Custom, modified or off-the-shelf orthotics: what is the difference?
Orthotics are inserts worn inside shoes. A ready-made insert, a modified insert and a custom device are different options; the choice starts with your symptoms, footwear and assessment.
What are the options?
Off-the-shelf inserts have standard shapes; modified inserts adjust a prefabricated base; custom devices follow an individual prescription. These describe manufacture, not guaranteed benefit.
What should guide the decision?
Tell us what you hope to do more comfortably, which shoes you wear and how previous insoles felt. We’ll consider footwear changes or rehabilitation, with or without orthotics.
What should I ask before agreeing?
Questions about purpose, alternatives, shoe fit, follow-up and total cost are welcome. More expensive isn’t automatically better; devices are quoted separately.
What will the quote include?
Ask whether fitting, adjustments and reviews are included, and what costs extra. See the orthotics service page.
Unsure which option to consider?
Bring your usual shoes and existing insoles, especially uncomfortable ones.
