The life span of custom fit orthotics depends on a number of factors, including the materials used, the level of care and maintenance provided, and how intense the user uses it. However, in general, you can expect to use custom orthotics 4-5 years, give or take.
Because these devices are custom to each foot, they tend to wear down more slowly than conventional shoes or inserts. If you get a pedorthist to fit and align the devices properly, it will help preserve the shape and function of your overall musculoskeletal system. Orthotics that are used regularly are likely to last longer than those that are only worn intermittently or seldom worn.
When choosing orthotics, it’s important to pay attention to comfort and fit as well as material quality and durability. An excellent pair of foot orthotics will fit comfortably and provide great support. A poorly fit device can lead to discomfort and pain within the foot or leg as well as a breakdown of the foot structure over time.
