Orthotics for flat feet
When designing orthotics for flat feet there are lots of different modifications you can do. Changes in the arch height, flexibility, rear foot and forefoot angles and more. In the video, we run through one example of a prescription we have done for a client.
The design
This design is for a client that has been coming for a fair few years now. We have tried a few different prescriptions over time to try and improve the outcomes but it seems the best for this client is to keep it fairly simple. The client has extremely flat feet and has suffered from chronic foot, knee and back pain and other injuries associated with having flat feet. They have a job that requires them to be on their feet all day and so the orthotics have been a massive help for him not only for work but for allowing them to play touch.
The prescription
This custom orthotics prescription has – A 3.5mm thick shell with a 2.5mm thick bar. The bar runs under the arch of the orthotic to help increase stability through this area without having to make the whole of the orthotic too thick. The arch height is exactly 20mm high. The rearfoot has a 6-degree angle tilting outwards, and a 6mm skive in the rearfoot (the flat spot at the heel which tilts the foot outwards even more).
The covers
To provide cushioning on the orthotics we have put a layer of poron under the arch. Poron is a highly durable, soft material that provides extra cushioning in this area. With the foot being so flat and so much force in the arch area, extra cushioning is required for the person to reduce the risk of blisters and callous build-up.
We then have a full-length E-tpu top cover. E-tpu is an extremely durable and bouncy material that’s commonly used as the soles of Adidas shoes. It doesn’t absorb moisture and is generally used for a more sports-based orthotic. This orthotic will be used in combination with a Brooks Beast shoe to provide maximum stability and get the most out of the orthotics.
Always remember that your orthotics are only as good as the shoes you put them into. Your podiatrist will recommend appropriate shoes to make sure you get the maximum benefits from your custom orthotics.
