I remember it was a pretty easy coaster(s) to ride, back in 2007. Even the standup was fairly smooth, to me. Since it was September when we were there, and an oncoming typhoon was going to challenge Elissa's train schedule skills another day (and she was SUCCESSFUL!), it wasn't very busy in the stations for this one, at that time.
^You know in Korea I've seen them give out little plastic bags to wrap over your feet about trainer high when you buy a poncho for their super splash at Gyeongju World so you don't walk around in wet feet... But for this, I think you'd need trash bag size and I'm still not sure your shoes would make it.
