Custom Insoles: When You Need Them and How They Work
Custom insoles are one of the simplest and most effective ways to correct problems with how you walk and stand — and, in doing so, to relieve pain that often seems to have no explanation. Unlike off-the-shelf insoles, they are designed for your foot and the way you move.
But they are not for everything or everyone. Here we explain when they make sense, how they are made and what to expect.
What they are for (and which problems they solve)
The foot is the foundation of the whole body. When the way you place your foot is altered, that "fault" travels upwards: ankle, knee, hip and even the spine. The result: pain that appears far from its real source.
Custom insoles can help in situations such as:
Plantar fasciitis and heel pain.
Knee pain linked to how you walk or run (including runner's knee).
Metatarsalgia and pain in the sole of the foot.
Flat feet or high arches and misalignment.
Overload in sport, especially running.
Injury prevention for people who train regularly.
How we know whether you need them: the biomechanical assessment
The right insole starts with a good diagnosis. Before making anything, we carry out a biomechanical analysis of posture and movement — we look at how you place your foot, how you walk and how you run. Only then can we tell whether an insole is the answer, and exactly what correction it should make. Discover our movement analysis lab.
This step is what separates an insole that solves the problem from one that merely "feels comfortable".
How they are made: 3D technology
The process combines precision with complete personalisation:
3D laser scanning of the foot, for an accurate digital model.
Computer modelling of the correction, based on the biomechanical assessment.
3D printing of the insole, made exclusively for you.
The result is a light, precise insole adapted to your real needs — not to a generic mould.
What to expect
Getting used to a new insole is gradual, with an adaptation period of a few days. The aim is not to "get used to something foreign", but to correct the mechanics that were causing your pain. Insoles are often part of a broader plan, together with physiotherapy and movement retraining.
Frequently asked questions
Can anyone use custom insoles? Most people can, but it only makes sense after an assessment confirms there is something to correct. Not all foot or knee pain is solved with insoles.
How long do they last? It depends on use and activity. Because they are reviewed as you progress, we make sure they continue to meet your needs over time.
Do insoles replace physiotherapy? No. They correct the mechanical foundation; strengthening and movement correction complete the treatment. Together, the result lasts longer.
Can I run in them? Yes — sport is one of their most common uses, to spread load better and reduce the risk of injury.
