I had a pair of Teva sandles before these. I wore them all summer, every summer for 8 years outdoors and indoors through rivers and mud and they never broke! I'm replacing mine now only because after 8 years of use and abuse the rubber in the soles is starting to stiffen making them slightly less comfortable. I've worn these now for one summer and love them. They are even more comfortable than my last pair, I wont wear anything else.
