No advice on alternate shoes, but when I was in EPCOT last week, there was a nasty thunderstorm and downpour. It was not one of those quick moving storms either, and I was caught in it in my best running sneakers. It was date night and we didn't have time to sit and wait for it to stop if we wanted to see World Showcase, so we sloshed through it and got my sneakers good and squishy. An hour or two later, when we got back to the room, I used paper towels to get out as much moisture as possible and then used the hair dryer in our room at the Poly. It took a couple minutes on each shoe, but after that and letting them dry overnight indoors, I used them the next day with no problem. DH stopped me from putting them on the balcony to dry further, pointing out that it was crazy humid outside and that likely any benefits the high temperature would have would be cancelled by the humidity.
