I had a look the other day at some imitation Crocs. Much lighter than the real thing and no doubt not as durable but may do for light duty around camp.
What I do now is to take bread bags (plastic) with me and after I have a wash I put my coolmax liner socks on (night socks) , then the plastic bag and if cold enough the day socks on top of that.
(you need spare bags, they don't last for long)
so I go around with the laces undone. If you do that and trip over them, don't blame me...
