I wore these for 2 weeks trekking around in the humid hot jungles of the yucatan.  Pros:  they accommodated my wide feet, and I never overheated in them.  They had good support, i never had achy feet, and I felt comfortable even doing an in-water river float--the shoes did not feel heavy and cumbersome when wet.  Also, in places where you are going from town to jungle to city, it is nice to have a closed sandal because sometimes the strappy tevas feel too casual for city/restaurant/indoor use.  These were alittle more acceptable.  Also, when i got tired of wearing the back part up, i used them as mules and they stayed on which surprised me.  The cons:  two small blisters on heel, my fault for not breaking them in enough.  Eventually the back part stretched and it was fine.  Also developed a slight smell after constant beach use.  No I do not usually have stinky feet so....after I cleaned them they were fine again.  like other viewers said, they took a little time to dry if it wasn't sunny out, but in the sun it wasn't too bad.
