Putting things in my shoes is my go to. I don't wear shoes in the house so it's always the last thing I do before going out the door. If I put the thing on the door handle I'll just not see it. I can physically open my door without having to grab something handing from it. If they are physically in my shoes I have to actually grab the thing as the very last thing I do. So it reduces the chance I'll set it down and forget it.

I also only ever wear one pair of shoes unless I'm going to the gym or something. So no real worry of choosing the wrong shoes.
