- Take the orthotic and turn it upside down so that the shell is facing up.
Quick Answer To properly trim the topcover of custom orthotics, Seattle Foot and Ankle Center advises using the shoe's existing insole as a guide. Patients should turn both the orthotic and the shoe insole upside down, align the insole over the back edge of the orthotic shell, and then trace and cut along the toe end of the topcover. This process ensures the custom orthotics fit correctly inside the shoe, which is essential for both comfort and optimal function. After trimming, the original shoe insole should be removed to allow the custom orthotic to sit properly.

Custom orthotic - Take the insole out of your shoe, the one in which you plan to use the orthotic, one you wear a lot, or one that represents the size of shoes you wear. Make sure it’s the correct side as the orthotic, and turn it upside down as well.

Shoe insert - Take the insole and center it over the back edge of the shell.
- Take a pen and trace the toe end of the topcover.

Trace and cut orthotic topcover - Cut the topcover and place the orthotic in your shoe. Leave out the insole that came out of the shoe.
