Hi Randy,
We appreciate you sharing this with us! We have found that when you have squeaky insoles, it is generally the interaction between the interior materials of some shoes and the insole that causes this sound when rubbing against each other. This can be remedied by using a bar of soap, wax, or stick deodorant to rub the underside and sides of the insole to help reduce friction. We are always working to solve this with every new generation of insoles we release but this has been extremely effective in the meantime.
We would love to hear how it works for you and let us know if you have any other questions.
Best Regards,
Drew
