Squeaky shoes

Hello. I have a pair of Scarpa Mojito trail GTX shoes that have developed a loud squeak with each steep. Its preventing me from been sneaky. I feel like a cat with a bell. I can only ambush atm.

Any tips on removing the sound?

Its coming from under the ball of my foot. I guess its the souls rubbing against something. Ive removed the in-soul to no avail. Bending the shoe back on itself fixes it for a few minutes. Maybe injecting a lubricant or adhesive into the soul?
