I really believe worrying about whether there could be virus on your shoes is worry to far. Short of licking them, or putting your foot in your mouth how is the virus going to get into your system. If your worried about virus droplets falling on your shoes, perhaps you should also worry about where else a virus droplet could land on you. Such as your clothes or even your hair if someone coughs out of an upstairs window as you walk by.
It's all very well trying to avoid getting infected, but worrying about shoes says to me that some people have lost perspective.
Stay safe but be sensible. If you really are worried about your shoes. Wash your hands after handling them.
