RS Podiatry Clinic

Phits Custom-made Orthotics

We offer the latest in 3D printed Orthotics which are designed and based on your assessment and results of your dynamic Footscan.

The RS Footscan and V9 software

Cutting Edge Technology

The system is used in biomechanical research, sports clinics, labs and for elite sports men and women, including Paula Radcliffe. The Footscan is a highly sensitive and intuitive piece of kit which uses over 4000 sensors to gather intricate data during gait analysis. This data allows us to analyse the patients gait pattern in much greater detail.

The scan and V9 software combined, allow us to design your orthotics based directly on the data that it collects. In other words, your orthotics are tailor made to your walking or running pattern! Of course, our biomechanics knowledge plays a large part in tweaking the orthotics to suit the individual’s requirements and goals.

A ‘Phit’ for all!

Whether you’re a casual runner, elite athlete, recreational walker or have a job where you are on your feet all day, Phits orthotics reduce your risk of injury, help improve optimal performance during sports and improve your level of comfort.  

The orthotics can also be specially made to suit different styles of footwear e.g. safety boots, football boots, golf shoes and running shoes.

We are very proud to be the first Podiatry Clinic in Coventry and Warwickshire to offer this combination of service!

Below is a highlight of the Phits Workflow Process and the steps we take in analysing, designing and producing your Phits Orthotics.

Phits Expert Workflow

(included in your Biomechanical Assessment)

This will include a detailed history take and further musculoskeletal and/or biomechanical assessments as needed.

Each foot can be of a slightly different size. Therefore, each foot is separately measured against pre-set sizing templates. If one foot is for example half a size bigger the orthotic can be made half a size bigger whilst keeping the other foot size the same. Shoe size, suitability and fit are also checked.

First a static ‘pressure snap shot’ is taken with the patient stood still over the pressure plate. Then a live foot-balance and posture recording is taken again with the patient standing still. This shows us your weight distribution between each foot (left-right), between the front-rear of each foot and then the variance within all 4 quadrants (left/right front/back). It will also show how your centre of gravity (COG) is positioned.


Next, we observe the patient walking/running over the scan. This provides us with a number of detailed screens ready for the analysis phase. Screens include:

  • 2-D: showing peak pressures
  • Risk Analysis: indicating the risk of the patient developing a potential injury over a given area
  • 3-D: A 3-D visualization of the 2-D peak pressures
  • Load rate: Showing the rate at which force is applied to each anatomical zone on the foot.

Next you take a break, have a hot or cold drink whilst we analyse your scan results. Then we go through the findings with you in simple straight forward terms keeping medical jargon to a minimum. If it is decided that you would benefit from having orthotics and you would like to proceed then we move to step 5!

As your Podiatrist and Phits expert it is now our job to run through the prescription section of your orthotics. This is based on all of the clinical and scan data taken up to this point as well as keeping in mind the overall goal.

Once manufactured and quality checked, join us for the official unboxing of your brand-new 3D printed custom-made orthotics devices and have them fitted to your running trainers, golf shoes, football boots, or just your walking boots!

The production side

High-end Product

Phits 3D printed custom orthotics are produced using sate of the art technology by a Belgian company called Materialise. Materialise offer their services to some of the world’s biggest industries including medical, aerospace, automotive and art and design (

The orthotics are printed using a technique known as Selective Laser Sintering (SLS) which allows the printing to be up to 0.1mm in accuracy. This means a second pair of orthotics could be made identical to the first pair.

High Quality Materials

Our orthotics are made from high grade ultralight Polyamide 12 (PA 12). 200N/cm2 is already exceptionally high for a human footstep, however, tests on PA 12 show that the material does not wear out even if it is stressed to 2000N/cm2.


The result means your orthotic is thin, flexible, light-weight but durable. In fact, the base comes with a 2-year guarantee.
