Actually, maybe unless wearing heavy army boots or so, I seriously suggest keeping your shoes on. You need something sturdy on your feed, in case you need body-forces to enforce "something", let alone, protect your feet against all sharp metal in and around the foot well. Most shoes "float" nowadays, so won't impact your floating (significantly). Not to say, when you land in water where you simply can stand, no need for shoes removal for the non-float-issue.
