A foot orthotic is a device that is contoured to the entire foot and is used to reduce abnormal motion or posture of the foot. It can be used to treat a varied number of conditions from simple foot strains to more complicated postural imbalances.
The term foot orthotic gets used very loosely (in the industry). I would argue that a true foot orthotic is one that is made specifically for you. I would call all other available devices “arch supports.”
For many people, over-the-counter arch supports are adequate when needing something to provide a little more support to your feet. They can help with mild strains and fatigue. Not all arch supports are the same and not all arch supports will resolve your symptoms.
For a custom orthotic to work, multiple steps have to be taken. A proper diagnosis is key. This is achieved by performing a physical exam, gait assessment and biomechanical examination. Without knowing what needs to change or what needs to be corrected, a proper device cannot be prescribed. A proper 3D impression of the foot needs to be obtained. Favourable methods include: casting, foam box impression and 3D laser scans.
The clinician will then be able to prescribe the device determining multiple parameters including materials, style, cast corrections, additions, etc.
The last step is the manufacturing of the device. If this isn’t done to the correct specifications, the device will not feel comfortable or be of benefit. Devices should be made by a certified lab.
A lot needs to happen for an orthotic to work. Sometimes adjustments are required. Make sure you get your devices from someone who can make minor adjustments in house.
In my years of practice, I have seen many excellent orthotics prescribed and manufactured by competent practitioners, but unfortunately, I have also seen many poor devices.
Hopefully, this article helps you ask the right questions and make an informed choice.
Until next time.
