Either that or you’re right with a galosh.

I was thinking galoshes were those things that cover your pants (like a fisherman would wear a long with galoshes) when I read the title but realized that was incorrect, and now I can’t remember what those things are called 😩

Yes. For instance, if you wear one galosh and one flip-flop while walking through mud puddles, your footsteps will sound like “galosh! flip, flop.”
