If I was a speck, where would I live on your sole ? Well if I was durable enough to not get easily crushed I would chose to live under the ball of your foot, get to snuggle with your wrinkles and be trampled all day.
And if I wasn't I would live in your first toe gap next to your big toe, it would be smelly, hot and I would have lots of toejam to feast on.
Of course in both cases I would worship your feet like crazy, loving and cherishing every single second even if I would get crushed relatively quickly.
