Propet Slip On Sneakers.

These are the best casual shoes I have ever owned in my life.

They do slip right on and off and if they get dirty, you rinse them under running water and then wipe dry. They are then ready to be worn again.

I can easily slip them off in flight and, if I need to get up and walk the aisle, they easily slip right back on. No need for your hands to assist either.
