There's a foam padding underneath? That might explain the problem I have with my Lakeshore boots. They squeak. It's effing annoying. I thought they'd stop but it's been months and I don't wear them often because it's so noticeable. I can feel the insoles making the squeaking noise through my feet. If the insoles have some kind of foam built in maybe I should just pull them out and get some leather insole replacements.
