Question

what is the sound of New shoe

Answer 1

They make a weird noise when u wear them. It sounds like it's coming from the mid sole area, when the foot arch doesn't touch the sole. Like some squeaky air pocket sound.
I guess.....

Answer 2

Sometimes air or moisture can get trapped between the insert and the rest of the shoe that can cause a squeak. The fit of the orthotic in the shoe can cause friction and therefore noise as well. One possible solution is to remove the insoles and sprinkle some baby powder into the shoes.
