I think in our modern pandemic world that people are giving a lot more thought to the things they touch and how they can be infected by others. Bare feet are probably right up on that list. You can't get COVID through your toes, but if you use your hands at all to touch your shoes, now you are transferring disease to your hands, which so often touches the face or mouth.
