How Do Custom Orthotics Work?

A clinician assesses your foot shape, joint movement, footwear, and walking pattern before selecting the insert's support and flexibility. The device may reduce pressure in one area while giving another area more contact or control. It does not change bone alignment permanently, and it cannot treat every source of foot or ankle pain. [Gait Retraining](/treatments/physiotherapy-and-rehabilitation/gait-retraining/) may complement an insert when walking mechanics need practice.

Start with the wearing schedule provided, especially if the inserts feel unfamiliar. Place them in suitable shoes, check your skin for rubbing, and report persistent discomfort or numbness. Bring your usual footwear to a fitting review. The insert material matters for cushioning and support; [EVA Foam Orthotic](/materials/eva-foam-orthotic/) is one material option. [Arch Pain](/symptoms/arch-pain/) and [Foot Pain](/symptoms/foot-pain/) may need other measures as well.

Arrange a review if pain steadily increases, a blister or pressure mark does not settle, or the device causes new limping, numbness, or weakness. Seek urgent assessment for a hot, rapidly swollen foot, a new wound, or sudden inability to bear weight, particularly if you have reduced sensation or circulation problems.

Ask what movement or pressure pattern the orthotic is intended to change, how to build up wear time, which shoes can accommodate it, and when its fit should be checked. Discuss whether physiotherapy or a different device is needed if symptoms persist.
