If you experience foot or knee pain you may have been referred to a Canadian Certified Pedorthist from your family doctor to see if custom made orthotics are beneficial for you. I am frequently asked what happens during the process of manufacturing the custom orthotics.
From start to finish, a pair of custom orthotics can take anywhere from 3-5 hours to make. After a complete biomechanical and gait analysis, a 3-dimensional mould of your feet are taken. At Align Pedorthics we use most commonly use a foambox cast. This is essentially the most important part of the process so sometimes 3-4 moulds will be taken in order to ensure the proper foot position.
The mould is filled with plaster, which when dry, will give us a replication of your feet to build the orthotics off of. Once the moulds are cleaned and smoothed out, the shell of the orthotic is made. The raw material (which can be plastic, EVA, cork, etc). is heated in the oven until completely flexible. It is vacuum pressed to the foot mould to give us an exact duplication of your arch. This shell is then cut down and shaped using a grinder. Materials of different densities and thicknesses are added to the shell in order give the appropriate amount of support for the person’s needs.
Making a pair of orthotics can take a lot of time and precision. Sometimes comfort is a matter of only a few millimeters or degrees so grinding takes a lot of skill. A major difference between pedorthists and other health care practitioners offering orthotics is the knowledge of the manufacturing process and how to make modifications when necessary.
If you are wondering if you could benefit from custom made orthotics, please do not hesitate to book a pedorthic assessment at 519-787-8111 or click here for online scheduling.
