ELI5: When I'm walking I'm heels, why do the "clop" noises my feet make always seem like they are 2 different pitches?

Is my brain just interpreting the pitches as different or for some reason are the pitches between the 2 feet actually different? I notice the same thing with anyone walking in heels.
