Best fix for squeaky boots?

I have a pair of barefoot african troopers I've had for a few months now. I put rose anvil leather insoles and kilties on them a bit after I got them and that made them fit way better. My only issue is that the insoles have made this squeaking sound in each boot every time I step from the leather rubbing on leather and it is driving me nuts. I thought they just had to get broken in and it would go away but it almost seems like it's getting louder every day. Anyone have any suggestions on how to get rid of the squeak so I'm not loud as hell walking around?
