3D Printed Custom Foot Orthotics

Our revolutionary orthotics were developed from cutting-edge foot care technology. Using the patented dynamic Footscan® and biomechanical measurements, we analyse your gait, identify issues and discuss solutions, which may include the prescription of orthotics.

Your bespoke state-of-the-art 3D-printed Phits® insoles are designed from data accurately gathered from over 4000 high speed sensors. They are made to individually fit each foot, and come with a two-year guarantee.

For the final stage of this service, you can choose whether to collect your orthotics from Fitstuff, or return to the clinic for a follow up appointment with Andy (for which there is an additional charge).

PHITS® Custom Insoles FAQs

What are PHITS® custom insoles?

PHITS® are fully customised, 3D-printed orthotic insoles designed following an assessment of how your feet move and respond to pressure. Each pair is tailored to your individual needs, whether you’re managing an injury, supporting rehabilitation or looking to improve comfort during walking or running.
Unlike insoles based mainly on the shape of your feet, PHITS® use dynamic Footscan® technology to assess pressure distribution while you walk or run across a pressure-sensitive mat. We combine these findings with a clinical assessment to create a personalised prescription.

Your appointment takes approximately 45 minutes. We’ll assess your walking using a pressure-sensitive mat, alongside an assessment of your foot and lower-limb function. Where appropriate, we’ll also assess your running to help develop your individual prescription.

No. PHITS® insoles can be used as part of injury management and rehabilitation, but they may also benefit people without an injury who are looking for additional support or comfort during everyday activities or running.

Custom orthotics may help manage conditions such as plantar fasciitis, Achilles tendinopathy and certain foot, ankle, shin, knee and hip problems where foot mechanics may be contributing to symptoms. We’ll assess whether insoles are appropriate for your condition.

Yes. Your insoles can be designed for running, everyday footwear or both. We’ll consider your footwear, activities and individual requirements when developing your prescription.

Your custom 3D-printed insoles typically take around 10–15 days to manufacture following your assessment.

The complete PHITS® assessment and a pair of fully customised, 3D-printed insoles costs £355. This includes your assessment, individual prescription, insoles and one modification if required.

It can take time to adjust to new orthotics. If your insoles need modifying, one adjustment is included in the initial price. Further assessment or support is available through a follow-up appointment costing £60.

PHITS® 3D-printed insoles are designed to be durable and can last five years or more, depending on use and wear. They come with a two-year manufacturing defect warranty. The top cover can also be replaced without needing to purchase a completely new pair of insoles.
