I thought about that, but obviously don't know for sure.
There is an old school tradition (more from the baby-boomer and older generations) of shining your Sunday shoes before going to church. At the same time that this was a tradition, most people only had one pair of shoes that they considered their "Sunday" shoes. I can't imagine how bad that tradition is for leather, to gently wear a pair of shoes for a few hours at church, only to be put into the closet for another week before having more polish caked on top of the previous week's. And traditionally, they were not just buffing the shoes. Good old Kiwi was what was used.
