Girls, do you find thin black layers of dirt in your shoes?

I know this question might sound a little gross but I'm thinking of getting into women's shoes business and I just want to know. Do you find these when your feet sweat? And do your feet always sweat or does it have to do with if the shoes are too tight or the heels are too high? Please explain, thank you! And don't be embarrassed if it sounds a little disgusting I'm used to it
