try wearing flip flops made out of cloth, not plastic or rubber. crocs will get bad if there is any humidity, converses work as long as its not raining ( or if u dont have the brand name ones that have the holes in the side ) even tho everyone else had said dont do this i usually wear flats, they are made for ppl with smaller feet ( which is perfect for me). Anything flat to the ground is the best thing to wear for doing as lot of walking. Shoes that conform to your feet generally with make your feet cramp after alot of walking bc of not enough space inside the shoe.
