Custom orthotics are molded inserts that cup the heel and support the arch during running. For 2026 training, they work best inside supportive running shoes with gradual break-in, steady mileage, and basic recovery care. They do not replace shoes, stretching, or smart progression. This guide shows what helps, what to expect, and how to stay safe.

Do orthotics help runners?
A randomized trial in runners found prefabricated orthotics in normal running shoes increased comfort and speed and lowered running-related injury rate. Higher comfort persisted after age and sex adjustment, according to World Journal of Orthopedics in its trial report. In that World Journal of Orthopedics analysis, researchers found no significant difference between prefabricated and customized orthotics for preventing running injuries.
They attributed benefit to distributing plantar pressure and cupping the heel and arch. For new runners, fit and comfort matter more than custom versus store-bought labels. Choose the pair that feels stable in your running shoes and lets you run with normal form.
What should you expect for heel pain?
Cochrane evidence on plantar fasciitis found custom-made orthoses may not reduce heel pain more than sham orthoses at 3 or 12 months. They also did not beat night splints alone. Combined orthoses plus splints may help, according to Cochrane Library in its review of plantar fasciitis treatments.
A British Journal of Sports Medicine systematic review reached a similar view. It concluded foot orthoses are not superior to sham or other orthoses for plantar heel pain and function. If heel pain persists, do not expect an insert alone to fix it. Seek clinical advice about shoes, stretching, and combined care options.
How do you break in new orthotics?
Clinical aftercare guidance says to break in custom orthotics gradually over about 2-3 weeks from short daily wear. Expect only mild foot, leg, or back soreness during this period, according to Revolutionary Foot and Ankle in its custom orthotics aftercare guide.
For running, wear them in supportive sneakers or running shoes with removable insoles and adequate depth and width. Lighthouse Foot and Ankle Center advises avoiding tight or narrow shoes that restrict movement or compress the device. Stop and contact your clinic if you notice:.
- significant pain
- blistering
- discomfort that does not improve
How do you train and recover with them?
UC Davis sports medicine advises runners to combine orthotics or foot support with proper shoes and stretching. It also warns against rapid increases in duration or intensity, in its running injury prevention tips. Raise duration or intensity slowly rather than jumping week to week.
Keep one training variable steady while you test the new inserts. Rapid jumps commonly cause shin splints, plantar fasciitis, and overuse injuries. Cut back and address shoe fit if pain appears during this phase.
When should you replace them?
Avid runners generally need replacement after 18 months to 2 years, versus 2 to 3 years for general use, according to Orthotics Plus Melbourne. Body weight and mileage compress materials and reduce shock absorption.
Regularly inspect for flattening, uneven wear, or returning pain. Replace sooner if support feels flat or old aches return on familiar routes.
