While a typical custom orthotic might last around 2-3 years on average, not every case is a typical one. Some people need theirs replaced every year, while others can get 5 years or more (occasionally much more) of use out of theirs.

There are three common types of orthotics known as soft, rigid, and semi-rigid. Soft orthotics are made to provide extra cushioning while the foot is planted on the ground. Semi-rigid orthotics, which are often used on flat feet, are designed to provide both cushioning and stability.

Custom-made orthotic devices may control pain if you have certain problems, such as an unusual-shaped foot, or if your foot rolls toward the arch (pronation). Custom-made orthotics are available by prescription. They can be costly, and provincial health plans or private health insurance may not pay for them.
