The only ride they will get soaked on is Popeye. Yes, they announce everyone must have shoes on. Here's what I do. As I'm in the queue for Popeye, I take off my shoes, socks, ball them up in my pocket, and put my shoes back on. As I get into the raft, I put my seat belt on, then put my shoes in the middle holder. If the ride ops make me put them back on, then I hold my feet up during the ride, and my socks are dry in the middle compartment. If I get away with it, then I'm barefoot and enjoy.
Either way, I'm coming off the ride with dry socks, and that's what counts the most.
