Full-length Superfeet insoles are supposed to be trimmed to fit in your shoes. If your insoles are too long:

• Trim them with household scissors.
• Leave a 1-2mm gap between the insole and the shoe's end.
• How To Trim Superfeet Insoles

Note: Superfeet's ¾-length insoles are not meant to be trimmed.

It’s a good idea to clean your Superfeet insoles occasionally.

• Handwash: Use mild soap and warm water.
• Brush: Use a soft-bristle toothbrush if needed.
• Rinse: Rinse well, remove excess water with a soft towel.
• Air Dry: Allow to air dry, but avoid heat sources.
• DO NOT MACHINE WASH OR DRY: The results aren’t pretty. Your insole will be damaged and its effectiveness will be compromised.

Most often this is caused by improper fit in your shoes. Here's how to check the fit:

• First, be sure the insole is trimmed correctly. Remove the Superfeet insole from your shoe.
• If you see creases in the foam at the toe or sides of the insole, you may need to do some additional trimming.
• Trim insoles slightly to ensure they move independently inside the shoe. Leave a 1-2mm gap between the insole and the shoe's end.
• Sprinkle baby powder or place a dryer sheet under the insole if the squeak persists.
• Test insoles in another pair of shoes to check if they are too wide.

For relentless squeaking, send photos of the insoles to customercare@superfeet.com and your receipt.

Superfeet insoles may require a break-in period of about two weeks.

For the first week:

• Wear the insoles for 1-2 hours on the first day.
• Increase to 2-3 hours on the second day.
• Gradually increase the duration each day.

Continue this process until your feet are accustomed to wearing the insoles all day long.
