You live in a cursed place, where taking off your shoes will cause your feet to grow. You don't know it, but you must make every second of being shoeless count, or else your feet will become gigantic. Every time you take off your shoes and socks to shower, when you take off your shoes to go to bed, all this time without shoes will cause your feet to feel a comfortable, warm sensation, that makes you want to keep off your shoes and socks, and cause your feet to slowly plump up in size.
