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.

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.

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.

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.

• Recommendation: Wear socks to absorb moisture, reduce friction, and extend insole life.
• Sockless: If you prefer going sockless, clean and air out insoles regularly.
