When you take a shower do you wash the bottoms of your feet?

I always have and I was just taking a shower, and I remembered a discussion I had with an ex during a shower. He noticed I washed the bottom of my feet and looked at me weird. We got into a discussion.
My reasoning is that I’m taking a shower, I am cleaning myself, the bottoms of my feet are part of my body, why wouldn’t I? His reasoning for not washing them, was that soapy feet are slippery, and falling in the shower is dangerous, they will get cleaned by the suds that hit the shower floor.
During my shower I slipped while washing the bottoms of my feet, and thought I would ask my fellow Jellies.
