This is a common question in pharmacies. And the answer is… yes, in the vast majority of cases.

The insole (or "original insole") is primarily used for comfort, hygiene, and sometimes aesthetics. However, it serves no biomechanical purpose. In contrast, an orthotic insole (or foot orthosis) is custom-made to correct a condition, relieve pain, or improve posture. The two insoles therefore do not serve the same function, nor are they positioned the same way in the shoe.

If you keep the original sole, you risk:

Not having enough room in the shoe (discomfort, tightness).

To interfere with the effectiveness of the orthotic insole.

Adjusting the height of the foot, which can lead to new imbalances.

By removing the insole, you can ensure that:

A better fit for the orthotic insole.

Better foot support.

Follow the pressure-relief zones recommended by the podiatrist.

As an exception to the rule, some very thin orthotic insoles (or those designed to be worn discreetly) can be worn on top of each other, but this is rare and should always be approved by a professional, such as your pharmacist.

A quick tip: When buying shoes to wear with your orthotic insoles, make sure the original insoles are removable, and try them on with your orthotics to ensure you’ll be more comfortable.
