I have a pair of the Chota's that I found on closeout at GI Joes for $7. At first I thought I would wear them all the time, however they very rarely get used. The problem I have had is with wading in any decent sized rocks, your toes get constantly smashed as your foot searches for firm footing. Makes for some very uncomfortable wading. A heavy neoprene sock under my normal Danner wading boots has been a much more comfortable option.
