How do custom-made orthotic insoles actually work?

An insole is a contoured orthotic device which alters the characteristics and biomechanics of the foot and ankle area. Biomechanics are concerned with mechanical laws and how they affect the living body, especially the musculoskeletal system.
Here, Alan Hews, senior orthotist at LOC, talks us through the process of making insoles and exactly how they can benefit an individual who experiences pain in the feet, legs or back.

But what actually are insoles and how do they work? They’re removable devices, often made from plastic or foam, that are designed to fit inside a shoe to provide additional support for your feet. As well as offering shock absorption, an insole can help distribute the weight of your body more effectively across the foot and can be made bespoke to cover a range of biomechanical conditions.
