What each one actually is
A quality store insole is generic support: a pre-shaped arch and cushioning built for the average of many feet. A custom orthotic is a prescription device: cast from a mold of your specific foot held in corrected position, then engineered for your diagnosis, posting angles to control rotation, offloading wells under painful spots, materials matched to your weight and activities. One cushions the path your foot already takes; the other changes the path.
When store-bought is honestly enough
Mild, recent arch or heel soreness in a fairly normal foot; a need for general comfort on hard floors; a first-line trial while a new problem declares itself. In those cases a well-chosen over-the-counter insert plus proper shoes is a legitimate strategy, and we recommend exactly that to a meaningful share of patients who ask about orthotics. The tell that it worked: symptoms clearly improving within a few weeks.
When custom earns its price
Custom devices justify themselves when mechanics are the disease: pain that returns every time generic support comes out, calluses that rebuild in the same spots, flat feet straining the posterior tibial tendon, neuromas needing precisely placed offloading, or diabetic feet where pressure distribution is medical, not comfort. The gait exam sorts which category you're in, and honesty matters both directions: a custom device for a foot that needed a $40 insole is waste, and a year of failed insoles for a foot that needed correction is a different kind of expensive.
Questions readers still ask
Why do custom orthotics cost so much more?
You're paying for the exam, the corrected-position casting, prescription engineering, lab fabrication, fitting, and adjustments, a medical device pathway rather than a retail product. Well-made devices also last 3 to 5+ years, which changes the per-year math considerably.
Do online 'custom' insoles from a foot scan count?
They're semi-custom at best: shaped to your foot's surface but not prescribed for a diagnosis or corrected posture, and nobody examines how you actually move. For comfort they can be fine; for fixing a mechanical problem, the prescription is the product, not the mold.
