Hi I didn't see lockers anywhere on the ki map in Soak City? Is there Lockers? Also if there's not, are you allowed to wear shoes on the slides or do they have designated areas for shoes?

There are lockers by the changing rooms in Soak City. Not sure of the shoe policy. Others will have to answer that one.

Shoes are not allowed on slides.   Maybe the lazy river.   There is not a designated area for them, people just kick them off by the fence.   Never had an issue with anyone taking our $5 Walmart flip flops.   This is fairly standard policy as I have never been to a waterpark that allows shoes on slides.  In fact on one of the slides no jewelry is allowed on including wedding rings and piercings.   

As you walk into SC there are lockers to the left by the shower house and also to the right by the changing stalls.
