Store bought devices (such as insoles and arch supports) are not true foot orthotics, like the custom orthotics obtained from Chiropodists.
In Ontario, Chiropodists / Podiatrists are the only regulated health professionals whose legislated scope of practice includes the provision of orthotics. Thus Chiropodists / Podiatrists are able to prescribe, manufacture and dispense foot orthotics.
This is best done using one of two procedures, making a plaster cast for impressions or alternatively using a 3-D laser scanner.
The detailed report so generated is then sent to a specialized laboratory and customized orthotic devices specific to your biomechanical or foot condition are manufactured for you.
