This is my second pair - the first lasted five+ years.  Originally, I bought them for water shoes, but they are so comfortable that I wore them all summer long, stream, street or trail, for years.  On a hike, my new boots gave me blisters, so I wore these instead - no problems!  I wore them on a walking tour of the city and my feet were not tired at the end of the day.  I climbed a steep hill yesterday in them with no slippage - my heel stays firmly centered inside the footbed.  These beat my husband's Keen sandals hands down for weight and style.
