For Everglades City Florida just what I have been searching for.  I needed good water shoes for in the boat as well as wading, fishing and cast netting bait.  Good protection walking on oysters and in mud.  Excellent protection keeping out mud and sand out of the shoe.  Previous water shoes let in sand and mud or did not hold up to walking on oyster beds.  Even in Florida is not too hot but keeps feet warm when the water temp is below 75.  You will pay a little more but get what you pay for.

UPDATED May 2013:  Almost 4 months of heavy use (2 or 3 times a week) Still walking in mud and oysters while fishing and cast netting for bait.  There is no indication of wear or worn out material.  These shoes may take a few more seconds to take off-however, they fit well and conform to your feet.  I have disposed of all my other used water shoes as backups.  I have not slipped on the wet and/or muddy boat deck as I have with other shoes.

LAST UPDATE: March 2015:  This is the last update on this water shoe.  They are finally wearing out.  Mostly the upper part and some place in the lower part.  However, this shoes were bought in December 2012 almost 3 years ago.  They have been punished wading in mud, oysters and sand.  All of the Velcro stapes and the zipper still work and keep the shoe in place.  this is the longest lasting water shoe I have owned.
