up and adjustments can be charged together or separately. Ergono3D pricing covers the design and STL export step only; it is not the price of finished clinical orthotics and does not include assessment, printing or follow-up.
| Item | What it covers | What to confirm |
|---|---|---|
| Assessment | Consultation, biomechanical or gait assessment | Whether it is charged separately |
| Measurements or cast | Cast, foam box, scan or measurements | Which method is used |
| Design and fabrication | Turning the data into the insole | Material and method |
| Delivery and fitting | Handing over and checking the fit | Whether a fitting visit is included |
| Follow-up and adjustments | Reviews and later changes | How many are included; replacement terms |
| Ergono3D | Parametric design and STL export | Current plan on the Pricing page; printing, material, finishing and follow-up are separate |
Where can you get custom orthotic insoles?
There are two common routes. In the clinical or lab route, a professional assesses the foot, prescribes the orthosis and arranges fabrication and adjustments. In a digital workflow, the clinic can turn its data and parameters into a printable STL and produce it in-house or with a local service. Time and cost depend on the equipment, material, validation and follow-up included. Ergono3D covers the design step; you can start with a free design preview.
Make them in your clinic with Ergono3D
Ergono3D is a browser-based tool for designing custom orthotic insoles without CAD or a scanner. From guided foot inputs you adjust the parameters — arch, heel cup, posting, skive, flange — review the geometry in 3D and export an STL ready to print in TPU, in your clinic or with a local print partner.
That lets you add a custom insole service without building a lab: the design is parametric and repeatable, and fabrication fits on a desktop printer.
Frequently asked questions about custom orthotic insoles.
How much do custom orthotic insoles cost?
There is no single fee: the price depends on the country, the clinic and what is included (assessment, fabrication, follow-up, adjustments). Compare itemised quotes with the same scope. Ergono3D's Pricing page covers only the design and STL export.
What does the price of custom orthotic insoles usually include?
It can include an assessment or biomechanical study, measurements or a cast, design, fabrication, delivery, follow-up visits and adjustments. Some clinics bundle these items and others charge them separately. Ask for an itemised quote and check whether follow-ups, later adjustments and a possible replacement are included.
Why do prices vary so much between clinics?
Because they don't always charge for the same things: some include the biomechanical assessment, follow-ups and adjustments, others charge them separately, and material, fabrication method and professional time also differ. Compare itemised quotes with the same scope.
Are custom insoles worth it compared with pre-made ones?
A pre-made insole offers a standard shape; a custom insole lets the geometry follow the data of one foot. The choice depends on symptoms, risk, activity, footwear, goals and professional assessment. Ergono3D designs files and does not decide on its own which clinical option a person needs.
What are the alternatives to custom insoles?
Pre-made insoles chosen by size and arch type; heat-moldable insoles adapted in the clinic; and insoles designed digitally and 3D printed. Which one suits depends on symptoms and a professional assessment.
Do I need a scanner to make custom orthotic insoles?
Not necessarily. With guided inputs, the insole geometry can be generated from measurements and structured answers, without a dedicated 3D scanner or CAD software. Digital capture (scanning, phone photogrammetry or pressure mapping) can add data but is not required to start.
Are custom insoles and personalised insoles the same thing?
In practice the terms are used interchangeably: both are made for one specific foot, unlike pre-made insoles chosen by size and arch type. What matters is how the foot data are taken (assessment, cast, scan or measurements) and who checks the fit.
Where can I get custom orthotic insoles made?
A podiatry or orthotics clinic can assess, prescribe and coordinate fabrication and adjustments. A clinic that already has professional judgement and production capacity can also use Ergono3D to design an STL and print it in-house or with a local service. Ergono3D covers the design file, not clinical care.
